Processor Options - IBM System x3850 X5 Implementation Manual

Having only one processor installed in the HX5 instead of two processors is supported;
however, the recommendation is for two processors to maximize memory performance.
Ensure that all firmware is up-to-date before attaching the MAX5 to the blade. For minimum
firmware requirements, see 8.2.3, "Required firmware of each blade and the AMM" on
page 379.
When inserting an HX5 with MAX5, there is no partition information to set up in a scalable
complex. MAX5 ships ready to use when attached.

5.9 Processor options

The HX5 type 7872 supports Intel Xeon 6500 and 7500 quad-core, 6-core, or 8-core
processors. The Intel Xeon processors are available in various clock speeds and have
standard and low-power offerings. To see a list of processor features that are included in the
Intel Xeon 6500 and 7500 series, see 2.2, "Intel Xeon 6500 and 7500 family processors" on
page 16.
Table 5-11 lists the processor options for the HX5 and the supported models.
