Processor Configuration Rules - IBM p5 590 System Handbook

Logical partitions must be populated with the following minimum set of system
resources
– One dedicated processor or 0.1 processing unit.
– 128 MB memory
– Physical or virtual storage adapter (SCSI card)
– Physical or virtual network adapter
Keep in mind the following limitations regarding Micro-Partitioning:
Shared processor partitions must be configured with at least 0.1 processing
units of a physical processor
The number of shared processor partitions for a system depends on the
number of active processors in a system
p5-590 and p5-595 systems support up to 254 partitions
Each logical partition supports a maximum of 64 virtual processors
Mixing dedicated and shared processors within the same partition is not a
supported configuration

5.2.3 Processor configuration rules

The p5-590 can be populated with one or two POWER5 standard (1.65 GHz)
16-way processor books. The p5-595 can be populated with up to four POWER5
16-way processor books. Each processor book contains two 8-way multi-chip
modules. Each 8-way MCM contains four dual core processor chips.
The following list outlines configuration features specific to the MCM processor
books on the p5-590 and p5-595.
Each pair of processors is supported by 1.9 MB of Level 2 cache and 36 MB
of Level 3 (L3) cache
Processor books are available two speeds: standard (1.65 GHz) and turbo
(1.9 GHz)
Processor books must operate at the same speed
For both p5-590 and p5-595, each processor book provides sixteen memory
card slots and six slots for RIO-2 dual loop adapters for attachment of I/O
drawers
One Multiplexer Card (FC 7812) is required for each processor book to
provide a communication channel between the individual processor book and
the system service processors
