Choose DIMMs and Memory Mirroring
Select the memory configuration and whether or not you want the memory mirroring option.
The supported memory DIMMs and the mirroring option are listed in
Table 4.
The supported memory DIMMs in the UCS B200 M3 are listed in Table 4.
NOTE: When memory mirroring is enabled, the memory subsystem simultaneously
writes identical data to two adjacent channels. If a memory read from one of the
channels returns incorrect data due to an uncorrectable memory error, the system
automatically retrieves the data from the other channel. A transient or soft error in
one channel does not affect the mirrored data, and operation continues unless there
is a simultaneous error in exactly the same location on a DIMM and its mirrored
DIMM. Memory mirroring reduces the amount of memory available to the operating
system by 50% because only one of the two populated channels provides data.
