Configuring memory options
Memory sparing
The chipset on the system board in the server supports memory sparing, which can provide
a way to prevent data loss in case of DIMM failure. If a DIMM failure does occur, a DIMM
fault LED on the memory board will light orange to indicate the failed DIMM.
Using memory sparing, one rank (a pair of single-sided DIMMS or one double-sided DIMM)
on each memory board is used as a memory spare for another rank on the same memory
board. If a DIMM begins to fail, the contents of the failing DIMM is copied to the spare
DIMM rank on the same memory board. When all of the data is copied, the primary rank
is automatically removed from service. One DIMM rank is always maintained in reserve
and cannot be used by the operating system.
To configure memory sparing:
1
During server startup, access the System Options Menu. (See “Starting your server”
on page 16 .)
