The Power 595 server must have access to a device capable of reading CD/DVD media or to
a NIM server. The recommended devices for reading CD/DVD media is the Power 595 media
drawer (#5720), or and external DVD device (7214-1U2, or 7212-103). Ensure there is a SAS
adapter available for the connection.
If an AIX or Linux for Power operating system is specified as the primary operating system, a
NIM server can be used. The recommended NIM server connection is a PCI based Ethernet
LAN adapter plugged in one of the system I/O drawers.
If an AIX or Linux for Power operating system is specified as the primary operating system, a
minimum of two internal SCSI hard disks is required per 595 server. It is recommended that
these disks be used as mirrored boot devices. These disks should be mounted in the first I/O
drawer whenever possible. This configuration provides service personnel the maximum
amount of diagnostic information if the system encounters any errors during in the boot
sequence. Boot support is also available from local SCSI and Fibre Channel adapters, or
from networks via Ethernet or token-ring adapters.
Placement of the operating systems disks in the first I/O drawer allows the operating system
to boot even if 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.
Table 1-14 lists the available Power 595 media drawer features.

1.3.4 I/O Drawers attachment (attaching using RIO-2 or 12x I/O loop adapters)
Existing System i and System p model configurations have a set of I/O enclosures that have
been supported on RIO-2 (HSL-2) loops for a number of years.
Most continue to be supported on POWER6 models. This section highlights the newer I/O
enclosures that are supported by the POWER6 models that are actively marketed on new
orders. See 2.8, “Internal I/O subsystem” on page 82 for additional information about
supported I/O hardware.
System I/O drawers are always connected using RIO-2 loops or 12X HCA loops to the GX
I/O hub adapters located on the front of the processor books. Drawer connections are
always made in loops to help protect against a single point-of-failure resulting from an
open, missing, or disconnected cable.
