Memory Overview
Each node board supports 2 two to eight 240-pin DIMMs that can provide up to 32 GB of
ECC fully buffered DIMM (FBDIMM) DDR2-800 SDRAM (refer to
Figure 2-9
and
Figure 2-10
). Memory can be installed in both interleaved (dual-channel) and
non-interleaved (single-channel) configurations. All memory modules used to populate
the system should be the same size, type, and speed.
The node board memory controller supports memory mirroring to prevent data loss in
case of DIMM failure.
Note:
The memory mirroring feature is not enabled by default.
The system maintains two copies of all the data in memory; therefore, a mirrored system
uses only half of the installed DIMMs. If a DIMM fails, the system recovers the second
copy of data from the mirrored DIMM in the opposite channel. If both the primary and
the mirrored copy of the data become corrupt, the system memory will fail.
