Note: External I/O drawers 7311-D11, 7311-D20, and 7314-G30 are not supported on the
Power 595 servers.
The Power 595 has the following minimum and maximum configurable I/O device allocation
requirements:
The 595 utilizes 4U-tall remote I/O drawers for directly attached PCI or PCI-X adapters
and SCSI disk capabilities. Each I/O drawer is divided into two separate halves. Each half
contains 10 blind-swap PCI-X slots for a total of 20 PCI slots and up to 16 hot-swap disk
bays per drawer.
When an AIX operating system is specified as the primary operating system, a minimum
of one I/O drawer (#5791) per system is required in the 5U location within the system rack.
When an IBM i operating system is specified as the primary operating system, a minimum
of one PCI-X Expansion Drawer (#5790) per system is required in a 19-inch expansion
rack. A RIO-2 Remote I/O Loop Adapter (#6438) is required to communicate with the 595
CEC RIO-G Adapter (#1814).
When the 12X I/O drawers (#5797. #5798) is available, the above minimum requirement
will be replaced by one feature #5797 or #5798 per system in the 5U location within the
system rack. All I/O drawer feature #5791, #5797, or #5798 contain 20 PCI-X slots and 16
disk bays.
Note: The 12X I/O drawer (#5798) attaches only to the central electronics complex
using 12X cables. The 12X I/O drawer (#5797) comes with a repeater card installed.
The repeater card is designed to strengthen signal strength over the longer cables used
with the Power Expansion Rack (#6954 or #5792) and nonpowered, bolt-on Expansion
Rack (#6983 or #8691). Features #5797 and #5798 will not be supported in p5-595
migrated Expansion Rack.
7040-61D I/O drawers are supported with the 9119-FHA.
A maximum of 12-feature #5791 (or #5807), 5794 (specified as #5808), or 30-feature
#5797 I/O drawers can be connected to a 595 server. The total quantity of features
(#5791+#5797+#5798+#5807+#5808) must be less than or equal to 30.
One single-wide, blind-swap cassette (equivalent to those in #4599) is provided in each
PCI or PCI-X slot of the I/O drawer. Cassettes not containing an adapter will be shipped
dummy
with a
card installed to help ensure proper environmental characteristics for the
drawer. If additional single-wide, blind-swap cassettes are needed, feature #4599 should
be ordered.
All 10 PCI-X slots on each I/O drawer planar are capable of supporting either 64-bit or
32-bit PCI or PCI-X adapters. Each I/O drawer planar provides 10 PCI-X slots capable of
supporting 3.3-V signaling PCI or PCI-X adapters operating at speeds up to 133 MHz.
Each I/O drawer planar incorporates two integrated Ultra3 SCSI adapters for direct
attachment of the two 4-pack hot-swap backplanes in that half of the drawer. These
adapters do not support external SCSI device attachments. Each half of the I/O drawer is
powered separately.
For IBM i applications, if additional external communication and storage devices are
required, a 19-inch, 42U high non-powered Expansion Rack can be ordered as feature
#0553. Feature #0553 (IBM i) is equivalent to the 7014-T42 rack, which is supported for
use with a 9119-FHA server.
