For details on the server hardware used in the DS8000, refer to IBM p5 570 Technical
Overview and Introduction, REDP-9117, available at:
http://www.redbooks.ibm.com
The symmetric multiprocessor (SMP) p5 570 system features 2-way or 4-way, copper-based,
SOI-based POWER5 microprocessors running at 1.5 GHz or 1.9 GHz with 36 MB off-chip
Level 3 cache configurations. The system is based on a concept of system building blocks.
The p5 570 processor complexes are facilitated with the use of processor interconnect and
system flex cables that enable as many as four 4-way p5 570 processor complexes to be
connected to achieve a true 16-way SMP combined system. How these features are
implemented in the DS8000 might vary.
One p5 570 processor complex includes:
Five hot-plug PCI-X slots with Enhanced Error Handling (EEH)
An enhanced blind-swap mechanism that allows hot-swap replacement or installation of
PCI-X adapters without sliding the enclosure into the service position
Two Ultra320 SCSI controllers
One10/100/1000 Mbps integrated dual-port Ethernet controller
Two serial ports
Two USB 2.0 ports
Two HMC Ethernet ports
Four remote RIO-G ports
Two System Power Control Network (SPCN) ports
The p5 570 includes two 3-pack front-accessible, hot-swap-capable disk bays. The six disk
bays of one IBM Server p5 570 processor complex can accommodate up to 880.8 GB of disk
storage using the 146.8 GB Ultra320 SCSI disk drives. Two additional media bays are used to
accept optional slim-line media devices, such as DVD-ROM or DVD-RAM drives. The p5 570
also has I/O expansion capability using the RIO-G interconnect. How these features are
implemented in the DS8000 might vary.
