Altos G710 includes Memory Sparing and Mirroring support. These
features prevent a single memory module failure to occur and result in
a system crash.
Important:
Four DIMM population of completely identical
devices (two per channel) are required for memory mirroring and
sparing functionality (i.e., DIMM 1A, 1B, 2A, and 2B must be
identical) .
Memory sparing and mirroring configuration cannot be used
simultaneously.
Memory Sparing
To provide a more fault tolerant system, Altos G710 includes
specialized hardware to support fail-over to a spare DIMM device in
the event that a primary DIMM in use exceeds a specified threshold of
runtime errors. One of the DIMMs installed per channel will not be
used, but kept in reserve. In the event of significant failures in a
particular DIMM, it and its corresponding partner in the other channel
(if applicable), will, over time, have its data copied over to the spare
DIMM(s) held in reserve. When all the data has been copied, the
reserve DIMM(s) will be put into service and the failing DIMM will be
removed from service. Only one sparing cycle is supported. If this
feature is not enabled, then all DIMMs will be visible in normal address
space.
Refer to “Server Management Configuration” on page 103 for more
information about configuring the memory spare or mirror parameter
in the BIOS Setup utility.
