1.5 SMP Expansion Module

The SMP Expansion Module is the central electronics complex that contains the processors, memory, L4 system cache, and respective controllers for these components. The base x440 system includes one SMP Expansion Module. Each SMP Expansion Module contains slots for up to four Xeon MP processors (or two Xeon DP processors) and 16 DIMMs.

There are two SMP Expansion Module part numbers for x440 models:

￿32P8340 is used in Xeon MP models. It is “unpopulated”, which means it does not contain any processors or memory. Any of the support Xeon MP processors can be installed in it.

￿71P7919 is used in Xeon DP models. It contains two 2.4 GHz Xeon DP processors and VRMs, and is used to upgrade a two-way Xeon DP x440 to a four-way configuration.

71P7919 is also compatible with Xeon MP processors. If you wish to upgrade your Xeon DP-based x440 to use Xeon MP processors, you can simply replace the processors and VRMs with supported Xeon MP processors.

Note: Information about the SMP Expansion Modules to be used in Gallatin-based systems (or existing systems you wish to upgrade to Gallatin processors) was not available at the time of publication.

The SMP Expansion Module is installed from the top of the server and mounts to the side of the centerplane using two levers on the top, as shown in Figure 1-10 on page 18. These same levers are used to remove the top of the SMP Expansion Module when adding additional processors or memory.
