Rev. 3.11 Lab 8 17

14. Run the configdownload command to download the merged configuration(Merge_FabricAB_CFG) to the switch.

NoteThe spare switch will now have both configurations for FabricB andthe merged Fabric. The configdownload command will make theMerge_FabricAB_CFG the effective configuration.

15. Run the cfgdisableMerge_FabricAB_CFG command to disable theeffective configuration.

16. With the switchenable command, enable the switch.

17. When you enable the spare switch, the Merge_FabricAB_CFG will become part of FabricB but will not be the effective configuration.

18. Run the cfgenable Merge_FabricAB_CFG command to make the newmerged configuration the effective configuration.

19. With the cfgshow command, verify that the new configuration is in effect.

20. Plug a fiber cable between FabricA and FabricB, and observe what happens.

Case 2NEWCO SoftDev

HP has been doing business with the NEWCO Corporation, including the softwaredevelopment division for quite some time. This is a small division, whencompared to the others, and they have offices in the same general area as other divisions. A HP Sales person, and SE have been out to the site, and have compileda description of their current setup, needs, and future plans.

The HP sales team tells us that NEWCO-SoftDev has bought HP x86 basedservers from us in the past and have been happy with them. They currently have

NetWare servers used for file and print serving for their software developers. TheCIO and his staff are finding it increasing more difficult to find talent to maintaintheir NetWare environment, and for other reasons, some political, have started a

process of converting to Windows NT.

They currently have three NT servers that are running on HP Proliants. One is a

primary domain controller (PDC) and the other two are configured as backupdomain controllers (BDC). They are looking to consolidate the remaining Novell

NetWare servers into 1 or 2 NT servers where possible. They hope to re-deploy theexisting NetWare server hardware as NT servers. The current servers runWindows NT version 4.0 but it is anticipated that Windows 2000 Advanced Server will be used in the near future. They anticipate that their newer applications willrequire more and more data to be stored and served, particularly for the high

bandwidth applications that they are developing.

Legacy support includes a Sun system and a Tru64 system used for someapplications needed by the developers that require Unix. The Tru64 system is anAlpha Server currently connected to an HP StorageWorks RAID Array 8000(RA8000) using only a fraction of its capacity, and the Sun Server is directconnected to another storage system. They can save paying a service contract onthe Sun storage if it could be moved to the RA8000 storage system. Developmentneeds to be able to test new builds of software against production data withoutimpact to users. Data stored on this RA8000 needs to be highly available.

Currently, all NT and NetWare servers have a locally attached DAT drive. Eachnight, server backups take about 7 hours. This is not an issue since all of the

backups can run concurrently. However, this is an issue for administrative reasons,as the backup operators must coordinate multiple backups on different systems,some in other locations, at the same times. The operators frequently have to

schedule a restore to bring back files accidentally deleted by the developers.Sometimes a developer has to wait till the following day for a deleted file to berestored before they can continue work.


85/169


2 Rev. 3.11

This group holds a small staff of developers. The amount of storage they needchanges from project to project. Currently moving disks between the servers is theanswer. They are also backing up images of the production data to test and runreports against offline. While there is adequate network and server performance,restore time of production data is unacceptably long. if the tests are unsuccessful.

There are also frequent requests for more storage space, and new network shareshave to be created for the developers. The day operations staff is overburdenedwith managing multiple servers, and they are desperate for a better solution.

A sister division at NEWCO has inquired about the possibility of having arecovery site housed within the SoftDev location. The CIO is not opposed to this,

but wants to know the requirements before he makes that decision. This is typicalof the CIO. He always wants to know how much things will cost, and always asksif there is a more economical way to achieve the same or nearly the same results.His division is seen as a cost center by the other divisions, and corporateheadquarters, and he frequently has to ask for funding from them. The corporateheadquarters will also want to make sure that any new technology purchased will

work across divisions, and integrate into a corporate wide infrastructure.

Purchasing decision driversUse as much of the existing equipment as possible.

Centralized backups.

An automated way of creating multiple copies of production data quickly, toaddress testing by developers.

Maintain support for the Sun and Tru64 system.

Assist in providing a recovery site for sister division.

Connect the Tru64 and the Sun system to the same RA8000.

Ensure high availability of the data on the SUN and Tru64 systems.

Provide for bandwidth growth on NT systems. Network and SAN.

Virtual storage that can be easily moved from server to server.

Ability for users to recover files deleted same day.

Ability to provide reporting of storage utilization to CIO.

87/169


2 Rev. 3.11

Because of the work done in the Services group, there is a need to create, use, andthen delete storage volumes on an ongoing basis. Currently, when one of theteams needs additional disk space to test a new version of an application, they take

physical disks from other servers, and install them in the server needing the space.This is a very common and time consuming process for the IT staff which have to

wait for the technical support folks to come in and execute the procedure.Another issue has to do with rollback that is required if a second test scenario is to

be performed. Currently, a backup is needed after each version is installed anddocumented. This backup is temporary and used only if they have to return to a

particular configuration. As before, this is very time consuming process butnecessary. The support staff would really benefit from having a flexible, easy touse virtual disk solution with the ability to capture point-in-time copies. As asupport group, having extremely high storage bandwidth is not a major concern.

Purchasing decision drivers

Consolidation of storage.Increased backup window.

Highly available, virtual disk solution with charge back capability.

Easy creation of disks for developers.

Point-in-time copy for developers.

Assisting with disaster tolerant/disaster recovery for Newco-HQ

Increased bandwidth for NT server supporting the virtual disks.

Heterogeneous SAN ImplementationLab 11

ObjectivesThis lab is designed to be challenging and does not include detailed steps. You willapply the concepts that were covered in the various sections throughout the course.There are a number of tasks that are listed as a requirement that need to beimplemented and tested.

Your instructor will verify that you have completed the tasks successfully.

This lab will cover:

The implementation of a Heterogeneous operating system SAN.

Storage consolidation and selective storage presentation.

Configurations with no-single-point-of-failure (NSPOF) between the host(s)and the associated storage systems.

EBS in a SAN based on Veritas Backup Exec.

BC Upgradeon NT to provide non-disruptive backups.

Lab 11 2 Rev. 3.11

Tasks1. Use the supplied worksheets to design and build a fully meshed resilient

fabric with 4 switches that comply with the fabric design rules of: 1 Hop under normal operation. 2 Hops under an error condition.

2. Within the SAN, install and configure the following: Two NT servers to access one HP StorageWorks Modular Array 8000

(MA8000) (or equivalent) storage system with NSPOF. Each server should have exclusive access to its storage within the

MA8000. Each server should have access to at least 2 LUNs. One server is going to run a database and will perform a lot of online

transaction processing. The second server will be used to download seismic data that consists of

very large files that average 200MB. The storage system configuration should be optimized to these

environments. The storage systems will be located on different switches than the

servers. The two switches act as distance extenders to ensure that the server site

and storage sites can be connected.

3. Install and configure SWCC to manage the storage systems.4. Configure a SUN host in the SAN with its own storage by adding another

MA8000 (or equivalent) and isolate the SUN host and its associated storagefrom the NT servers and NT storage.

5. Add EBS to the SAN and configure backup for all the NT servers withVeritas Backup Exec.

6. Configure HP StorageWorks Business Copy Upgrade (BC Upgrade) for the NT servers. Designate one server as the client and the other as the server.

7. Setup management within the SAN using the HP OpenView Storage

Management Appliance to manage the switches and the storage controllers.

Rev. 3.11 Appendix A 1

Appendix A Iometer

This section briefly explains the use of Iometer. See your instructor for additional help. Iometer can be downloaded from the Intel Developers' WebSite at the following URL:http://sourceforge.net/projects/iometer/

In order to monitor performance in the SAN you must create I/O between the hostsand their respective storage systems. These steps will discuss how to setup Iometer for this purpose but other tools maybe used.

Iometer is both a workload generator and measurement tool. It can be used toemulate disk I/O or to generate synthetic workloads.

Configuration steps for Iometer:

a. Copy the software to the host.

b. Execute IOMETER.EXE to start the application.
