IBM 7133 Serial Disk Subsystem (SSA)

The p5-570 system supports the Advanced Serial RAID adapter (FC 6230), to attach the IBM 7133 Serial Disk Subsystem Model D40, if migrated from a pSeries system.

The IBM 7133 Serial Disk Subsystem Model D40 provides a 4U highly available storage subsystem for pSeries servers and is a good solution for providing disks for booting additional LPARs. Disks are available from 18.2 GB to 72.8 GB at the time this publication was written. SSA disk subsystems are connected to the server in loops. Each 7133 disk subsystem provides a maximum of four loops with a maximum of four disks each. Therefore, up to four additional LPARs could be provided with disks with dedicated loops for booting by using one Advanced Serial RAID Plus adapter (FC 6230) for each LPAR. Disk space for booting could be provided in JBOD (Just a Bunch Of Disks) or RAID mode.

Notes: FC 6230 serial RAID adapters provide boot support from a RAID-configured disk with firmware level 7000 and above.

Fastwrite cache must not be enabled on the boot resource SSA adapter.

IBM TotalStorage FAStT Storage servers

The IBM TotalStorage FAStT Storage server family consists of five models: 100, 200, 600, 700, and 900. As this publication was written Model 100 was the smallest model, scaling to 14 TB. Model 900 is the largest, and it scales to 32 TB. Model 600 provides up to 16 bootable partitions, which are attached with the Gigabit Fibre Channel adapter (FC 6239 or FC 5716). Model 700 provides up to 64 bootable partitions. In most cases, both the FAStT storage server and the p5-570 or the 7311 I/O drawers are connected to a Storage Area Network (SAN). If space is needed only for the rootvg, the FAStT Model 100 or 200 is a good solution.

Note: To boot the p5-570 system, one logical partition, or any other pSeries server from a SAN using FC 6239, the adapter microcode 3.22A1 or later is required. Boot support is provided from direct-attached FastT as well as from SAN attached FastT.

IBM TotalStorage Enterprise Storage Server®

The IBM TotalStorage Enterprise Storage Server (ESS) is the high-end premier storage solution for use in Storage Area Network. The 2105 Model 800 provides from 582 GB to

55.9TB of usable disk capacity. An ESS system could also be used to provide disk space for booting LPARs or partitions using Micro-Partitioning technology. An ESS is usually connected to a Storage Area Network (SAN) to which the p5-570 is also connected by using Gigabit Fibre Channel adapters (FC 6239 or FC 5716).
