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.

Tip: For the latest hints and tips on the x440, review the document Hints, Tips, and Frequently Asked Questions for the xSeries 440 Quick Reference, available from:

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.
