Cisco UCS B440 High Performance Blade Server Installation and Service Note
OL-22475-01
Memory and Performance
Bandwidth and Performance
You can achieve maximum bandwidth, performance, and system memory using the following
configuration:
•
DDR3, 1066 millions of transfers per second (MT/s) across three Channels
•
8 DIMM per CPU (32 DIMMs)
•
Maximum capacity of 256 GB (using 8 GB DIMMs)
Note
The memory available for this server can only run at 1066 MHz.
Performance Loss
Performance is less than optimal if the following memory configurations are used:
•
Mixing DIMM sizes and densities within a pair
•
Unevenly populating DIMMs between CPUs
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:
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.
