64 IBM ^ xSeries 440 Planning and Installation Guide
3.1 System hardware
The x440 provides a scalable and flexible hardware platform. There are a
number of important aspects of the system hardware to consider when planning
your configuration. These are discussed in this section.
3.1.1 Processors
There are currently two processor types available with the x440 system:
Xeon DP models can be ordered with either two Xeon DP processors in a
single SMP Expansion Module or with four Xeon DP processors in two SMP
Expansion Modules. There is no further upgrade beyond four Xeon DP
processors, other than replacing them with Xeon MP processors.
Xeon MP models come with two Xeon MP processors installed in the
standard SMP Expansion Module. Up to four Xeon MP processors are
supported in the standard SMP Expansion Module. Using the optional second
SMP Expansion Module, part number 32P8340, up to eight processors can
be installed in an x440.
Processors are available as options:
Xeon Processor MP 2.0 GHz 2 MB L3 Cache, 59P5173 (“Gallatin”)
Xeon Processor MP 1.9 GHz 1 MB L3 Cache, 59P5172 (“Gallatin”)
Xeon Processor MP 1.5 GHz 1 MB L3 Cache, 59P5171 (“Gallatin”)
Xeon Processor MP 1.6 GHz 1 MB L3 Cache, 32P8707 (“Foster”)
Xeon Processor MP 1.5 GHz 512 KB L3 Cache, 32P8706 (“Foster”)
Xeon Processor MP 1.4 GHz 512 KB L3 Cache, 32P8705 (“Foster”)
Xeon Processor DP 2.4 GHz 512 KB L2 Cache, 37L3533 (“Prestonia”)
Key processor configuration rules:
All CPUs used in a single-server (that is, two, four or eight-way) or
multi-server (eight, 12 or 16-way) configuration must be the same type,
speed, and L2/L3 cache size.
