Memory mirroring
If the server contains two or four memory boards with equal memory capacity, the system can be configured for memory mirroring. Using memory mirroring, the memory on one memory board in the server is mirrored by a second memory board. This reduces the overall available memory of the system to 50% of the total installed memory.
When a memory board or DIMM fault is detected on the primary memory board (in a mirrored pair), the secondary memory board takes over as primary until the failing board is replaced.
Hot removal of memory boards is supported when the server is configured for memory mirroring. The Memory Mirror LED on the memory board indicates that the board is in a memory mirrored configuration.
To configure memory mirroring:
1 During server startup, access the System Options Menu. (See “Starting your server” on page 16.)
2 Press the up and down arrow keys to select BIOS Setup Utility from the System Options Menu, then press ENTER. The BIOS Setup utility opens.
3 Press the up and down arrow keys to select Memory, then press ENTER. The Memory configuration menu opens.
4 Press the up and down arrow keys to select Configure System RAS and Performance, then press ENTER. The Configure System RAS and Performance screen opens.
