Powered And Bolt On Frames - IBM p5 590 System Handbook

Both systems are powered by IBMs most advanced 64-bit Power Architecture
microprocessor, the POWER5 microprocessor, with simultaneous multi-threading
that makes each processor logically appear as two to the operating system, thus
increasing commercial throughput and system utilization over servers without
this capability. The p5-595 features a choice of IBMs fastest POWER5
microprocessors running at 1.9 GHz or 1.65 GHz, while the p5-590 offers
1.65 GHz processors.
For additional capacity, either a powered or non-powered frame can be
configured for a p5-595, as shown in Figure 1-2.

The p5-590 can be expanded by an optional bolt-on frame.
Every p5-590 and p5-595 server comes standard with Advanced POWER™
Virtualization, providing Micro-Partitioning, Virtual I/O Server, and Partition Load
Manager (PLM) for AIX 5L.
Micro-Partitioning enables system configurations with more partitions than
processors. Processing resources can be allocated in units as small as 1/10th of
a processor and be fine-tuned in increments of 1/100th of a processor. So a
p5-590 or p5-595 system can define up to ten
(maximum of 254 per system), controlled in a shared processor pool for
automatic, nondisruptive resource balancing. Virtualization features of the
