Memory Performance
When considering the memory configuration of the blade server, there are several things to consider. For example:
• When mixing DIMMs of different densities (capacities), the highest density DIMM goes in slot 1 then in descending density.
• Besides DIMM population and choice, the selected CPU(s) can have some effect on performance.
• DIMMs can be run in a 1DPC, a 2DPC, or a 3DPC configuration. 1DPC 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.
Furthermore, if memory mirroring is used, DRAM size is reduced by 50 percent for reasons of reliability.
Installing a Virtual Interface Card Adapter
The Cisco Virtual Interface Card (VIC) 1240 is a specialized adapter that provides dual 2 x 10 Gb of Ethernet/ or Fiber Channel over
Ethernet (FCoE) connectivity to each chassis. It plugs into the dedicated slot 1 connector only. It is currently the only card that can
be plugged into this connector and it will provide connectivity through either a 2100 series or 2200 series IOM.
Note You must remove the adapter card to service it.
To install a Cisco VIC 1340 or VIC 1240 in the blade server, follow these steps:
Procedure
Step 1 Position the VIC board connector above the motherboard connector and align the captive screw to the standoff post on
the motherboard.
Step 2
Firmly press the VIC board connector into the motherboard connector.
