Memory Sparing Feature
Memory Sparing feature puts a memory channel 2 of a memory controller in each CPU into standby status as
spare devices. If a correctable error occurs in a DIMM in the running memory controller, the feature
automatically changes the running DIMM from the failed one to a DIMM in the standby state to continue the
processing.
The following table shows configuration allowable for memory sparing and system logical memory capacity.
