Pci And Pci-X Slots And Adapters - IBM p5 590 System Handbook

Use the following guidelines when configuring media devices or NIM server:
FC 5795 provides a frame-based media bay solution for the p5-590 and
p5-595 servers.
External media device models 7212-102, 7210-025, or 7210-030 are devices
for reading CD media.
External media devices attach to a PCI SCSI adapter in one of the system I/O
drawers.
A NIM server must attach to a PCI LAN adapter in one of the system I/O
drawers (an Ethernet adapter is recommended).
A minimum of two internal SCSI hard disks are required per p5-590 or p5-595
server. We recommend that these disks be used as mirrored boot devices and
that the disks are separated with as much hardware redundancy as possible,
including RIO loops, SCSI backplanes, I/O drawers, and GX adapters. This
configuration provides service personnel with access to the maximum amount of
diagnostic information if the system encounters errors in the boot sequence and
the AIX error logs or system diagnostic services are required.
Boot support is also available from local SCSI, SSA, and Fibre Channel
adapters, or from networks using Ethernet or Token-Ring adapters
For AIX 5L Version 5.2 and 5.3 logical partitions, consideration should be
given to the placement of the AIX 5L rootvg volume group in the first I/O
drawer. This allows AIX 5L to boot any time other I/O drawers are found offline
during boot.
If the boot source other than internal disk is configured, the supporting
adapter should also be in the first I/O drawer
The p5-590 and p5-595 servers incorporate an Early Power Off Warning (EPOW)
capability that assists in performing an orderly system shutdown in the event of a
sudden power loss. IBM recommends use of the Integrated Battery Backup
features or an uninterruptedly power system (UPS) to help ensure against loss of
data due to power failures.

5.2.8 PCI and PCI-X slots and adapters

The purpose of this section is to provide configuration guidelines for PCI and
PCI-X adapters.
System maximum limits for adapters and devices may not provide optimal
system performance; these limits are given for connectivity and function
information.
