Agenda

• Where to start with IBM i on blade

• Hardware overview:– Power blade servers technical overview– New expansion adapters– BladeCenter S components and I/O connections– BladeCenter H components and I/O connections– Switch module portfolio– Expansion adapter portfolio for IBM i– Feature codes and ordering

• Virtualization overview– VIOS-based virtualization overview– I/O options for BladeCenter H and BladeCenter S– Configuring storage for IBM i on blade– Configuring storage with the SAS RAID Controller Module– Virtual tape– Multiple Virtual SCSI adapters– Active Memory Sharing on blade

Storage and Tape Support 2Q 2009

• Storage support– BladeCenter H and JS12/JS22/JS23/JS43:

• SAS – DS3200 • Fibre Channel – DS3400, DS4700, DS4800, DS8100, DS8300, SVC

– Multiple storage subsystems supported with SVC

• IBM is investigating DS5100, DS5300 and XIV support for Power blades

– BladeCenter S and JS12/JS22/JS23/JS43:• SAS – BCS drives with NSSM and RSSM; DS3200 only with NSSM

• Tape support– BladeCenter H and BladeCenter S:

• TS2240 LTO-4 SAS – supported for virtual tape and for VIOS backups• TS2230 LTO-3 SAS – not supported for virtual tape, only for VIOS backups

– IBM is investigating Fibre Channel tape library support for 4Q 2009


Configuring Storage for IBM i on Blade

• Step 1: Perform sizing– Use Disk Magic, where applicable– Use the PCRM, Ch. 14.5 – http://www.ibm.com/systems/i/advantages/perfmgmt/resource.html

– Number of physical drives is still most important– VIOS itself does not add significant disk I/O overhead– For production workloads, keep each i partition on a separate RAID array

• Step 2: Use appropriate storage UI and Redbook for your environment to create LUNs for IBM i and attach to VIOS (or use TPC or SSPC where applicable)

Storage Configuration Manager for NSSM and

RSSM

DS Storage Manager for DS3200, DS3400, DS4700,

DS4800

DS8000 Storage Manager for DS8100 and DS8300

SVC Console for SVC


Configuring Storage for IBM i on Blade, Cont.

• Step 3: Assign LUNs or physical drives in BCS to IBM i– ‘cfgdev’ in VIOS CLI necessary to detect new physical volumes if VIOS is running– Virtualize whole LUNs/drives (“physical volumes”) to IBM i– Do not use storage pools in VIOS


Configuring Storage with the RSSM

• Step 1: download SCM – http://www-947.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5078617&brandind=5000016 • Step 2: install SCM and add RSSM in Bay 3 (get IP address from AMM)• Step 3: use SCM to create RAID arrays (storage pools) and volumes,

and to assign volumes to blades

• See Readme for details


IBM i Support for Virtual Tape

• Virtual tape support enables IBM i partitions to directly backup to PowerVM VIOS attached tape drive saving hardware costs and management time

• Simplifies backup and restore processing with BladeCenter implementations

– IBM i 6.1 partitions on BladeCenter JS12, JS22, JS23, JS43– Supports IBM i save/restore commands & BRMS– Supports BladeCenter S and H implementations

• Simplifies migration to blades from tower/rack servers– LTO-4 drive can read backup tapes from LTO-2, 3, 4 drives

• Supports IBM Systems Storage SAS LTO-4 Drive– TS2240 SAS ONLY for BladeCenter– IBM is investigating Fibre Channel tape library support for 4Q 2009

• Requirements– VIOS 2.1.1, eFW 3.4.2, IBM i 6.1 PTFs

Assigning Virtual Tape to IBM i

• No action required in IBM i to make tape drive available– If QAUTOCFG is on (default)


Migrating IBM i to Blade

• Virtual tape makes migration to blade similar to migration to tower/rack server:– On existing system, go save option 21 on LTO-2, LTO-3 or LTO-4 media

– On blade, use virtual tape to perform D-mode IPL and complete restore

– Existing system does not have to be at IBM i 6.1• Previous-to-current migration also possible

• IBM i partition saved on blade can be restored on tower/rack server– IBM i can save to LTO-3 and LTO-4 media on blade

• For existing servers that do not have access to LTO tape drive, there are two options:– Save on different media, convert to LTO as a service, restore from LTO

– Use Migration Assistant method


Multiple Virtual SCSI Adapters for IBM i

• Since VIOS 2.1 in November 2008, IBM i is no longer limited to 1 VSCSI connection to VIOS and 16 disk + 16 optical devices

• What IVM will do:– Create 1 VSCSI server adapter in VIOS for each IBM i partition created

– Create 1 VSCSI client adapter in IBM i and correctly map to Server adapter

– Map any disk and optical devices you assign to IBM i to the first VSCSI server adapter in VIOS

– Create a new VSCSI server-client adapter pair only when you assign a tape device to IBM i

– Create another VSCSI server-client adapter pair when you assign another tape device

• What IVM will not do:– Create a new VSCSI server-client adapter pair if you assign more than 16 disk

devices to IBM i


Multiple Virtual SCSI Adapters for IBM i, Cont.

• Scenario I: you have <=16 disk devices and you want to add virtual tape– Action required in VIOS:

• In IVM, click on tape drive, assign to IBM i partition– Separate VSCSI server-client adapter pair created automatically

• Scenario II: you have 16 disk devices and you want to add more disk and virtual tape– Actions required in VIOS:

• In VIOS CLI, create new VSCSI client adapter in IBM i– VSCSI server adapter in VIOS created automatically

• In VIOS CLI, map new disk devices to new VSCSI server adapter using ‘mkvdev’• In IVM, click on tape drive, assign to IBM i partition

PowerVM Active Memory Sharing• PowerVM Active Memory Sharing is an advanced memory

virtualization technology which intelligently flows memory from one partition to another for increased utilization and flexibility of memory usage

• Memory virtualization enhancement for Power Systems– Partitions share a pool of memory – Memory dynamically allocated based on partition’s workload demands

• Extends Power Systems Virtualization Leadership– Capabilities not provided by Sun and HP virtualization offerings

• Designed for partitions with variable memory requirements

– Workloads that peak at different times across the partitions– Active/inactive environments– Test and Development environments– Low average memory requirements

• Available with PowerVM Enterprise Edition – Supports AIX 6.1, i 6.1, and SUSE Linux Enterprise Server 11

– Partitions must use VIOS and shared processors

– POWER6 processor-based systems

Notes on performance estimatesrPerf for AIX

rPerf (Relative Performance) is an estimate of commercial processing performance relative to other IBM UNIX systems. It is derived from an IBM analytical model which uses characteristics from IBM internal workloads, TPC and SPEC benchmarks. The rPerf model is not intended to represent any specific public benchmark results and should not be reasonably used in that way. The model simulates some of the system operations such as CPU, cache and memory. However, the model does not simulate disk or network I/O operations.

• rPerf estimates are calculated based on systems with the latest levels of AIX and other pertinent software at the time of system announcement. Actual performance will vary based on application and configuration specifics. The IBM eServer pSeries 640 is the baseline reference system and has a value of 1.0. Although rPerf may be used to approximate relative IBM UNIX commercial processing performance, actual system performance may vary and is dependent upon many factors including system hardware configuration and software design and configuration. Note that the rPerf methodology used for the POWER6 systems is identical to that used for the POWER5 systems. Variations in incremental system performance may be observed in commercial workloads due to changes in the underlying system architecture.

All performance estimates are provided "AS IS" and no warranties or guarantees are expressed or implied by IBM. Buyers should consult other sources of information, including system benchmarks, and application sizing guides to evaluate the performance of a system they are considering buying. For additional information about rPerf, contact your local IBM office or IBM authorized reseller.

CPW for IBM i

Commercial Processing Workload (CPW) is a relative measure of performance of processors running the IBM i operating system. Performance in customer environments may vary. The value is based on maximum configurations. More performance information is available in the Performance Capabilities Reference at: www.ibm.com/systems/i/solutions/perfmgmt/resource.html
