1.1 Model overview and attributes
The Power 595 server (9119-FHA) offers an expandable, high-end enterprise solution for
managing the computing requirements to enable your business to become an On Demand
Business. The Power 595 is an 8- to 64-core SMP system packaged in a 20U (EIA-unit) tall
central electronics complex (CEC) cage. The CEC is 50 inches tall, and housed in a 24-inch
wide rack. Up to 4 TB of memory are supported on the Power 595 server.
The Power 595 (9119-FHA) server consists of the following major components:
A 42U-tall, 24-inch system rack that houses the CEC, Bulk Power Assemblies (BPA) that
are located at the top of the rack, and I/O drawers that are located at the bottom of the
rack. A redundant power subsystem is standard. Battery backup is an optional feature.
CEC features include:
– A 20U-tall CEC housing that features the system backplane cooling fans, system
electronic components, and mounting slots for up to eight processor books.
– One to eight POWER6 processor books. Each processor book contains eight,
dual-threaded SMP cores that are packaged on four multi-chip modules (MCMs). Each
MCM contains one dual-core POWER6 processor supported by 4 MB of on-chip L2
cache (per core) and 32 MB of shared L3 cache. Each processor book also provides:
• Thirty-two DDR2 memory DIMM slots
• Support for up to four GX based I/O hub adapter cards (RIO-2 or 12x) for
• Two Node Controller (NC) service processors (primary and redundant)
One or two optional Powered Expansion Racks, each with 32U of rack space for up to
eight, 4U I/O Expansion Drawers. Redundant Bulk Power Assemblies (BPA) are located at
the top of the Powered Expansion Rack. Optional battery backup capability is available.
Each Powered Expansion Rack supports one 42U bolt-on, nonpowered Expansion Rack
for support of additional I/O drawers.
One or two nonpowered Expansion Racks, each supporting up to seven 4U I/O Expansion
Drawers.
One to 30 I/O Expansion Drawers (maximum of 12 RIO-2), each containing 20 PCI-X slots
and 16 hot-swap SCSI-3 disk bays.
In addition to the 24 inch rack-mountable I/O drawers, also available are standard, 2
meters high, 19 inch I/O racks for mounting both SCSI and SAS disk drawers. Each disk
drawer is individually powered by redundant, 220 V power supplies. The disk drawers can
be configured for either RAID or non-RAID disk storage. A maximum of 40 SCSI drawers
(each with 24 disks), and 185 SAS drawers (each with 12 disks), can be mounted in
19-inch racks. The maximum number of disks available in 19 inch racks is 960 hot-swap
SCSI disks (288 TB) and 2,220 hot-swap SAS disks (666 TB).
