– 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

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

Storage attach terminology

Direct attach – switch or fabric device is not required between the adapter and the storage device

Native attach – switch or fabric device is required between the adapter and the storage device

Virtual SCSI – A virtual I/O server (VIOS or IBM i) provides a virtual SCSI adapter to a client operating system (IBM i, AIX, or Linux)

N_Port ID Virtualization (NPIV) – aka virtual fibre channel – A virtual I/O server (VIOS) provides a virtual fibre channel adapter to the client operating system (IBM i, AIX, or Linux)

PowerHA SystemMirror

IBM Power Systems integrated end to end solution for HA and/or DR • Focus: 24 x 7 application availability • Planned or unplanned outages• Deeply integrated extension of IBM i (implemented in LIC and the OS)

Clustering technology • Provides the applications with a complete resiliency infrastructure• Monitors and manages primary and secondary resources for HA and DR operations

Storage based data resiliency• Data resiliency is an extension of the host system storage management architecture• Storage volumes are either switchable or mirrored between nodes in the cluster• Hardware based replication services for Multi-Site Operations

• Host Based Replication (Geographic mirroring for IBM i or GLVM for AIX)• Storage Base Replication (Metro Mirror or Global Mirror)

Overall solution characteristics • Automation to minimize IT operations staff involvement• Data between primary and secondary nodes always in sync and always ready for a

failover event

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.


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

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 http://www.ibm.com/systems/p/hardware/system_perf.html .

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 1.4.2 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.

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: www.ibm.com/systems/i/solutions/perfmgmt/resource.html
