CONFIGURING the SERVER
Choose DIMMs and Memory Mirroring
Choose the memory configuration and whether or not you want the memory mirroring option.
The available memory DIMMs and mirroring option are listed in

Memory Mirroring Option
N01-MMIRROR
Approved Configurations
(1) 1-CPU configuration without memory mirroring:
Choose from one to six DIMMs (note that there are six DIMM slots per CPU)
■
(2) 1-CPU configuration with memory mirroring:
Choose either two or four DIMMs. The DIMMs will be placed by the factory as shown in the

NOTE: When memory mirroring is enabled, the memory subsystem simultaneously
writes identical data to two 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.
