IBM Xeon MP

The SMP Expansion Module is the central electronics complex (CEC) that contains the processors, memory, and level-4 system cache. Depending upon the model, the x440 system includes either one or two SMP Expansion Modules, each with sockets for up to four Intel Xeon MP Processors or up to two Xeon DP processors, 32 MB of XceL4 cache, and 16 DIMM slots. Although the Xeon DP and Xeon MP are similar in architecture, mixing of DP and MP in the same CEC or between two CECs is not supported.??By adding the second SMP Expansion Module, you can grow the 2-way or 4-way Xeon MP to an 8-way SMP or the 2-way Xeon DP to a 4-way SMP, while still retaining the 4U rack density. When adding the second CEC, you also get an additional 32 MB of XceL4 cache (for a maximum of 64 MB) and 16 more DIMM slots to support up to a maximum of 64 GB (using the 2 GB DIMMs, 32 GB in each CEC). The SMP Expansion Module is installed from the top of the server and easily mounts to the side of the centerplane using two... Minimize
