Memory Performance
When considering the memory configuration of your blade server, there are several things you need to consider. For example:
•
When mixing DIMMs of different densities, the highest density DIMM goes in slot 1 then in descending density.
•
Your selected CPU(s) can have some affect on performance.
•
DIMMs can be run in a 1DPC, a 2DPC, or a 3DPC configuration. 1 DPC and 2DPC can provide the maximum rated speed that
the CPU and DIMMs are rated for. 3DPC causes the DIMMs to run at a slower speed.
Memory Mirroring and RAS
The Intel CPUs within the blade server support memory mirroring only when an even number of Channels are populated with DIMMs.
If one or three channels are populated with DIMMs, memory mirroring is automatically disabled. Furthermore, if memory mirroring
is used, DRAM size is reduced by 50 percent for reasons of reliability.
