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.
