Refers to the processor enclosures for POWER5/5+, POWER6/6+, and POWER7/7+ systems. 520, 550, 710, 720, 730, 740, and 750 systems have a single enclosure 560, 570, 770, and 780 systems have 1 or more enclosures. DAS Direct Attach Storage aka Internal Storage Direct attach for SAN storage, attach directly to fibre channel adapter without a switch FC Fibre channel HBA host bus adapter HSL High Speed Link POWER4 thru POWER6 I/O bus interconnect, same as RIO but called HSL when used on System i IOA Input/Output Adapter IOP Input/Output Processor LIC Licensed Internal Code, part of IBM i operating environment MPIO Multi-Path I/O Native attach no need to virtualize adapters or LUNs via VIOS 3 NPIV N_Port ID Virtualization, aka virtual fibre channel PCIe PCI Express latest and fastest enhanced PCI card and slot PCI-x PCI extended enhanced PCI card and slot RIO Remote I/O POWER4 thru POWER6 I/O bus interconnect, same as HSL but called RIO when used on System p SAN Storage Area Network SAS Serial Attached SCSI SCSI Small Computer System Interface SFF Small Form Factor 2.5 HDDs or SSDs SmartIOA an IOA which doesn t require an IOP, reducing card slot usage and cost SSD Solid State Drive VFC Virtual Fibre Channel, aka NPIV VIOC virtual I/O Client VIOS Virtual I/O Server VSCSI Virtual SCSI 12X IBM s implementation of InfiniBand bus interconnect for Power servers

43 General guidelines for external storage Old guideline: DS8000 is the only option Today s reality: A wide choice of storage solutions is available Old guideline: Define 2 LUNs/DDM for best throughput Today s reality: Disk Magic can model workload to show proper quantity and size of LUNs for most IBM Storage Subsystems Old guideline: 2 4 IBM i HBAs (fibre ports) to 1 storage HA Today s reality: New Smart IOAs (IOP-less) may map 1:1 Old guideline: Create 1 DS8K extent pool per rank Today s reality: Storage Pool Striping with multi-rank extent pools for each LPAR may deliver a good balance of performance and reliability. In other words, each LPAR has 2 or more DS8000 extent pools. With Storwize, each LPAR has one (1) or more disk pools. 43

44 LUN Size Hints & Tips DS8000 specific: LUNs must be defined in specific sizes to provide 520-byte sector support for IBM i PowerHA for IBM i + NPIV or native attach requires 520-byte sector formatted LUNs Other considerations If there are insufficient LUNs or paths to the LUNs, wait time typically increases. The quantity of LUNs and paths drive the requirement for FC adapters on the IBM i Maximum 32 LUNs per IOP required adapter Maximum 64 LUNs per IOP-less adapter port or NPIV port Minimum LUN size is currently 17.5 GBs (this will change with the next release of the operating system) Maximum LUN size is 2TBs minus 512 bytes A minimum of 6 LUNs is required in any ASP where you care about performance Basic guidance says 12 LUNs per VSCSI adapter. Absolute maximum is 16. Use the IBM tool Capacity Magic to verify capacity and space utilization plans. Use the IBM tool Disk Magic to model the size and number of LUNs required 44

50 Notes on benchmarks and values The IBM benchmarks results shown herein were derived using particular, well configured, development-level and generally-available computer systems. Buyers should consult other sources of information to evaluate the performance of systems they are considering buying and should consider conducting application oriented testing. For additional information about the benchmarks, values and systems tested, contact your local IBM office or IBM authorized reseller or access the Web site of the benchmark consortium or benchmark vendor. IBM benchmark results can be found in the IBM Power Systems Performance Report at All performance measurements were made with AIX or AIX 5L operating systems unless otherwise indicated to have used Linux. For new and upgraded systems, AIX Version 4.3, AIX 5L or AIX 6 were used. All other systems used previous versions of AIX. The SPEC CPU2006, SPEC2000, LINPACK, and Technical Computing benchmarks were compiled using IBM's high performance C, C++, and FORTRAN compilers for AIX 5L and Linux. For new and upgraded systems, the latest versions of these compilers were used: XL C Enterprise Edition V7.0 for AIX, XL C/C++ Enterprise Edition V7.0 for AIX, XL FORTRAN Enterprise Edition V9.1 for AIX, XL C/C++ Advanced Edition V7.0 for Linux, and XL FORTRAN Advanced Edition V9.1 for Linux. The SPEC CPU95 (retired in 2000) tests used preprocessors, KAP 3.2 for FORTRAN and KAP/C from Kuck & Associates and VAST-2 v4.01x8 from Pacific-Sierra Research. The preprocessors were purchased separately from these vendors. Other software packages like IBM ESSL for AIX, MASS for AIX and Kazushige Goto s BLAS Library for Linux were also used in some benchmarks. For a definition/explanation of each benchmark and the full list of detailed results, visit the Web site of the benchmark consortium or benchmark vendor.

52 Notes on performance estimates rperf 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: Revised April 2,
