Bandwidth and Performance

You can achieve maximum bandwidth, performance, and system memory using the following

configuration:

•

The memory available for this server can only run at 1066 MHz.

Note

Performance Loss

Performance is less than optimal if the following memory configurations are used:

•

Depending on the application needed, performance loss might or might not be noticeable or measurable.

Partially populating a pair is unsupported, and will not work at all.

Installing an Adapter Card

The network adapters and interface cards all have a shared installation process. The following options

are available:

1.N20-AI0002, the Cisco UCS 82598KR-CI 10 Gb Ethernet Adapter, is not supported on this server but is still

available for other models. We suggest you use the Cisco UCS CNA M61KR-I Intel Converged Network Adapter

in place of the Cisco UCS 82598KR-CI 10 Gb Ethernet Adapter.

2. Requires UCS Manager 2.0(2) or later.

If you are switching from one type of card to another, before you physically perform the switch make

sure you have downloaded the latest device drivers and loaded them into the server's OS. For the most

recent details, refer to the firmware management chapter of one of the UCS Manager software

configuration guides.
