9-46 Upgrading Your Server
Memory Mirroring
The memory mirroring feature writes the same data into two groups of DIMMs corresponding with
each other between memory channels (channels 0 and 1) to provide data redundancy.
IMPORTANT:
The memory mirroring feature uses channels 0 and 1. In memory
mirroring configuration, the memory channel 2 of each CPU
(CPU1-DIMM3/6, CPU2-DIMM3/6) is disabled.
To use the Memory Mirroring feature, an additional memory stick
(N8102-392/393/394/395/396) is required.
NOTE:
The operating system only recognizes a half of the total
physical capacity.
