not known, you must do the following:

– Ensure that the heaviest devices are installed in the bottom of the rack

cabinet.

– If the rack cabinet you are relocating is part of a suite of rack cabinets,

detach the rack cabinet from the suite.

– Inspect the route that you plan to take when moving the rack to

eliminate potential hazards.

– Verify that the route that you choose can support the weight of the

loaded rack cabinet. Refer to the documentation that came with your

rack cabinet for the weight of a loaded rack cabinet.

– Verify that all door openings are at least 760 x 2030 mm (30 x 80 in.).

– Ensure that all devices, shelves, drawers, doors, and cables are secure.

– Ensure that the four leveling pads are raised to their highest position.

– Ensure that there is no stabilizer bracket installed on the rack cabinet

during movement.

– Do not use a ramp inclined at more than ten degrees.

– Once the rack cabinet is in the new location, do the following:

- Lower the four leveling pads.

- Install stabilizer brackets on the rack cabinet.

- If you removed any devices from the rack cabinet, repopulate the rack

cabinet from the lowest position to the highest position.

– If a long distance relocation is required, restore the rack cabinet to the

configuration of the rack cabinet as you received it. Pack the rack

cabinet in the original packaging material, or equivalent. Also, lower the

leveling pads to raise the casters off of the pallet and bolt the rack

cabinet to the pallet.

xxviii IBM Virtualization Engine for Tape TS7520: Introduction and Planning Guide

Chapter 1. Introduction

The TS7520 Virtualization Engine is a high-performance, high-capacity open

systems virtual tape product designed to augment the tape backup and restore

process in large tape environments. The TS7520 emulates an IBM 3584 tape library

populated with Linear Tape-Open (LTO) 2, LTO 3, and 3592 tape drives to increase

the speed and reliability of existing third-party backup applications. The TS7520

leverages your existing Fibre Channel SAN to transfer data to and restore data from

disk-based virtual tape at ultra-high speeds.

As in a conventional tape system, TS7520 virtual tape libraries support bar codes

as a mechanism to identify tapes. However, because they are virtual, the TS7520

eliminates the common problem of backup applications being assigned large tapes

and then actually using only a fraction of the total space. With the TS7520, you can

create virtual tape libraries and the system automatically allocates additional space

as needed.

Because you might already have physical tapes that you would like to protect, data

from physical tapes can be imported into your virtual tape system. If you ever need

to recover files from a physical tape, you can use the TS7520 to access those

tapes for immediate recovery. For additional data protection, or to free space in the

TS7520, the data on virtual tapes can be exported to physical tapes. Data can also

be copied to physical tapes using your backup application’s copy function.

The TS7520 is designed to aid in the tape backup and restore process by providing

customers significant operational and throughput efficiencies via tape virtualization,

namely:

v Backup window reduction

v Restore time reduction

v Data sharing and resource virtualization facilitation

v Operational efficiencies and management improvement

v Total cost of ownership reduction

v Capability to allow multiple disparate backup applications to share the same

physical resources

v High availability options

v Improved sharing of tape libraries across applications and servers

v Integrated server, disk, and tape solution for IT Optimization

The TS7520 is a tape virtualization solution for open systems attachment over Fibre

Channel interfaces. With TS7500 version 2 release 1, iSCSI attachment is also

supported. Significant operational efficiencies can be achieved by storing the daily

backup in the TS7520 disk cache. As backup data ages, the older data may be

migrated to physical tape for longer term storage. Since daily backup data is now

written to virtual tape via the disk cache, heavy daily tape drive usage is greatly

reduced. Fewer personnel are typically needed to administer the backup process

when it includes virtual tape.

A TS7520 equipped with one TS7520 Virtualization Engine Server has up to eight

Fibre Channel ports available for host or tape attachment. A TS7520 equipped with

two TS7520 Virtualization Engine Servers has up to sixteen Fibre Channel ports

© Copyright IBM Corp. 2005, 2007 1

available for host or tape attachment. With up to 16 fibre Channel interfaces, a two

node TS7520 can connect up to 8 ports directly to tape SAN. With four nodes, this

number increases to 16.

The TS7520 differs from many other open systems virtual tape products, by

enabling either parallel tape attachment or direct tape attachment. In parallel tape

attachment, physical tape drives or libraries are attached to the host server and

data is transferred from the TS7520 through the host server to physical tape drives

or libraries that are physically attached to the host server. In direct tape attachment,

physical tape drives or libraries are physically attached to the TS7520.

Backup window reduction may be achieved in many installations. Since robotic

movement, tape load/thread, and physical tape search and rewind is eliminated in

virtual tape, the effective utilization of the Fibre Channel interfaces is increased.

That means more tape jobs can be run to virtual tape over a single interface than to

physical tape. If the backup window is reduced, the time allowed for migration to

physical tape is increased, thus potentially reducing the number of physical tape

drives and media needed for longer term backup data storage.

Business continuity is increased providing better restore time objectives. Restore

times are decreased if the data is in the disk cache of the TS7520. With the

TS7500 V2R1, 1024 virtual tape drives, and 128 virtual tape libraries, each backup

server can be allocated their own virtual resources, allowing multiple and disparate

backup applications to use the same physical resources. This provides the potential

for infrastructure simplification. Multiple different tape libraries and tape drives can

be aggregated to one or more TS7520s, centralizing the backup resources and

further reducing the operational cost.

TS7520 Cache Controller (3955-SV6)

The TS7520 Cache Controller comes with two RAID controllers, providing dual,

redundant controllers. In addition, each RAID controller supports direct attachment

of two 3954-CV6s that contain two fibre channel host bus adapters each. External

cables and small form-factor pluggable (SFP) modules connect the TS7520 Cache

Controller to the storage expansion enclosure and the host servers.

Currently, the only storage expansion enclosure model that can be attached to the

TS7520 Cache Controller is the 3955 SX6.

TS7520 Cache Module (3955-SX6)

The TS7520 Cache Module supports up to 16 500 GB SATA Disk Drive Modules

(DDMs), offering up to 8.0 TB when using 500 GB SATA DDMs. The TS7520 Cache

Module utilizes the latest SATA disk drive technology and is designed with

redundant 4 Gbps Fibre Channel connections, offering reliability and performance.

The TS7520 Cache Module supports redundant, dual-loop configurations with the

3955 SV6 and other TS7520 Cache Modules. External cables and small form-factor

pluggable (SFP) modules connect the controller to the TS7520 Cache Module.

Using the default library configuration

The TS7520 Virtualization Engine comes preconfigured with two virtual 3584

libraries per Virtualization Engine. Each library is comprised of 12 virtual LTO 2 tape

drives and 253 slots. Each library is preconfigured with virtual tape cartridges. The

number of tape cartridges preconfigured is proportional to the total system capacity.

Up to four cards are available for host connection: any combination of fibre channel

(dual ports) or Ethernet (quad ports). A minimum of one card is required for host

connection. Up to two fibre cards (4 ports) can be dedicated to physical tape

connection. Up to two ethernet cards (8 ports) may be used for network replication

connections.

The default libraries are accessible when the TS7520 is powered up. You can

immediately start using these libraries without any additional configuration

necessary through the VE Console. However the VE Console provides information

that is helpful in creating the necessary zones when connecting to a storage area

network (SAN).

If you are not connecting the TS7520 to a SAN, you can directly cable your backup

server or host to one of the target ports and perform a device discovery (the same

as you would a physical library). From the rear of the TS7520 the default target

ports are PCI Slot 3 Port 1 or PCI Slot 4 Port 1 if 2 fibre channel cards are added

to the default 2 which are required.. Each port is assigned to one of the default

libraries.

If you are connecting to a SAN, you will need to zone the target world wide port

name (WWPN) of the TS7520 with the WWPN of your backup server or host.



For additional information about the default library configuration, see “Default library

configuration” on page 57. You can also refer to the IBM Virtualization Engine for

Tape TS7520 User’s Guide.

Data management and advanced features

The TS7520 Virtualization Engine is designed with the following data management

and advanced features that allow you to securely process and access your data

according to your business needs even if it is 24 hours a day and 7 days a week.

RAID

Redundant array of independent disks (RAID) is a method of configuring multiple

disk drives in a storage subsystem for high availability and high performance. The

collection of two or more disk drives presents the image of a single disk drive to the

system. In the event of a single device failure, data can be read or regenerated

from the other disk drives in the array.

The TS7520 supports groups of disk drive modules (DDMs) in RAID 5. RAID 5 is a

method of spreading volume data plus data parity across multiple disk drives. RAID

5 increases performance by supporting concurrent accesses to the multiple DDMs

within each logical volume. Multiple spare drives are allocated in the TS7520 cache

to increase the redundancy.

In the case of a DDM failure, the TS7520 Cache Controller will automatically

configure a spare to take over the role of the failed drive. Data and parity will be

rebuilt on the “spared in” drive. Upon replacement of the failed drive with a new

one, the TS7520 Cache Controller will “spare out” the previous spare drive to a

backup (or spare) role again.

Failover/failback

TS7520 Virtualization Engine’s failover/failback option provides high availability for

TS7520 Virtualization Engine operations by eliminating the down time that can

occur should a TS7520 Virtualization Engine Server (software or hardware) fail.

In the TS7520 Virtualization Engine failover design, a TS7520 Virtualization Engine

Server is configured to monitor another TS7520 Virtualization Engine Server. In the

event that the server being monitored fails to fulfill its responsibilities to the SAN

Clients it is serving, the monitoring server will take over its resources.

TS7520 Virtualization Engine uses a unique monitoring system to ensure the health

of the TS7520 Virtualization Engine Servers. This system includes a self-monitor

and an intelligent heartbeat monitor.

The self-monitor is part of all TS7520 Virtualization Engine Servers, not just the

servers configured for failover and provides continuous health status of the server. It

is part of the process that provides operational status to any interested and

authorized parties, including the Console and supported network management

applications through SNMP. The self-monitor checks the TS7520 Virtualization

Engine processes and connectivity to the server’s storage devices.

In a failover configuration, TS7520 Virtualization Engine’s intelligent heartbeat

monitor continuously monitors the other server through the same network path that

the server uses to serve its own clients.


Failover requirements

Follow these requirements when setting up a failover configuration:

v You must have two 3954 CV6 in a single 3952 F05 frame

– Failover to another CV6 in a different F05 frame is not possible, because both

SV6 must have access to the same disks.

v Static IP addresses must be used

There are two IP addresses needed for each adapter. One IP address is for

management, which you use for your VE Console, called Server IP address. And

one IP address is used for heartbeat connection, called Service IP address

– Two IP addresses for first heartbeat (service) connection and management

(sever) connection on each node for eth1

– Two IP address for second heartbeat connection and management connection

on each node for eth1- must be on different subnet than the first heartbeat

connection

v A physical tape library, if used, must be connected to both CV6

v No replication between the both TS7520 is allowed.

For additional information about the Failover option, see the IBM Virtualization

Engine for Tape TS7520 User Guide.

Network replication

Replication protects the data on a virtual tape by maintaining a remote copy of the

virtual tape on another TS7520 Virtualization Engine Server (called the target

server) over the IP network.

At prescribed intervals, when the tape is not in use, changed data from the primary

virtual tape is transmitted to the replica resource on the target server so that they

are synchronized. The target server is usually located at a remote location. Under

normal operation, backup clients do not have access to the replica resource on the

target server.

If a disaster occurs and the replica is needed, the administrator can promote the

replica to become the primary virtual tape so that clients can access it.

For additional information about the Replication option, see the IBM Virtualization


Physical Copy on Export

Physical Copy on Export exports data to physical tapes whenever a virtual tape is

exported from a virtual library (such as from a backup application or other utility). In

order to use this feature, the physical tape library must support barcodes. When the

TS7520 attempts to export to a physical tape it must find a matching barcode in a

physical library (you do not need to specify which physical library). If you use Auto

Archive, determine if you want the virtual tape copied (retained) or moved

(removed) after the data is transferred. If you select to move the virtual tape,

indicate how long to wait before deleting it. Also, indicate if you want to export your

physical tapes after archiving.

For additional information about Auto Archive, see the IBM Virtualization Engine for

Tape TS7520 User Guide.


Network Copy on Export

Network Copy on Export replicates data to another TS7520 server whenever a

virtual tape is exported from a virtual library (such as from a backup application or

other utility). If you use Auto Replication, determine whether you want the virtual

tape copied (retained) or moved (removed) after the data is replicated.

For additional information about Auto Replication, see the IBM Virtualization Engine

for Tape TS7520 User Guide.

Enhanced tape caching

The Enhanced Caching option enhances the functionality of TS7520 by acting as a

cache to a physical tape library, providing transparent access to data regardless of

its location. With the Enhanced caching option, tapes will always appear to be

inside virtual libraries and will be visible to the backup application regardless of

whether the data is actually on disk or tape. This means that the backup application

will always have direct access to data regardless of whether the data is on disk or

on physical tape.

4-way node support

This permits the sharing of all virtual media among all four potential CV6 servers.

Any virtual library’s medium changer and media will be available to any CV6

(subject to the user-specified definitions). CV6s will maintain their own virtual drives

and failover will only be done to a preassigned CV6 housed in the same rack. In

addition, implementation of the virtual pass-through function which permits volumes

to be moved between CV6s via a shared virtual shelf or vault will be performed.

NDMP

The NDMP backup support option allows backup applications and NAS devices to

perform backup and restore using the NDMP version 4 protocol over an IP network.

With this enabled the TS7520 acts as an NDMP server, centralizing management

while eliminating locally attached tape devices from each NAS device. When a

backup occurs, data is moved from a NAS device directly to the virtual library.

Note: This option is not needed when presenting a virtual tape library over FC to a

NAS filer as a replacement for a physical library.

Remote copy

You can copy the contents of a single tape to a remote target server. Because the

Remote Copy feature replicates the full tape rather than appending to an existing

virtual tape, you can only copy a tape if there is no virtual tape on the remote target

server with the same barcode. Therefore, if you have copied this tape before, you

must delete the copy from the remote target server before continuing.

For additional information about the Remote Copy feature, see the IBM

Virtualization Engine for Tape TS7520 User Guide.

CPF/DPF

Through a chargeable feature, Control Path Failover and Data Path Failover are

available to provide redundant access to virtual drives contained within virtual

libraries. This works the same as it does in the IBM 3584 library in that it allows the

host to create virtual copies of drives based on different physical paths to the

device. If a physical path between the host and the TS7520 goes down, the

command is retried at the device driver level on an alternate path.


Import/export

Because you might already have physical tapes that you would like to protect, data

from physical tapes can be imported into your virtual tape system. If you ever need

to recover files from a physical tape, you can use the TS7520 Virtualization Engine

to access those tapes for immediate recovery.

The import function allows you to:

v Copy the contents of a physical tape to a virtual tape

v Directly access a physical tape without copying the entire tape

v Recycle a physical tape

For additional data protection, the data on virtual tapes can be exported to physical

tapes for long-term data archiving. Data can also be copied to physical tapes using

your backup application’s copy function.

When you export, TS7520 Virtualization Engine copies/moves the contents of the

virtual tape to a physical tape. Because some third-party backup applications alter

what they write to the tape depending on the type of cartridge used, TS7520

Virtualization Engine only exports tapes to like media. You cannot export to a

dissimilar physical tape. Exporting tape to like media will enable the backup

application to accept the tape as valid; from the backup application’s point of view,

there is no difference between the virtual and physical tape.

Note: If you will be importing data from physical tapes into your virtual tape library

or exporting virtual tapes to physical tapes, you must assign your physical

tape libraries/drives to the TS7520 Virtualization Engine.

For additional information about importing and exporting, see the IBM Virtualization


TS7520 limitations

The following list describes known limitations for the TS7520 Virtualization Engine.

v The TS7520 provides emulations of LTO2, LTO3, and 3592 J1A and E05 drives,

TS3310 (3576 Models L5B and E9U), TS3200 (3573 Model L4U) and TS3100

(3573 Model L2U)- with LTO3 drives; 3583 (Models L18, L36, and L72) - with

LTO3 drives; 3584 with 3592 (J1A or E05 drives), that are sufficient for

successful operation and behavior with the listed supported ISV applications

running on server platforms with fabric components specified in the following IBM

support Web site:


The Virtual libraries/drives will include: 3584 (Model L22 for 3592 J1A and E05

drives and L32 for LTO2 and LTO3 drives ); TS3310 (3576 Models L5B and

E9U), TS3200 (3573 Model L4U) and TS3100 (3573 Model L2U) for LTO 3

drives; 3583 (Models L18, L36, and L72) - with LTO3 drives; and Inquiry strings

for “TS7510” and “TS7520”.

IBM claims that the TS7520 provides a sufficient emulation of the specified tape

drive and library interface architecture to support successful operation of listed

supported applications. IBM does not claim that every command of the full native

drive or library architecture is supported. Only those portions necessary to enable

successful operation of the cited ISV applications are supported by IBM.

v While the TS7520 supports failover in the case of a TS7520 Virtualization Engine

Server (3954 CV6) failure and supports multipath redundancy in its internal



access to the TS7520 Cache Controllers (3955 SV6s) and TS7520 Cache

Modules (3955 SX6s), the failover is not transparent. Depending on the ISV

being used, backup jobs may have to be restarted.

v Any fabric component (switch port or direct host or tape attachment) that is

directly connected to the TS7520 must be loop-protocol-capable.

– Switch ports that attach to the TS7520 must support fabric loop (FL) ports.

(Other switches in the fabric that do not connect to the TS7520 are not

required to support FL ports.)

– Tape drives that attach to the TS7520 directly (and not through a fabric) must

support node loop (NL) port attachment.

v The TS7520 does not currently support FCTAPE link recovery. Some link events

will not be recoverable transparently. Customer tasks may be interrupted,

requiring a restart.

v An import task that encounters a not-ready condition from a physical tape drive

may require user intervention to recognize the stalled task and initiate

cancelation.



Chapter 2. Physical planning specifications for the TS7520

This section provides physical planning and site specifications for the TS7520

Virtualization Engine. Before the TS7520 Virtualization Engine is installed at your

site, verify that your planned installation site meets these requirements, or prepare

the site so that it does meet these requirements. Preparations might involve

meeting area requirements, environmental requirements, and electrical

requirements for TS7520 Virtualization Engine installation, service, and operation.

Site preparation

Use the following information to prepare a location for installation of the system’s

components.

Prepare a floor plan that includes the following information:

v Power outlet locations, types, and ratings

v Frame locations

v Operator and service clearances

v Dimensions of the area containing all system components

Before hardware installation can begin, the local installation planning representative

must verify that all installation planning and preparation is complete. Additional user

responsibilities include planning for the following:

v Cabling and wiring for connections to the host

v Cooling and heating

v Telephone service

v Safety and security

v Fire detection and suppression

v Floors (both raised and non-raised) that meet the operational and structural

requirements necessary for the system components

Calculating space requirements

When you plan the installation location, you must first calculate the total amount of

space that is needed for the TS7520 units, including all service clearances and

weight distribution areas.

Lighting considerations

The 3952 Tape Frame and TS7520 Virtualization Engine are designed for lights-out

operation. No special lighting considerations apply.

Upgrade considerations

When planning for system installation, consider any potential future growth such as

the addition of expansion frames. Consult your IBM representative for current

planning information regarding upgrades to the 3952 Tape Frame and TS7520


Accommodating cables

Review the following considerations when planning for cabling accommodations:


v Electrical power cabling should be planned in advance of delivery of the TS7520.

This planning includes cabling for a second source if the dual power option has

been ordered and if independent sources are intended to be used.

v Fibre channel cabling from the TS7520 adapters to the attaching customer

servers or customer switch fabric should be included in the planning, as well as

fibre channel cabling from the TS7520 to any attached physical tape drives and

libraries. In addition, customers should plan for the fibre channel cabling from the

TS7520 base frame to the TS7520 expansion frame (if present).

v Ethernet cabling will be required for attachment of the TS7520 to the operator

console or consoles and to the network for replication and for call-home

reporting. For optimal service, IBM requires that at least one VE Console system

must be installed within 50 feet (15.25 meters) and within line of sight of the

TS7520 3592 Tape Frame.

v Failover configurations require a network connection for the corresponding

Ethernet ports on the two TS7520 Virtualization Engine Servers for mutual

operational state monitoring.

Height requirements

The minimum floor-to-ceiling clearance required for installation of the 3952 F05

Frame is 1.83 m (72 in.), including all installation, operating, and service

clearances. The 3952 F05 Frame is moved on casters and has four leveling pads.

The frame’s nominal height is 1.815 m (71.5 in.) from the bottom of the leveling

pads to the top of the frame. The leveling pads can vary the height of the frame by

up to 30 mm (1.2 in.). The pads are completely raised when the frame is shipped to

allow it to roll on its casters. The shipping height of the frame on its casters is 1.8 m

(70.9 in.).

Dimensions and weights of models

When you are planning the floor and space requirements for your storage units,

consider the dimensions and weights of your configuration components.

Operator and service clearances

Clearances are required around system components for the operator and the

service representative to perform certain tasks. See Table 4 for specific clearance

requirements for each frame type.

Table 4. Operator and Service Clearance Requirements

Component Area Size (Width × Depth) (see note 1)

3952 Tape Frame (see note 2) 644 mm × 1102 mm (25.4 in. × 43.4 in.)

Notes:

1. Size is defined by the depth from the outside of the frame and either the width

of a standalone frame or the length along any frames installed side-by-side. The

width is on a frame-to-frame basis; space required in front or behind each frame

is additive. The access space for individual frames overlaps.

2. Required clearance around the 3952 Tape Frame is listed below:

v Front: 690 mm (27.2 in.)

v Back: 660 mm (26.0 in.)

v Side: 0 mm (0 in.)

Unlike weight distribution areas that are required to handle floor loading, keep in

mind that service clearances of adjacent unrelated storage units can overlap.

Note: The terms service clearance and weight distribution area are often confused

with each other. The service clearance is the area that is required to open

the service covers and to pull out components for servicing. The weight

distribution area is the area that is required to distribute the weight of the

storage unit.

Aisle and door clearances

Two persons should be available to move system components between locations.

The following are the minimum aisle and door dimensions for moving components

from one location to another.

Floor requirements

A 3952 Tape Frame can be installed on a raised or solid floor meeting the minimum

leveling and floor-loading capacity requirements.

Floor level requirements

The leveling pads on the 3952 Tape Frame can be adjusted to compensate for an

uneven floor where the frame is to be installed. The maximum out-of-level condition

is 25.4 mm (1 in.) over the frame’s length and width.

Note: IBM strongly recommends that stringers be installed between all corner

posts. In addition, a post should be placed under the areas where the

frame’s leveling pads sit. As an alternative to placing posts under the leveling

pads, a post may be placed at the midpoint of the stringers in the areas

where the frame sits.

Weight distribution and floor loading

If the 3952 Tape Frame is installed on a raised floor, the raised floor should be

stabilized to prevent a horizontal shift of the raised floor structure. IBM recommends

a floor load rating of at least 341 kg/m2 (70 lb./ft.2). These ratings do not include

additional loading by personnel and equipment traffic.

Security considerations

Controlling access to the 3952 Tape Frame and TS7520 Virtualization Engine is the

user’s responsibility. The system should be installed in a controlled-access area to

prevent unauthorized access to the system’s internal components and to the

TS7520 Virtualization Engine VE Console.

Operating environment requirements

You must meet specific operating environment requirements at all the air intake

locations of your models.

The operating points vary depending on the state of the model. The models can be

in the following states:

v Operating

v Powered off

v In storage

v In transit

Table 5 on page 23 lists the acceptable temperature and humidity ranges in which

the TS7520 Virtualization Engine is designed to operate.

Notes:

1. The nonoperating environment must not exceed the operating environment

limits for longer than 60 days.

2. The storage environment must not exceed the operating environment limits for

longer than 1 year.

3. Substantial deviations from the suggested operating range, in either direction, if

sustained for extended periods of time, will expose the unit to greater risk of

failure from external causes.

levels indicate an upper limit, below which a large portion of machines operate.

Sound pressure levels in your location might exceed the average 1-meter values

stated because of room reflections and other nearby noise.

Considering safety issues

You must consider various safety issues when you plan your TS7520 series

location.

The following list identifies some of the safety issues you must consider:

v Fire suppression

v Earthquake safety

Providing a fire-suppression system

You are responsible for providing a fire suppression system for your TS7520.

IBM designs and manufactures equipment to internal and external standards that

require certain environments for reliable operation. Because IBM does not test any

equipment for compatibility with fire-suppression systems, IBM does not make

compatibility claims of any kind. IBM does not provide recommendations on

fire-suppression systems.

Consult your insurance underwriter, local fire marshal, or local building inspector

about selecting a fire-suppression system that provides the proper level of coverage

and protection.

Earthquake effects

There is no guarantee against equipment damage as a result of an earthquake.

Many factors influence the stress imposed on system equipment, including:

v Intensity and duration of the earthquake

v Equipment structural strength and durability

v Equipment location within a structure


v Equipment installation method

v Building type

v Soil conditions

Guarantees of equipment reliability cannot be made for all earthquakes and

conditions. The damaging effects of an earthquake are minimized by appropriate

installation and planning techniques. Significant sliding and rocking of equipment

during an earthquake might directly or indirectly result in damage. The following

steps can help minimize damage:

v Position equipment far enough from walls to prevent or minimize collision.

v Ensure that power and accessory cables are long enough to accommodate

sliding and flexing during an earthquake.

v Ensure that cable clamps or other strain reliefs are secured properly to

equipment.

v Secure several tall units together to form a more stable structure.

v Use a flexible restraint that allows a limited amount of movement, approximately

75 mm to 150 mm (3 in. to 6 in.), to dissipate energy imparted by the

earthquake.

The 3952 Tape Frame provides the frame that contains the various components of

the TS7520. One or two TS7520 Virtualization Engine Servers can be installed in

the base unit 3952 Tape Frame with the following features:

v 9326 (Plant Install a 3954 Model CV6) - To have the factory install one TS7520

Virtualization Engine Model CV6 into a new 3952 Tape Frame shipping from the

plant. A minimum of one must be installed in the 3952 Tape Frame designated as

the base unit (#7317), one as a limited edition unit (#7319), and a minimum of

two as the secondary base unit (#7320). A corresponding feature number 5728

(Plant Install a 3954 Model CV6) must be ordered on the 3952 Tape Frame, one

for each TS7520 Virtual Engine Server.

v 9327 (Field Merge a 3954 Model CV6) - to ship a second TS7520 Virtualization

Engine Server for field installation into an installed 3952 Tape Frame designated

as the base unit (#7317). A corresponding feature number 5729 (Field Install a

3954 Model CV6) must be ordered on the 3952 Tape Frame. At least one

TS7520 Cache Module must be installed at the same time.

The TS7500 V2R1 software (5697-N65 or 5697-N66) must be ordered and installed

with each TS7520 Virtualization Engine. This software is preloaded on the TS7520

Virtualization Engine Server by specifying the following feature:

v 9302 (Enterprise Edition VE Preload - AAS) -to have the factory install the

5697-N65 program.

v 9303 (Limited Edition VE Preload - AAS) - to have the factory install the

5697-N66 program.

The following other features are available on the TS7520 Virtualization Engine

Server:

v 1682 (Path Failover) - enables automatic control path failover to a

pre-configured redundant path without aborting the current job in progress. It also

provides failover for multiple redundant paths in a SAN environment by

automatically providing error recovery to retry the current operation using an

alternate, pre-configured paths without aborting the current job in progress. This

can provide flexibility in SAN configuration, availability, and management.

v 7420 (Failover/Failback) - enables hardware connections between two installed

TS7520 Virtualization Engines in the same 3952 Tape Frame. Failover/Failback

provides the ability for the host connections and jobs being performed on a

server in a failover pair to be moved to the surviving server of the failover pair in

the event of a server failure.

v 7421 (Network Replication) - enables the TS7520 Virtualization Engine Server

to support the Network Replication function in the TS7500 V2R1 software. If this

feature is installed on one TS7520 Virtualization Engine Server in a 3952 Tape

Frame, and a second TS7520 Virtualization Engine Server is installed in that

frame, and Failover/Failback will be configured, then both TS7520 Virtualization

Engine Servers should have this feature installed. Both the local and target

TS7520 Virtualization Engine Servers must have feature numbers 7421 and 7422

enabled for Network Replication to operate.

v 7422 (Network Encryption) - enables the TS7520 Virtualization Engine to

support the Network Encryption function in the TS7500 V2R1 software. If this

feature is installed on one TS7520 Virtualization Engine in a 3952 Tape Frame,

and a second TS7520 Virtualization Engine is installed in that frame, and

Failover/Failback will be configured, then both TS7520 Virtualization Engines

should have this feature installed. Both the local and target TS7520 Virtualization

Engines must have feature numbers 7421 and 7422 enabled for Network

Encryption to operate.


v 7423 (Network Compression) - enables the TS7520 Virtualization Engine to

support the Network Compression function in the TS7500 V2R1 software. If this




should have this feature installed. Both the local and target TS7520 Virtualization

Engines must have feature numbers 7421 and 7423 enabled for Network

Compression to operate.

v 7424 (3494 Support) - enables attachment of a 3494 library to the TS7520

Limited Edition. Although the actual library is not emulated, the drives can be and

therefore logical volumes can be exported to physical volumes in the 3494

library.

v 7425 (Hosted Backup) - Enables backup operations to be installed on the

TS7520 eliminating the need for a dedicated backup server. Currently TSM and

Netbackup are the supported backup applications for this service.

v 7426 (NDMP) - Enables backup applications and NAS devices to perform backup

and restore using the NDMP version 4 protocol over an IP network. With this

enabled the TS7520 acts as an NDMP server, centralizing management while

eliminating locally attached tape devices from each NAS device. When a backup

occurs, data is moved from a NAS device directly to the virtual library.

v 7427 (Secure Tape) - Enables encryption with one or more keys for data

exported to physical tape and decryption when it is imported back to virtual

tapes. The data on the tape cannot be read or be decrypted without using the

appropriate key.

v 7428 (iSCSI) - Enables SCSI commands to be used over an IP network and

allows hosts to connect via ethernet instead of requiring fibre channel. If this




should have this feature installed.

v 7428 (Local Replication) - Enables making a copy of a complete virtual volume

in the same TS7520 server. This acts exactly the same as network replication

except the target and source servers are the same.

v 7430 (Enhanced Tape Caching) - This function is included in the Enterprise

Edition software. Enhanced Caching enhances the functionality of the TS7520 by

acting as a cache to a physical tape library, providing transparent access to data

regardless of its location. With the Enhanced caching option, tapes will always

appear to be inside virtual libraries and will be visible to the backup application

regardless of whether the data is actually on disk or tape. This means that the

backup application will always have direct access to data regardless of whether

the data is on disk or on physical tape.

Note: Two optional adapters can be ordered on the TS7520 Virtualization Engine

Server to provide host, tape and iSCSI connections.

v 3450 - Dual-4Gb/sec FC port card – Used for all fibre channel (FC)

connections. FC 3450 support multi-WWPN mode for failover operations and

FCTAPE profile. FC 3450 can be used for host target FC cards or tape initiator

cards in slots 3-6. Slot placement order: 3, 4, 5, 6.

Note: Slots 1 & 2 will always be filled with FC adapters for disk subsystem

attachment (except in the case of the TS75202 LE (Limited Edition)

product offering, where only 1 slot -- slot #1 – will be used).


v 3451 - Quad-1Gb/sec Ethernet port card - Used for iSCSI and customer

network connections. Ethernet port bonding is supported. Slot placement order:

6, 5, 4, 3.

Note: Up to four cards are available for host connection: any combination of

fibre channel (dual ports) or Ethernet (quad ports). A minimum of one card

is required for host connection. Up to two fibre channel cards (4 ports) can

be dedicated to physical tape connection. Up to two ethernet cards (8

ports) may be used for network replication connections.

“Feature codes for TS7520 Virtualization Engine Server (3954 CV6)” on page 40.

TS7520 Virtualization Engine Server controls

An operator panel, with a button and indicators, is located on the front of the

TS7520 Virtualization Engine Server. The operator panel, located on the lower right

front of the TS7520 Virtualization Engine Server, has the following controls:

v Power-on LED

v Power-control button

v Four indicator LEDs

The Power-on LED is located on the left of the operator panel. When this LED is

off, it indicates that ac power is not present. Approximately 5 seconds after the

TS7520 Virtualization Engine Server is connected to ac power, the Power-on LED is

lit and indicates that the TS7520 Virtualization Engine Server is turned on. When

this LED is flashing, it indicates that the TS7520 Virtualization Engine Server is

turned off but still connected to an ac power source.

To the right of the Power-on LED is the Power-control Button. When the Power-on

LED is lit, the Power-Control Button becomes active, and the TS7520 Virtualization

Engine Server can be turned on and start the operating system by pressing the

Power-Control Button.

Attention: When powering on or off the TS7520, always follow exactly the

power-on and power-off procedures described in the IBM Virtualization Engine for

Tape TS7520 User’s Guide.

To the right of the Power-control Button are four other indicator LEDs that indicate

status or error conditions associated with the TS7520 Virtualization Engine Server.

To the left of the operator panel is a DVD-ROM used for service of the TS7520

Virtualization Engine Server. For a detailed description of the TS7520 Virtualization

Engine Server hardware, controls, and indicators, refer to the IBM Virtualization

Engine TS7500 User’s Guide (GC27-2068).

Advanced features for the TS7520 Virtualization Engine Server (3954

CV6)

The following sections provide additional detail about the following advanced

features available for the TS7520 Virtualization Engine (3954 CV6).

v “Failover/failback”

v “Network replication” on page 51

v “Network encryption” on page 51

v “Network compression” on page 51

v “Secure Tape” on page 52

v “NDMP” on page 52

v “iSCSI” on page 52

v “Hosted Backup” on page 52

v “Control Path Failover and Data Path Failover” on page 52

v “Enhanced Caching” on page 52

v “4-way node support” on page 52

Note: If any of these advanced features are installed in one TS7520 Virtualization

Engine Server in a 3952 Tape Frame, and Failover/Failback will be

configured, and a second TS7520 Virtualization Engine is present in the

3952 Tape Frame, the second TS7520 Virtualization Engine Server must

also have the feature installed.

Failover/failback

Note: Failover is supported for Fibre Channel and SAN/IP only.

To support mission-critical computing, TS7520 Virtualization Engine failover/failback

support provides high availability for the entire storage network, protecting you from

a wide variety of problems, including:

v Storage device path failure

v TS7520 Virtualization Engine Server failure (including storage device failure)

If activated, the failover/failback feature enables active/active failover/failback

without dedicated standby ports. This feature requires two servers.

TS7520 Virtualization Engine supports active-active failover to eliminate single

points of failure. In an active-active configuration, 3954 CV6s monitor each other for

failure conditions. If a failure condition is detected, the functioning 3954 CV6


automatically takes over the resources of the failed 3954 CV6. Resources include

virtual libraries, virtual drives, virtual tapes, client configurations, and so on. Fibre

Channel WWPNs are also moved (spoofed) so that clients are unaware that the

resources have been moved to a different node.

In a failover scenario, the outage time is usually no longer than a few minutes.

If a 3954 CV6 fails, then the second 3954 CV6 takes over the responsibilities of the

failed 3954 CV6 in a transparent manner to maintain continued access to data.

Active jobs may fail when a failover occurs, possibly requiring job restart.

For additional information about the failover/failback feature, see the IBM


Network replication

This involves copying a complete virtual volume from one TS7520 server to another

across an IP network. At prescribed intervals, when the tape is not in use, changed

data from the primary virtual tape is transmitted to the replica resource on the target

server so that they are synchronized. The target server is usually located at a

remote location. Under normal operation, backup clients do not have access to the

replica resource on the target server. If a disaster occurs and the replica is needed,

the administrator can promote the replica to become the primary virtual tape so that

clients can access it.

The network replication feature protects the data on a virtual tape by maintaining a

remote copy of the virtual tape on another TS7520 server accessible over the IP

network. The other remote server may be any distance away, as long as it is

accessible via a network connection.

For additional information about the network replication feature, see the IBM


Network Replication Disaster Recovery Testing Support: This function is

implemented when users are given READ-ONLY access to replica virtual tapes for

testing. This is accomplished through first suspending replication, followed by

testing with the read-only volumes and concluded by resuming replication.

Network encryption

The network encryption feature secures data transmission over the network during

replication. Initial key distribution is accomplished using the authenticated

Diffie-Hellman exchange protocol. Subsequent session keys are derived from the

master shared secret key.

For additional information about the network encryption feature, see the IBM


Network compression

When activated, the network compression feature supports compression of data

that is being replicated to remote TS7520s. Network compression reduces network

traffic and potentially improves the overall performance of network replication.

Network compression is not to be confused with the enablement of software

compression of incoming data prior to being written on the virtual cartridge.

For additional information about the network compression feature, see the IBM



Secure Tape

Uses the Advanced Encryption Standard (AES) algorithm published by the National

Institute of Standards and Technology, an agency of the US government. With this

option, you can create one or more keys that can be used to encrypt the data when

it is exported to physical tape and decrypt when it is imported back to virtual tapes.

The data on the tape cannot be read or be decrypted without using the appropriate

key.

NDMP

The NDMP backup support option allows backup applications and NAS devices to

perform backup and restore using the NDMP version 4 protocol over an IP network.

With this enabled the TS7520 acts as an NDMP server, centralizing management

while eliminating locally attached tape devices from each NAS device. When a

backup occurs, data is moved from a NAS device directly to the virtual library.

Note: This option is not needed when presenting a virtual tape library over FC to a

NAS filer as a replacement for a physical library.

iSCSI

This option allows SCSI commands to be used over an IP network and allows hosts

to connect the ethernet instead of requiring fibre channel. The supported host

platforms are Windows and Linux.

Hosted Backup

The Hosted Backup option makes virtual tape libraries and drives available to local

system by allowing backup applications to be installed directly on to the TS7520,

eliminating the need for a dedicated backup server. Currently TSM and Netbackup

are the supported backup applications for this service.

Control Path Failover and Data Path Failover

Control Path Failover works in the following way: in the event of a loss of a host

adapter or control path virtual drive, the failover mechanism is designed to provide

automatic control path failover to a pre-configured redundant control path without

aborting the current job in progress. The Data Path Failover is designed to provide

a failover mechanism for configuring multiple redundant paths in a SAN

environment. In the event of a path or component failure, the failover mechanism is

designed to automatically provide error recovery to retry the current operation using

an alternate, pre-configured path without aborting the current job in progress. This

can provide flexibility in SAN configuration, availability, and management.

Enhanced Caching

The Enhanced Caching option enhances the functionality of TS7520 by acting as a

cache to a physical tape library, providing transparent access to data regardless of

its location. With the Enhanced caching option, tapes will always appear to be

inside virtual libraries and will be visible to the backup application regardless of

whether the data is actually on disk or tape. This means that the backup application

will always have direct access to data regardless of whether the data is on disk or

on physical tape.

4-way node support

This permits the sharing of all virtual media among all four potential CV6 servers.

Any virtual library’s medium changer and media will be available to any CV6

(subject to the user-specified definitions). CV6s will maintain their own virtual drives

and failover will only be done to a preassigned CV6 housed in the same rack. In

addition, implementation of the virtual pass-through function which permits volumes

to be moved between CV6s via a shared virtual shelf or vault will be performed.


Command Line Interface

Most operations that can be performed via the console GUI can also be performed

through a command line interface. This will allow for scripting of repeatable tasks.

Network Replication Interoperability

Network replication will allow any approved hardware version of the TS7520 running

version 2 release 1 software to have the ability to perform network replication with

any other approved hardware version of the TS7520 running version 2 release 1

software.

iSeries Support

iSeries support similar to that provided via an RPQ for TS7510 will be provided in

this release. In addition to the functionality provided by the RPQ, certain cosmetic

enhancements will be made to make the system more robust.

TS7500 V2R1 Software

The IBM Virtualization Engine TS7500 Software Version 2 Release 1 Enterprise

Edition (5697-N65) and IBM Virtualization Engine TS7500 Software Version 2

Release 1 Limited Edition (5697-N66) provides the software for the IBM

Virtualization Engine TS7520 and the software for a VE Console.

The IBM Virtualization Engine TS7500 Version 2 Release 1 Enterprise Edition

Software (5697-N65) and the Limited Edition Software (5697-N66) have two

components:

v The VE Console program is Java-based. It runs as a client on a customer

supplied VE Console. The VE Console must operate on a Windows® platform

that meets the requirements described in “TS7520 Virtualization Engine VE

Console requirements” on page 71.

v The TS7520 server software runs on the TS7520 Virtualization Engine. One

version of the TS7500 Software V2R1 is needed per engine.

The TS7500 V2R1 Software (5697-N65 or 5697-N66) must be ordered and installed

with each TS7520 Model CV6. This software is preloaded on the TS7520 Model

CV6 by specifying the following feature:

v 9302 (Enterprise Edition VE Preload - AAS) - To have the factory install the

5697-N65 program.

v 9303 (Limited Edition VE Preload - AAS) - To have the factory install the

5697-N66 program.

VE Console and Capacity Support per Terabyte is delivered via capacity tiers

shown on Table 15 on page 54 It delivers the TS7520 VE Console program and

provides entitlement to use the available disk capacity. One of features (0006, 0007,

0008, 0009, 0010, 0011) are required for every 1 TB of storage. Approximately 6.5

units of one of the appropriate capacity tiers are required for every TS7520 Cache

Controller or TS7520 Cache Module allocated to the TS7520 Virtualization Engine

Server applicable to each 5697-N65 license. 18 TB of support are included in each

5697-N66 license. No additional features are necessary to utilize that capacity. For

complete details on the quantity of features (0006, 0007, 0008, 0009, 0010, 0011)

required for your configuration, see Table 17 on page 55.

Feature highlights include support for:

v 128 virtual libraries (3584, TS3310, TS3200, TS3100, 3583 Emulation)

The console program and machine are required to complete the installation of the

TS7520.

A VE Console is used for configuration, management, and service support for the

TS7520 Virtualization Engine. This console is required by the TS7520 and is either

supplied by the customer or optionally can be ordered from IBM. If a VE Console

machine is ordered, it is placed as a separate order from the TS7520. You must

insure the console machine is available and ready to install the console program

before they plan to activate the TS7520. For more details on the console machine

requirements, see “TS7520 Virtualization Engine VE Console requirements” on

page 71.

The Console & Capacity Support feature, must be installed on a customer supplied

VE Console based workstation. See “TS7520 Virtualization Engine VE Console

requirements” on page 71 for the minimum requirements of the Console machine. If

a platform with the proper configuration is not currently available, one will need to

be ordered.

Note: The ’per server’ features of the program may only be installed on a TS7520

Virtualization Engine, or subsequent IBM replacements of the TS7520

Virtualization Engine. These features will be preloaded on each new TS7520

Virtualization Engine manufactured.

If any of the following optional hardware features on the TS7520 Virtualization

Engine Server (3954 CV6) are ordered and installed, then specific corequisite

software features must also be ordered and installed as described below. Hardware

features that enable advanced functions must be installed by the IBM Service

Chapter 4. Sizing, configuration, and usage considerations

This chapter addresses some of the key challenges in determining an appropriate

match of the TS7520 Virtualization Engine to your needs and provides aid in setting

appropriate expectations both for functional capabilities and performance. This

chapter addresses:

v Basic configuration recommendations for a TS7520

v Sizing considerations to help determine how many TS7520s may be required to

fit your needs

v Impact of associated system components

v Specific advanced features and their role in fulfilling your shop’s data protection

requirements

v System-level implications of designing a data protection architecture around

various usage modes for the TS7520

Default library configuration

Shipped from the factory, you can order the TS7520 single TS7520 Virtualization

Engine Server (3954 CV6) configuration in either the Limited Edition configuration

or the Enterprise Edition configuration. With the Enterprise Edition, you also have

the option of a failover configuration (two TS7520 Virtualization Engine Servers) or

dual failover pairs in a four node system (two TS7520 Virtualization Engine Servers

in the first-base frame and two TS7520 Virtualization Engine Servers in the second

space frame). In a single-server configuration, all available disk storage is allocated

to the one virtualization server, while in a failover or four node configuration, the

disk storage is split evenly between all virtualization servers.

Each TS7520 Cache Controller (3955 SV6) or TS7520 Cache Module (3955 SX6) is

split into multiple logical disk drives; either all logical drives are allocated (or

″enlisted″) for the single virtualization server or, on a per disk drawer basis,

individual logical drives are enlisted for any of the other virtualization servers

present in the system. Every disk drawer in every frame has one spare SATA drive,

which may be used by any logical drive in the disk subsystem controlled by a given

virtualization server. A typical 3955 SV6 or 3955 SX6 disk drawer yields two RAID 5

groups (one 7 disk and one 8 disk). With RAID 5 protection and the 500GB drive

capacity and one hot spare, the 7 disk group yields two 1.43 TB logical drives and

the 8 disk group yields two 1.67 TB logical drives.

The default configuration is determined when the TS7520 system is built and the

manufacturing decision is made whether it is to be a failover or non-failover system.

In the default configuration, the following applies for each virtualization server. Two

default libraries are present:

v Each virtual library is a virtual 3584 frame and twelve virtual LTO 2 drives are

defined.

v Based on the available disk storage enlisted, the maximum quantity of virtual

200GB LTO 2 cartridges that could be created in the available space is defined.

v Volumes are created with a default labeling convention:

– VEOOOOL2, ... , VEOOOnL2 for the first library (accessible on the card in

PCI slot 3, port 1 assuming the card is present)

– VE1000L2 , ... , VE100nL2 for the second library (accessible on the card in

PCI slot 4, port 1 assuming the card is present)


v No LUN masking is active and all attached initiators have access to all virtual

resources.

v Each virtual library is configured with 253 virtual cartridge slots.

In the case of a field installation of a second virtualization server in an existing

frame, the disk logical drive (LUN) enlistment and the definition of virtual libraries,

drives and libraries will not occur by default; it must be specified by the user. The

system administrator must take care to understand how available (free) disk LUN

space is to be allocated; the factory defaults of 50/50 splits between the two

virtualization servers will no longer apply in this case. Special care must also be

taken when an additional base frame is added to the system because all of disk

storage must be seen by all four nodes of the system.

Note: You can override the factory defaults of space allocation, even for

factory-built failover configurations.

Variations on the configuration defaults

Configured in this manner on start up, the TS7520 is immediately usable, even

without the attachment of the Management Console GUI. Nevertheless, the

expectation is that most customers will want to customize their configuration. This

can be done by adding more virtual volumes or drives.

Space is only allocated from the disk pool as needed, so if a particular volume will

only require 10GB, for example, rather than 200GB, 10GB is all that is actually

used from the disk pool. As a result, you may have many more 200GB virtual

volumes defined than you have physical disk space to accommodate. In addition, if

you want to force an end-of-volume condition early (for example, you may want a

volume to fill up at 2GB), you simply define the volume capacity to be whatever you

want it to be.

You can also define a volume’s capacity to artificially large, up to 1024 GB. As with

physical tape, you have the option of turning on compression for greater space

efficiency, but compression results in lowered bandwidth performance.

Many other options are available as well, including:

v Defining additional virtual libraries

v Changing the LUN masking, to defining different kinds of virtual drives

v Defining different volume replication and archive policies

v Enabling enhanced caching

These options are discussed further in this chapter.

Basic configuration recommendations

The default library configuration does not suit all customers’ needs. It is only a

starting point to permit immediate usability.

A good understanding of your environment, including attached hosts and

connectivity, applications, workloads, and service level requirements, can result in

the basis for more tailored planning to permit the best configuration and usage of

your TS7520s. The following sections discuss some basics relating to connectivity

and base library definition. You have the option at the outset of deleting all default

configurations and redefining configurations to exactly meet your needs.


HBA target mode and initiator mode

Depending on the number of additional fibre Channel cards (up to four), each

TS7520 server can provide up to four 4Gb fibre channel ports for host attachment

and up to four 4Gb fibre channel ports for physical tape attachment. The most basic

decision to make about the TS7520 setup is whether you want to have direct

physical tape attachment to exploit features such as auto-archive (physical tape

copy on export) and enhanced caching, or whether you want all physical tape

production to be fully managed by the ISV applications driving the TS7520.

In the latter case, which provides the greatest control, the physical tape is not

attached to the TS7520 but is attached to the host fabric in parallel with the

TS7520. In this case, a TS7520 provides up to four ports for host fibre channel

attachment. The use of three or four ports for host I/O can enable the TS7520 with

higher bandwidths than what can be achieved through two ports. Sustained rates

well in excess of 1200 MB/second have been measured in this configuration, even

with a single TS7520 Virtualization Engine Server (3954 CV6) attached to two

TS7520 Cache Controllers (3955 SV6s), each with three TS7520 Cache Module

(3955 SX6s). The TS7520 Management Console provides the means to change any

of the remaining ports from initiator mode (driving physical tape) to target mode

(accepting host commands).

Zoning and LUN masking

Library control path and drive data path failover is currently supported for the

TS7520 Virtualization Engine as a chargeable feature. This allows for multiple host

connections to the TS7520 and correspondingly primary and alternate paths and

drives as seen from the host. When control path and data path failover are not

configured, the best management of pathing where hosts are attaching through a

SAN fabric results in a zoning configuration in which each host-port-to-TS7520-port

connection is isolated in its own zone.

Note: Zoning is defined and managed at the Graphical User Interface (GUI)

provided for controlling a switch fabric; it is not under the control of the

TS7520.

Either hard or soft zoning may be used in the case of a single TS7520 3954 CV6.

In the case of a dual TS7520 3954 CV6 (failover) configuration or four node (dual

failover pairs), soft-zoning provides the greatest simplicity and flexibility. In the

failover case, you must ensure physical (fabric) connectivity of the host fibre

channel port to both the fibre channel port of the primary virtualization server

(where the virtual library of interest is defined) and to the corresponding fibre

channel port of the secondary virtualization server. Because nodes cannot failover

between frames (a four node system is actually two failover pairs), it is not

necessary to ensure physical connectivity from the host fibre Channel ports

connected to nodes in one frame to those of another frame.

After physical connectivity is ensured for failover partners in the same frame, the

soft-zone only needs to specify the World-Wide Port Name (WWPN) of the host

(initiator) port and the primary virtualization server (target) port. On failover, the

WWPN identity of the failing virtualization server is shifted to the surviving failover

partner (the secondary virtualization server in the same frame). Alternatively, if your

switch fabric only supports hard zoning, then your zone needs to include the switch

port to which the host is connected, as well as the switch port to which the primary

virtualization-server-participating port is connected and the switch port to which the

secondary virtualization-server-corresponding switch port is connected.

Chapter 4. Sizing, configuration, and usage considerations 59

In a complex environment, many zones will overlap (each host port may be a

member of multiple zones and each TS7520 port will be a member of multiple

zones), so greater control may be achieved by the use of LUN masking (also

known as LUN mapping) using the TS7520 Management Console. Without LUN

masking defined, every virtual device accessible via a TS7520 port is visible to

every host initiator attaching that port. With LUN masking , you can make certain

virtual devices invisible to some hosts. By this means, you can effectively dedicate

certain virtual drives and/or libraries to certain applications and achieve some level

of static load balancing as well.

Virtual libraries: Sharing and capacity planning overview

The following topics discuss sharing and capacity planning for virtual libraries.

Determining numbers of virtual libraries and virtual drives

At the minimum, the sharing of a virtual library permits shared access to the virtual

volume data, whether or not specific virtual drives are shared or the systems

sharing the virtual volumes use disjoint sets of virtual drives. Sometimes there is a

need to share a virtual library across applications. Usually, however, a single virtual

library is dedicated to the use of a single application, even if multiple hosts connect

to the same library. Some applications might manage sharing of (virtual) drives

across hosts, and while the TS7520 does support multi-host sharing of virtual

drives, this is not necessary for sharing the virtual volume data.

As a starting point then, one can determine the number of unique virtual libraries to

be created based on sets of distinct applications or application-business unit

combinations to be supported, where the key is determining the boundaries of the

need to share data.

For example:

Three distinct business units use application A, but want their data managed

separately with no possibility of the data from one unit being accessible by another.

At the same time, all three business units share data managed or created by

application B. In this example, it is recommended to create four distinct virtual

libraries.

v Three libraries would be created for hosting application A, with each library

uniquely holding the data relating to one of the three business units.

v One library would be created for hosting application B, with the library holding the

shared data relating to all three of the business units (or data for which common

management posed no business risk). Application B might be sufficiently

sophisticated to support management of shared virtual drives within the shared

library as well, but more basic applications might not, in which case it would be

prudent to define three distinct groups of virtual drives, each with appropriate

LUN masking defined to limit their visibility to just a single attaching host. In other

cases, such as in some LAN-free client access environments, it might be

desirable to support having an application server mount and label virtual

cartridges, whereupon an application client may begin direct-writing to the

cartridge, favoring the support of shared virtual drives.

The maximum number of virtual drives to define within a virtual library in a TS7520

depends on both the maximum number of concurrently mounted volumes any user

job requires and the maximum number of user jobs that can be supported at one


time. This latter factor will be determined by knowing what average bandwidth a

given job can sustain (if not tape-limited) and must sustain to meet its service level

requirements.

If, at most, N user jobs must be run simultaneously and user job j (where j = 1, ...,

N) uses a maximum of d(j) drives simultaneously, each at a data rate r(j,i) (where

i=1, ..., d(j)), the aggregate bandwidth demand of these is:

Bandwidth Demand = Sumj = 1, ..., N

(Sumi = 1, ..., d(j)

r(j,i))

For a single virtualization server (3954 CV6) with only two host fibre channel ports,

the Bandwidth Demand should be configured to be less than 900 MB/second, which

is less than the 1000MB/second the two ports can sustain. This is a very rough rule

of thumb, based on the notion that an aggregate bandwidth demand may vary, and

that one should accommodate peaks that can exceed the average in order to avoid

exceeding service level agreements for job run times.

Note: While this discussion was carried out in the context of a single virtual library,

the logic applies equally to the aggregate of virtual drives in all virtual

libraries defined within a single virtualization server (3954 CV6).

If four ports are available for host connection on a single virtualization server (3954

CV6), then the top bandwidth for the 3954 CV6 will be closer to 1200MB/second,

with 1100 MB/second being a prudent target . Achievable bandwidths,

unconstrained by other system factors, will vary as a function of application block

sizes used, whether or not compression is active, and whether or not other

functions are in use (such as network replication, network encryption, and

compression). You may notice that the top bandwidth for four fibre Channel ports is

not double that of two fibre Channel ports connected to hosts. This is because at

this rate, the virtualization server is not the limiter; the limiter instead is the

sustainable SV6 bandwidth.

Because each 3954 CV6 virtualization server accesses a different SV6, the total

maximum bandwidth is a multiple of the maximum bandwidth obtainable from a

single 3954 CV6 virtualization server. This means that with two TS7520 3954 CV6

virtualization servers, the maximum bandwidth would be 2400MB/second and with

four virtualization servers would be 4800MB/second.

One more important item to note is that if the TS7500 V2R1 software is installed on

TS7510 3954 CV5 servers, the bandwidth will be limited to half of what it is with the

TS7520 3954 CV6 servers because 2 Gb fibre Channel ports are used instead of

the new, 4 Gb fibre Channel ports.

iSCSI considerations

With the TS7500 V2R1 software comes the ability to use iSCSI and ethernet ports

for host attachment. The TS7520 has the ability to contain up to four Quad port Gb

ethernet cards which when combined with the two planar Gb ethernet ports

provides a maximum of 18 Gb ethernet ports that can be used for possible iSCSI

host connection. This may seem unwieldy, but with the port bonding available for all

ethernet ports in a given machine running TS7500 V2R1 software, any combination

of bonded ports can be used to reduce the number of actual IP addresses that are

required. The maximum throughput of a single ethernet port is 125 MB/second, but

with the iSCSI protocol comes overhead and the actual maximum throughput is

approximately 87 MB/second. We recommend using 75 MB/second as a good rule

of thumb. With this figure it would take 14 of the gigabit ethernet ports to be bonded


together to equal the approximate throughput of two of the fiber Channel ports. This

also means that it would take more than 16 Gb ethernet ports bonded together to

begin to saturate the 1200 MB/second sustainable bandwidth on the attached disk

cache.

Virtual libraries and physical libraries: Differences in capacity planning

Capacity planning in a virtual library environment and a physical library environment

have similarities, but also significant differences. In both cases, knowledge of

workloads forms the basis of good planning. The following describes the

characteristic differences between the two environments:

v Accessors

– Physical libraries have a limited number (usually one or two) of cartridge

accessors (or ″robots″) to mount tape cartridges. These accessors take at

least several seconds to pick and mount cartridges. Mounts can queue waiting

on this resource.

– Virtual libraries have virtual accessors which logically mount virtual cartridges

in milliseconds (at most). Queuing on the accessor is essentially non-existent.

v Load/unload and locate times

– Physical drives will have load and unload times that can vary from 5 to 20

seconds (or more) on load to over a minute on unload . Locate times can

match maximum unload times.

– Virtual drives will have virtual load and unload times which take milliseconds

(at most). Locate times are similar.

v Read/write times

– Physical drives can have worst-case read or write times (in error retry

scenarios with repositioning and wrap refreshing) that can exceed 20 or 30

minutes.

– Virtual drives have no counterpart to long read or write times. Even error

recovery scenarios typically run at most a few seconds.

v Aggregate bandwidth

– Aggregate bandwidth for physical libraries scales linearly with the number of

available drives. The limiters will be other system elements (such as logical

job structure, disk I/O, fabric limitations, and other contending I/O on the

hosts’ fibre channel adapters).

– Aggregate bandwidth for virtual libraries scales semi-linearly (with increasing

numbers of active drives) only up to a point of virtual library subsystem

saturation. At that point, increasing the number of active drives has no impact

on overall aggregate bandwidth, and the maximum per-drive bandwidth begins

to drop in proportion to the total number of active drives.

v Capacity

– Physical cartridges have a fixed capacity, which is determined at the time of

purchase (subject to the potential compressibility of the data written to them).

A given physical library’s ultimate capacity is strictly determined by available

slots, cartridge capacity, and data compressibility. For most open systems not

storing totally random data, compressibility is roughly 2:1 for typical drive

compression algorithms. Individual drive bandwidth is the usually the same

whether compression is active or not. Unused cartridge capacity is wasted .

– Virtual cartridges may be defined with any desired capacity, from very small

capacities that may be less than 1% of the native capacity of the specified

emulated media type, to very large capacities (up to 1024GB in the case of

the TS7520). Virtual slots may be added as desired to support more virtual

cartridges. With capacity-on-demand allocation, unused virtual cartridge


capacity wastes little or no underlying disk space. Virtual library data

compression, on the other hand, typically slows down effective single drive

data rates significantly, even though it expands effective library capacity.

Virtual libraries and physical libraries: Similarities in capacity planning

The basic determination of capacity requirements (total terabytes of data) for a

library are effectively the same for physical and virtual libraries. In the case of

backup data, capacity depends on the number of generations of backup data to be

held, the size of the disk systems being backed up, and the relative use of full

backups as opposed to incremental or differential backups. For a given host,

consider the size of data to be backed up and the average amount of data changed

per day (or backup period).

For example:

An organization has 400 GB of customer data and 5% of that data is changed each

day. A full backup requires 400 GB. A daily incremental backup requires 20 GB. If

two weeks of data is to be kept, the total data is: 2x400 GB plus 6x20 GB = 920

GB (assuming the organization does not need incremental backups from two weeks

ago). If the application supports differential or cumulative backups, this number may

be less. Consider each application and the different hosts involved. Sum over the

set of hosts and applications to be backed up. For the TS7520, keep the total

capacity under 832 TB for a single or dual virtualization server(s) (3954 CV6) and

under 884 TB for a 4 node/server system. If expected bandwidth to achieve backup

window exceeds the capacity of the TS7520, then reduce the number of hosts or

reschedule backups so they do not all overlap. It should be noted that the 832 TB

maximum capacity for a single or dual virtualization server configuration consists of

a full base frame of storage and 10 expansion frames, which although it is possible

may not be practical performance wise. It is recommended that if 10 expansion

frames are going to be used, that a four node/server system be used as well.

Virtual volume space allocation schemes and disk LUN enlistment

Unless you are concerned about virtual media which is expected to fill completely to

capacity in all cases, choose capacity-on-demand (the default if no choice is made)

to control disk space allocation to virtual tape volumes. The capacity-on-demand

scheme allocates only 5-GB segments at a time, with the first segment not

allocated until the tape is first mounted and written. While this may not afford the

optimal sequential read or write performance with the disk cache, the segment size

is sufficiently large that performance will not be significantly degraded and space

management will be optimal (with fixed segment sizes). You have the option of

overriding the default allocation scheme.

Except where you are converting an existing TS7520 to a 2 node or 4 node

configuration, you should allow the virtualization server (3954 CV6) to manage the

disk LUN enlistment. This results in better I/O balance and performance. In general,

if virtualization servers with significantly different workload aggregate bandwidth

demands run any single 3954 CV6 to near-saturation, this may suggest a need to

rebalance if service level commitments are not being met.

The practical implementation of a rebalancing between 3954 CV6s involves the

creation of a new virtual library on the lightly loaded 3954 CV6. The implementation

also involves the copying of the virtual volumes from the original virtual library to the

new one under ISV application control to maintain application awareness of data

location.


Additional capacity planning considerations

The following summarizes additional capacity planning considerations:

v Failover impacts

When failover is enabled, all capacity and virtual resources will fail over. In this

case a single virtualization server (3954 CV6) handles the workload normally

handled by two virtualization servers. Jobs in heavily loaded environments may

experience elongation during the failover period. Be sure that performance is

tolerable in failover state. Check the guidance in this chapter and

application-specific performance as further guidance becomes available in

whitepapers.

v Network replication impacts

Reserve space for the replica resource area for all cases where a TS7520 will be

a target of network replication from a remote TS7520. The replica resource area

directly detracts from the available space for local libraries’ virtual cartridges.

v Virtual Vault residency impacts

Reserve space for the virtual vault (or virtual ″shelf″) for auto-archive operations

(physical tape copy on export) or others (such as manual copy) where tapes are

temporarily moved to the virtual vault prior to copying. This is especially

important if you are running in copy mode rather than move mode, or if you are

running in move mode with a long grace period prior to deletion. The virtual vault

area directly detracts from the available space for local libraries’ virtual

cartridges.

v Access density considerations

Use the size of the available backup window to calculate the data rate required

to support it. If the rate cannot be supported by the TS7520, then split the

backup task into multiple components, reducing the single-threaded

characteristics either on the application host side (breaking into tasks for multiple

hosts) or on the target side (breaking into multiple backup streams targeting

different volumes simultaneously), or both.

v Compression considerations

Determine if you are space-constrained or backup-window-constrained. If you do

not have backup window constraints, then consider enabling 3954 CV6

compression. Performance can significantly drop with use of 3954 CV6

compression, especially with relatively incompressible data.

v Tape attachment or tapeless 3954 CV6

Use of the auto-archive (physical tape copy on export) or enhanced caching

function reduces the load on the application backup server but has no effect on

the 3954 CV6 (reading data from the 3954 CV6 for external copy to a physical

tape drive via the backup server as opposed to having the 3954 CV6 do the

writing to the external physical tape drive locally attached to it using the

auto-archive or enhanced caching function).

v Concurrent stream aggregation

Each virtual drive can be allocated to a specific host application stream. Virtual

media can be appropriately sized for capacity and later aggregated to real media

in an external copy operation.

System application and advanced function considerations

Virtual tape disk-based systems have a number of advantages over disk targets for

backup:


v Tape targets are nearly universally supported by backup applications and disk

targets are not. This works well even among disparate host types attaching the

virtual library in a SAN.

v Sharing of tape data requires only a mount of a virtual cartridge in a common

virtual library. Sharing of disk data requires a shared file system. Shared SAN file

systems are still not widely deployed and are relatively difficult to set up.

v Tape targets have underlying simple structures with very low overhead on

attaching backup servers. Virtual tape targets eliminate any performance delays

that real tape targets have relative to disk targets.

v Disk targets require file system support on the attaching backup servers with

significantly higher performance overhead. They have no speed advantage over

virtual tape targets.

The following sections examine some environments of particular interest to better

understand how they are configured and what motivates their use.

Tape SAN exploitation: LAN-free backup/restore

LAN-free backup/restore is a configuration most widely supported by tape products

with significant performance advantages. The idea of LAN-free backup is that a

backup server manages the assignment of a drive and tape volume to a given client

backup task, but the data I/O occurs directly from the client to the backup medium

(typically over the SAN, rather than via the LAN through the backup server). This

reduces network traffic and backup server load. Large data object performance is

significantly improved.

Tape LAN-free backup is much more widely supported than disk LAN-free (which

requires a shared file system). The TS7520 supports LAN-free backup as readily as

physical tape but with potentially superior performance because the TS7520 has

none of the mount queue, load, or locate overheads of physical tape.

Figure 7 on page 66 illustrates traditional backup over a LAN to a backup server

which connects via a SAN to a tape library.


Figure 8 illustrates LAN-free backup directly from clients over the SAN to a tape

library.

TS7520-parallel and TS7520-inline attachment of physical tape

Physical tape can be used in a TS7520 environment in two distinct ways: it can be

directly attached to the backup server and fully managed by the ISV backup

application, or it can be attached to the TS7520 fibre channel ports with modes of

use that are either tied indirectly to ISV backup application management or that are

not managed by the ISV application at all. In general, IBM does not recommend

usage modes that are not managed by the primary backup application or that are

not managed by a customer tape media management system. Such usages must

be manually tracked and managed, and are generally only appropriate to exploit in

exceptional situations. For the current offering, physical tape attachment to the ISV

backup server directly (that is, in parallel to the TS7520) may be a better choice for

many installations where full management of physical media in all situations is

mandatory.

An example of a parallel-attachment configuration would be the use of TSM-based

duplication using copy pools. Here, the TS7520 would be a primary backup target

of a TSM server (possibly also accessible to TSM clients in a LAN-free

SAN-attached environment). A separate physical tape library would also be

connected to the TSM server via the SAN, where some set of cartridges in the

physical tape library would be part of TSM Copy Pool. Writing to the physical tape

would occur as a result of the TSM server copying the TS7520 data into the

physical cartridges. The following characteristics apply in this situation:

v The parallel approach has the advantage of supporting incremental backup of

storage pool data, permitting the physical cartridges as well as the virtual

cartridges to stay resident in their libraries. With direct tape attachment, the copy

to physical tape only occurs if the virtual tape (and the physical tape) are

exported from the library, or if the enhanced caching policy for data migration is

triggered.

v In the parallel approach, the primary (virtual) and duplicate (real) volumes can

have different media types, device types, and device capacities, all of which are

tracked by the backup (TSM) server. With virtual auto-archive, real and virtual

media types, device types, and media labels must match exactly.

v Real copies can be made synchronously (during primary creation) or

asynchronously (after primary creation). With auto-archive, the real copy can only

be made after the original copy is created (asynchronous only), but auto-archive

reduces I/O burden on the backup server.

v Physical tape drives and cartridges attached to the TS7520 must be in a partition

not visible to the backup application (in a medium changer library). Libraries such

as the IBM 3494 are accessed by special library manager commands that relieve

some of these constraints.

v Virtual volumes and real volumes may be managed with different policies (such

as retention periods) in the parallel attachment method. With the inline

attachment method, management policies must be identical between virtual and

real volumes.

On the other hand, the creation of physical tape inline attachment with the TS7520

via the auto-archive (physical tape copy on export) can be considered to be fully

managed. When the backup application exports a (virtual) tape (via a Move Medium

to Virtual I/O Slot command), the virtual medium is moved to the virtual vault (out of

the virtual library) and then it is copied to a physical volume of the same media type

and label. The physical volume is then exported from the physical library. From a

backup application point of view, the exported physical volume is known and

outside of any library, as would be expected. The weakness of this model is that it


requires the export of the volume to create a physical copy. Re-entry of the virtual

volume into the virtual library requires operator intervention at the TS7520 VE

Console.

v Enhanced caching considerations

One advantage of the inline method is the backup application’s ability to take

advantage of the enhanced caching that is available through the TS7520. With

enhanced caching, the backup application writes and reads data to and from

virtual libraries in the TS7520 as it would normally. The difference, however, is

that caching policies can be set on the TS7520 that define when to migrate data

out of disk cache and onto physical tape contained within an attached physical

library. In this sense, the virtual tape library acts more like a virtual tape server.

When the data has been migrated from disk and onto physical tape, and when

the cache has been reclaimed, the TS7520’s virtual pass through ability allows

the backup application to interact directly with the physical tape without having to

read the data back into the disk cache.

v NDMP considerations

One way to alleviate a backup application’s inability to track changes performed

by the TS7520 with attached, in-line tape is through NDMP. With NDMP, the

backup application has a connection to an NDMP server running on the TS7520

virtualization engine and knows the state of each volume contained within each

library.

The inline method also defines one means by which the data under a TS7520 can

be protected. Other modes of copy and protection of TS7520 data, which are more

flexible, are those which involve replication across the network.

TS7520 network replication key modes and considerations

The TS7520 supports two primary modes of network replication of virtual volume

data between TS7520s. Note that replication occurs over IP links and may involve

transcontinental distances. With the TS7520, up to 10 1Gb Ethernet ports are

available for replication (two planar ports and 8 available through two Quad Port

ethernet cards). Usage of the ports for a given replication task is determined by

what remote TS7520s are visible to a given port. Two modes are supported:

v Network Replication

A virtual volume may be configured for ongoing replication to a remote 3954 CV6

target’s replica resource space. In this configuration, any changes to a given

local volume are reflected to the remote image according to policy (as driven by

time driver or changed data). Network compression to reduce network load may

be specified if licensed, and network encryption to protect data transfer may be

specified if licensed. A replicated volume can only be recalled (or remote-copied)

after it has been promoted into a remote virtual library from the remote replica

resource space. Each virtual volume may have a different target remote 3954

CV6.

Note: Replica resource space takes away from available virtual volume space

within virtual libraries.

v Network auto-replication (virtual tape copy on export)

A virtual volume may be configured for auto-replication to a given remote 3954

CV6 virtual library (not a replica resource). In this mode, a virtual volume is

moved to the virtual vault and copied not to a physical volume (as with

auto-archive) but to a virtual volume. In this mode, the virtual volume is normally

not exported remotely. Each virtual volume may have a different target remote

3954 CV6.


v Local replication

In addition to the two network replication methods, TS7500 V2R1 provides local

replication as well. With local replication, instead of the remote copy of a

replicated volume being hosted on another server, the copy of the virtual volume

is placed and in other disk LUN accessible from the local server. This provides

the duplication of data but at much faster access speeds than network replication

because it is accessible through the local fibre channel connections.

Failover/failback considerations

Failover/failback can have different application level manifestations. In general, a

failover/failback occurrence appears similar to what would be seen if a host fibre

cable attachment to the tape subsystem was pulled and then later reattached. In

the case of Veritas NetBackup, there is transparent retry of the I/0 in progress, so

NetBackup may normally not require any restart. Failover and failback will be

transparent to it. TSM, on the other hand, may require a task restart (after failure of

the active task) with recovery going back to the last successful synchronization

point on the medium, but the whole TSM region will not be abended and the TSM

server will not require reboot.

Other failoverlfailback behavioral considerations include:

v Failback is as disruptive as failover, except that failback provides the option of

planning its timing to minimize job interruption. Failover for the purpose of system

maintenance, for example, may also be scheduled and manually initiated.

v Failover/failback requires loop mode switch port attachment.

v Failover/failback is not supported for active/passive mode. It is expected that any

failover pair will have primary storage for each 3954 CV6, even if it not perfectly

balanced, as would be the case with a field upgrade to a failover configuration.



Chapter 5. Customer installation responsibilities

Customers are responsible for preparing the installation site, as described in

Chapter 2, “Physical planning specifications for the TS7520,” on page 19, prior to

the installation of the TS7520 Virtualization Engine.

All physical planning for the TS7520 is a customer responsibility. In summary,

customers are responsible for providing network connections (cables and switches),

physical tape libraries, SNMP servers, e-mail servers, host clients, and e-mail

services for Call Home and RSA alerts. Customers must provide IBM with all

necessary IP addresses for the installation of the TS7520.

Customers are responsible for obtaining a VE Console system and for obtaining the

appropriate adapters and cables. Fibre Channel cables are required to attach the

TS7520 to various server adapters. Ethernet cables are required to attach the

TS7520 to iSCSI hosts. Refer to Chapter 3, “TS7520 components and feature

codes,” on page 27 for a list of cables for the attachment of the TS7520

Virtualization Engine. In addition, customers are also responsible for providing client

machines and required Fibre Channel and Ethernet switches as described in the

following sections.

System responsibilities

In addition to meeting the requirements set out in Chapter 2, “Physical planning

specifications for the TS7520,” on page 19, the customer must provide the following

hardware and systems.

TS7520 Virtualization Engine VE Console requirements

The TS7520 Virtualization Engine VE Console system (hereafter called the VE

Console) hosts the IBM Virtualization Engine TS7500 Software Version 2 Release

1. Using the supplied VE Console CD, the customer can install the VE Console

software. IBM recommends that the TS7500 V2R1 Software be installed on the VE

Console prior to the installation of the TS7520 Virtualization Engine.

Note: The license keys required for TS7520 Virtualization Engine feature

enablement require that the TS7500 V2R1 Software for the TS7520 VE

Console be installed and functional before any TS7520 Virtualization Engine

features can be enabled.

The VE Console is used for configuration, management, and service support for the

TS7520. This console is required by the TS7520 and is either supplied by the

customer or optionally ordered from IBM. If a VE Console is ordered, it is placed as

a separate order from the TS7520.

Any general purpose computer meeting the specified hardware and software

requirements may be used for the VE Console. The minimum requirements for the

VE Console are:

v Hardware requirements:

– x86 (Pentium® or higher) microprocessor

– 512 MB memory

– 175 MB of disk space for Virtualization Engine for Tape Console Function and

Capacity Support

– Keyboard, mouse, and CD-ROM drive


– Super VGA monitor with the screen resolution set to at least 800 x 600, small

fonts setting, and 256 colors

– One Ethernet port for attachment to the TS7520 management network

– One additional Ethernet port recommended for Internet access

– A Web browser and Java-2 JRE installed

v Operating environments supported:

– Windows 2000 with Service Pack 4 (SP4)

– Windows 2000 Server SP4

– Windows 2000 Advanced Server SP4

– Windows 2000 Datacenter Server SP4

– Windows 2003 Server Enterprise Edition

– Windows 2003 Datacenter Edition

– Windows XP

At least one VE Console must be installed within line of sight of the TS7520 3592

Hardware, cabling, and infrastructure responsibilities

In general, you are responsible for providing the appropriate infrastructure

resources, such as cables and switches, required to support TS7520 Virtualization

Engine connections to the VE Console, host devices, tape devices.

The following description of the TS7520 Virtualization Engine Server 3954 CV6 will

help in clarifying many of the specific connections to be made to support TS7520

operation.

Four fibre channel ports on each TS7520 Virtualization Engine Server 3954 CV6

are reserved for internal connection between the 3954 CV6 and the TS7520 Cache

Controllers (3955 SV6s). An aggregate of up to eight fibre channel ports are

available for attaching customer backup servers (or backup clients) and customer

physical tape drives.

Note: In target mode, the ports cannot attach physical tape.

Figure 9 on page 75 shows the relationship of each of the physical fibre channel

ports on the QLogic PCI adapter cards, their default usage assignments, and the

logical adapter number (also known as the TS7520 Virtualization Engine VE

Console adapter number) that is assigned to each physical port (as shown in the

VE Console display). Each PCI fibre channel card will have two logical adapters

associated with it, one for each physical fibre channel port. Ports on each PCI card

are numbered left to right (looking at them from the back of the 3954 CV6) as port

1 and port 2. The PCI slots (and the cards that occupy them) on the right side of

the rear of the 3954 CV6 are numbered PCI slot 3 (on top) and PCI slot 4 (on the

bottom). The PCI slots on the left are numbered PCI slot 1 (on top) and PCI slot 2

(on the bottom). Numbering of logical adapters begins with physical ports on the

card in PCI slot 3, then PCI slot 4, then PCI slot 1, and then PCI slot 2.

Table 18 on page 74 summarizes the relationships of VE Console-reported logical

adapters, physical fibre channel ports on the 3954 CV6, and actual usages. In the

cells that contain both an SV6 assignment as well as a switch assignment, the top

assignment is in the case of a single frame system configuration, and the bottom

assignment is the fiber channel switch and port number that would be used in the

case of a multi-frame system. Only adapters from the first four slots are shown

because those are the only adapters that have default target or initiator

assignments. If fibre channel cards are added to the last two slots, those are totally

user configurable.

Ethernet 1 and Ethernet 2 ports carry both the inter-server health monitoring pulse,

replication traffic, call-home traffic, SNMP traps, and management control

information. Both of these physical Ethernet interfaces will carry two IP addresses

(in a failover configuration): one for the health monitoring traffic and one for all other

functions. The RSA Ethernet port carries SNMP traps for the base 3954 CV6 server

service events and provides a port for Service login for field problem resolution.


Notes:

1. The TS7520 Virtualization Engine configuration steps in some documentation

may refer to ethernet 1 and ethernet 2 as eth0 and eth1. Other documentation

may also indirectly refer to ports 1 and 2 of each fibre channel card as ports 0

and 1. Cards are actually stamped with 1 and 2, which is the preferred naming

convention.

2. Do not change the fibre channel adapters or move the cables in PCI slots 1 and

2. The only portion of the TS7520 cabling that is configurable is the attachments

to PCI slots 3 through 6.

3. The RS485, USB and serial ports are not used for the TS7520. They may be

ignored.

The user must provide the following hardware and cabling resources prior to the

installation of the TS7520 Virtualization Engine.

v Ethernet cables for connecting the TS7520 Virtualization Engine to the VE

Console and iSCSI clients

v Fibre channel cables for connecting the TS7520 Virtualization Engine to the hosts

and tape devices or libraries

v VE Console system, as described in “TS7520 Virtualization Engine VE Console

requirements” on page 71

Note: Any user switches, client host platforms, physical tape libraries, tape drives

or tape media the user may require, has to be provided by the user and

should be secured prior to the installation of the TS7520 Virtualization

Engine.

Security, auditability, and control

This product uses the security and auditability features of host hardware, host

software, and/or application software to which it is attached. The customer is

responsible for evaluation, selection, and implementation of security features,

administrative procedures, and appropriate controls in application systems and

communications facilities.

Zoning overview

You can establish zones for fibre-channel attachments to the TS7520. The zones

must contain a single port that is attached to a system adapter with the desired

number of ports that are attached to the TS7520. By establishing zones, you reduce

the possibility of interactions between system adapters in switched configurations.

You can configure switch ports that are attached to the TS7520 in more than one

zone. This enables multiple system adapters to share access to the TS7520

fibre-channel ports. Shared access to a TS7520 fibre-channel port might come from

host platforms that support a combination of bus adapter types and the operating

systems.

Zoning is configured by the user interface provided by your switch fabric. You can

establish the zones by using either of two zoning methods:

v Port number (hard zoning)

Hard zoning is zoning using the port numbers of the switches. This is usually

more tedious to maintain.

v Worldwide port name (WWPN) (soft zoning)

Soft zoning uses the WWPNs in the configuration. The WWPNs will remain the

same in the zoning configuration regardless of the port location.

IBM recommends soft zoning because it minimizes the number of zones needed in

a failover setup and it simplifies port assignment on the switch.

Attention: IBM strongly recommends setting up individual zones for each host

initiator HBA port and TS7520 HBA port connection that is to be supported.

v If soft-zoning is used, the zone may specify the WWPN of the host HBA port and

the HBA port of the primary 3954 CV6 containing the virtual libraries during good

(not failed over) operation. In the case of failover, the WWPN of the failing 3954

CV6 will be assumed or spoofed by the surviving failover partner, and as such

will still be in the recognized zone.

v If the switch fabric only supports hard zoning, then for failover configurations a

hard zone should be created with the host HBA port and both the port on the

primary 3954 CV6 being used for accessing the virtual library as well as the

corresponding port on the failover partner.

In simple non-failover configurations, both hard and soft zoning should be

configured with exactly one host HBA port and one TS7520 HBA port. This zoning

strategy limits the possibility for undesired configuration side effects, such as

initiators trying to log into each other. The same logic applies to TS7520 initiator

ports and physical tape target ports. Note that zones are not partitions: a given HBA

may be in many different zones.

TS7520 zoning considerations

For example, for the case of upstream (Client Host or Backup Server) zoning, if

there are two client initiators and two TS7520 Virtualization Engine targets on the

same FC fabric, and if it is desirable for all the four path combinations to be

established, it is recommended that you use four specific zones, one for each path:

v Client_Init1/VE_Tgt1





It is tempting to simply create a single zone that includes all four ports, which

appears to be have the same effect. However, this causes undesirable side effects

because of the lack of isolation among the initiators and targets. The four-zone

method is cleaner because it does not allow the two Client initiators or the two

TS7520 Virtualization Engine Target ports to see each other. This eliminates all the

potential issues such as Initiators trying to log in to each other under certain

conditions.

Follow the same method for downstream (storage) zoning. If there are two TS7520

Virtualization Engine initiators and two Storage targets on the same fabric, establish

four zones:

v VE_Init1/Storage_Tgt1




Additionally, make sure that the real tape device fibre interfaces that are attached to

the TS7520 initiators are not zoned with the client host HBAs.

As shown in the following illustrations, by default, logical adapters 4and 6(as

reported by the VE Console) are zoned to servers, and logical adapters 5 and 7 are

zoned to the physical tape library.

Figure 10 on page 78 shows a zoning example for a TS7520 Virtualization Engine

SAN configuration with both virtual and physical tape drives.

Note: In this configuration, the backup servers only have direct access to LTO 3

drive B. Any access to LTO 3 drive A is through the TS7520.


Figure 11 on page 79 shows a zoning example for a TS7520 Virtualization Engine

SAN configuration with all virtual tape drives.

Note: In this configuration, all access to the LTO 3 drives is through the TS7520.

Figure 10. TS7520 Virtualization Engine SAN configuration zoning with virtual and physical tape drives


LUN masking

After zoning has been established, you may limit the access a given host HBA has

to only those virtual drives you want to make visible to it, regardless of the access

provided by the physical connection and zone residency. The TS7520 provides a

LUN masking facility which may be used to specify which virtual device accessible

by a TS7520 port in a given zone may be seen by the attached host HBA in the

zone. This can facilitate sharing of virtual libraries, if needed, and static load

balancing. In general, virtual libraries are not shared among hosts, but the LUN

masking facility permits this to occur in a controlled fashion.

Chapter 6. IBM service installation responsibilities

The IBM installer is responsible for performing the followings tasks during the

installation of the TS7520.

v Unpack and setup the TS7520 frame.

v Connect the network cables (provided by the customer) to the network switches

(provided by the customer) in the customer configuration.

v Set IP addresses according to customer-provided network assignments.

v Enable licenses.

v Verify that the TS7520 hardware is functioning properly.

v Verify communications between TS7520 and VE Console.

v Install any hardware features that enabled advanced functions. Enablement is

performed at the VE Console.

v Initial execution of the Failover/Failback Wizard.

v Provide TS7520 Virtualization Engine frame-to-frame connections, such as the

cabling connections from the TS7520 Virtualization Engine base frame to the

TS7520 Virtualization Engine expansion frame



Chapter 7. Planning your TS7520 setup

During installation, IBM customizes the setup of your TS7520 based on information

that you provide in the customization work sheets.

Each time you install a TS7520, you must complete the customization work sheets

before the IBM service representatives can perform the installation.

The customization work sheets allow you to specify the initial setup for the

following:

v Company information

v VE Console network settings

v Remote support (includes call home and remote service settings)

v Control Switch settings

This information is gathered by IBM when you fill out the following work sheets:

v Appendix C, “Company information work sheet,” on page 95

v Appendix D, “TS7520 Virtualization Engine console network settings work sheet,”

on page 97

In addition, review Appendix B, “Setting notifications,” on page 93 for information

about SNMP trap and e-mail notification settings.

Attention: IBM service representatives cannot install the TS7520 Virtualization

Engine until you provide them with the completed customization work sheets.

TS7520 Ethernet requirements

When installing the TS7520 Virtualization Engine, the appropriate number of IP

addresses must be provided. Also, the user must provide the following hardware

and cabling resources prior to the installation of the TS7520 Virtualization Engine.

v Ethernet switches and cables for connecting the TS7520 Virtualization Engine to

the VE Console

v Fibre Channel switches and cables for connecting the TS7520 Virtualization

Engine to the hosts and tape devices or libraries.

Chapter 8. Planning data migration

Use these data migration considerations to formulate your data migration plan.

There are three levels of considerations to keep in mind when selecting the best

method for your environment. At the first level, you consider broad questions about

your environment to create a generic profile of your needs. At the second level you

compare which migration methods fit into your generic profile. The level is to review

a set of hints and other guidelines that apply to specific environments or that may

help you take advantage of a migration to optimize your environment.

The following are some key questions to use to define your generic migration

environment

v Why is the data migrating?

v How much data is migrating?

v How quickly must the migration be performed?

v What duration of service outage can be tolerated?

v Is the data migration to/from the same type storage?

v What resources are available for the migration?

After determining general answers to the considerations listed above, a better

understanding of some of the migration options along with their advantages and

disadvantages will help frame your generic profile into a subset of acceptable

migration options.

Appendix B. Setting notifications

The RSA port on the TS7520 Virtualization Engine Server is capable of sending

e-mail or SNMP alerts to the customer for 3954-CV6 hardware alerts. If you choose

to receive SNMP alerts, SNMP MIB files are available on the Base Firmware

Update disk; these files can be used to compile on your SNMP server. The system

administrator who manages the SNMP server must compile these MIB files based

on the SNMP server software being used.

The Remote Supervisor Adapter II Slimline and Remote Supervisor Adapter II

User’s Guide is shipped with the TS7520. This document contains the procedures

for configuring the RSA port for email and SNMP alerts. Instructions for compiling

the MIB files on the SNMP server are not provided in this document and will vary

depending on the SNMP server being used.

Note: Compiling these MIB files is a customer responsibility.

The following steps describe how to set up SMTP and e-mail notifications.
