PRELIMINARY DRAFT:Logical Network Configuration Chapter 2. Fibre Channel Network

Logical Network ConfigurationThe Fibre Channel (FC) ports of a IBM XIV Storage System are arranged with four ports in each interface module. This section describes the connectivity options available for the Fibre Channel network.

Note: Always check the latest version of the XIV Interoperability Matrix to determine if a specific configuration is supported.

Recommended High-availability ConfigurationThe optimal high-availability configuration is illustrated in Figure 2-1.Figure 2-1 shows only an example, as all interface modules can be used in this configuration,

The following guidelines apply to this configuration:• Each IBM XIV Storage System module is connected to two FC switches, using the

module's two ports.

• Each host is connected to two switches, using two HBAs (Host Bus Adaptors), or an HBA with two ports.

This configuration assures full connectivity under single failure of any individual component, as follows:• Upon switch failure, each host remains connected to all modules, through the

second switch.

• Should a module fail, each host remains connected to the other two modules.

• Upon a FC switch replacement or software upgrade, the hosts remain connected to the storage system.

Chapter 3. iSCSI Configuration

Physical Requirements

The IBM XIV Storage system is available in configurations:

Table 3-1 summarizes the currently available rack configurations for iSCSI ports.

Three interface modules support iSCSI, with two ports in each module.

This chapter applies to the full rack (15 module) system only.

Logical Network Configuration

Logical network configurations for iSCSI are equivalent to logical configurations suggested for FC networks. Four options are available:

• High Availability: Each module is connected through two ports to two different Ethernet switches, and each host is connected to the two switches. This provides a network architecture resilient to failure of any individual network switch or module.

• Single Switch Configuration: A single switch interconnects all modules and hosts.

• Single Port Host Solution: Each host is connected to a single switch, and a switch is connected to two modules.

• Direct connectivity to host connection: Each module is connected directly to a host.

PRELIMINARY DRAFT:Ethernet Link Aggregation Chapter 3. iSCSI Configuration

Ethernet Link AggregationIBM XIV Storage System supports the configuration of Ethernet link aggregation, where two Ethernet ports of the same module are connected to the same switch, and are considered as one logical Ethernet port (including fail-over and load balancing).

iSCSI Network Configuration

IP Configuration

Configuration of the IBM XIV Storage System iSCSI connection is highly dependent on the customer's network. The two Ethernet switches used for redundancy may be configured as either different IP subnets or as part of the same subnet.IBM XIV Storage System iSCSI configuration should match the user's network. The user should provide the required configuration information for each Ethernet port as follows:• The user must decide whether to configure the two ports of each module as either

one logical Ethernet port (link aggregation) or two independent Ethernet ports. This decision affects both how the system and switch are configured.

• IP address • Net mask • MTU (optional)• Default gateway (optional)MTU configuration is required if the user's network supports an MTU which is larger then the standard one. The largest possible MTU should be specified (it is advisable to use up to 9,000 bytes, if supported by the switches and routers).If the iSCSI hosts reside on a different subnet than IBM XIV Storage System, a default IP gateway per port should be specified.

Note: As IBM XIV Storage System always acts as a TCP server for iSCSI connections, packets are always routed through the Ethernet port from which the iSCSI connection was initiated. The default gateways are required only if the hosts do not reside on the same layer-2 subnet as the IBM XIV Storage System.

IP Network Configuration

IP network configuration should be ready to ensure connectivity between the IBM XIV Storage System and the host, including the following:• If required, Ethernet switches that connect to two ports on the same module

should configure their ports as a link aggregation group (with a parallel configuration on the IBM XIV Storage System module).

• Ethernet VLANs (if required) should be configured correctly to enable access between hosts and the IBM XIV Storage System.

• IP Routers (if present) should be configured correctly to enable access between hosts and the IBM XIV Storage System.

Chapter 4. Mixed iSCSI and FC Host Access

IBM XIV Storage System supports mixed concurrent access from the same host to the same volumes through FC and iSCSI. When building such a topology, you must plan carefully to properly ensure redundancy and load balancing.

Please contact IBM XIV support if you want to configure both FC and iSCSI access from the same host.

Notes: 1. Not all hosts support multi-path configuration between the protocols.

2. In a partial rack (6 module) configuration, not all patch panel interface ports are active.:

- Fiber Channel connections are active only for modules 4 and 5.- No iSCSI connections are active.

Chapter 5. Remote Mirroring Network Configuration

Please contact IBM XIV support for assistance for planning remote mirroring connectivity to assure maximum resilience to hardware and connection failures.


PRELIMINARY: 1

Chapter 6. Management Connectivity

Physical Management PortsIBM XIV Storage System is managed through three IPs over Ethernet interfaces, in order to be resilient to two hardware failures. Thus, the user should have three Ethernet ports available for management. If you require management to be resilient to a single network failure, it is advised that you connect these ports to two different switches.Make sure that the networking equipment providing the management communication is UPS protected.

Management IP ConfigurationFor each of the three management ports, the following configuration information should be provided to XIV upon installation:• IP address of the port

• Net mask

• Default IP gateway

The following system-level IP information should be provided (not port-specific):• IP address of the primary and secondary DNS servers

• IP address or DNS names of the SNMP manager, if required

• IP addresses or DNS names of the SMTP servers

ProtocolsIBM XIV Storage System is managed through dedicated management ports, running TCP/IP over Ethernet. Management is carried out through the following protocols (please take this into account when configuring firewalls, and other security protocols):• Proprietary IBM XIV protocols are used to manage IBM XIV Storage System from

the GUI and CLI. This management communication is performed over TCP port 7778, where the GUI/CLI, as the client, always initiates the connection and the IBM XIV Storage System performs as the server.

• IBM XIV Storage System responds to SNMP management packets.

• IBM XIV Storage System initiates SNMP packets when sending traps to SNMP managers.

• IBM XIV Storage System initiates SMTP traffic when sending e-mails (for either event notification via e-mail, or for e-mail-to-SMS gateways).

Chapter 7. Remote Access and Call Home

Call Home ConnectionIBM XIV Call Home connects your system directly to the IBM trouble?ticketing system, enabling both failure and proactive, pre-failure notifications to be sent automatically to IBM. When you enable Call Home support, the 2810 sends (via email) an electronic call home record to IBM support when there is a problem with the machine. When a problem requiring service is received by IBM, a service representative is dispatched with the necessary replacement parts. The Call Home alerts are sent by email (SMTP), using the customer’s SMTP server. So in order to use this capability, the 2810 must be configured to use an external SMTP server, and be allowed to send messages to IBM using this server. The configuration of the 2810 for Call Home is normally done when the 2810 is first installed.

Remote Support ConnectionsIBM recognizes that there can be instances in which the 2810 has detected problems that require IBM service personnel to perform real-time problem analysis and isolation. To address this possibility, IBM has designed a secure network interface that allows authorized IBM personnel to access the 2810 storage servers over a public network or over a telephone modem connection. Remote-access support can help to greatly reduce service costs and shorten repair times, which in turn lessens the impact of any failures on your business. Remote access is supported by either the modem feature (feature code 9101), or by using a dedicated Ethernet connection to one or both of the VPN ports.

Remote Access by ModemTo use the modem for remote access, a telephone line must be connected to the modem, and the telephone number of the line provided to IBM. The 2810 does not make a outgoing calls using the modem, so the telephone line need not support dialing out.

Remote Access by Broadband ConnectionTo use a broadband connection for remote access, the network connection must be made to the VPN port connections on the patch panel. The VPN ports should be connected through your organization's firewall so that IBM XIV personnel can access the IBM XIV Storage System, if required. Access can be limited to be from IBM XIV's IP address space only. It is also possible to configure a VPN between IBM XIV's offices and the organizational firewall, enabling access to this port only through the defined VPN. The IBM XIV 2810 Storage System only accepts connections on server port 22, and also uses port 7778. The 2810 never uses these ports for outgoing IP traffic. This connection is made by the two "VPN" ports on the patch panel. The following configuration regarding the remote access port must also be provided:• IP address of the remote access ("VPN") ports.

• Network mask

• Default gateway

• External IP address (The IP address to which IBM support will connect.)

Chapter 8. Laptop Port

The IBM XIV Storage System has two Ethernet laptop ports. These ports should be used only by IBM service personnel. A single laptop, or other computer, can be connected to these ports, and once connected the system will serve as a DHCP server and will automatically configure the laptop.Attention: These ports should be used for direct laptop connections only, and must not be connected to the network. A DHCP server is implemented over this port and a connection to the network might cause an assignment of the wrong IP addresses to the user’s hosts.
