Memory mirroring
Memory rank sparing
If memory mirroring is used, then DIMMs must be installed in pairs (minimum of one pair per processor), and both
DIMMs in a pair must be identical in type and size.
If memory rank sparing is used, then a minimum of one quad-rank DIMM or two single-rank or dual-rank DIMMs
must be installed per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of
a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs
installed.
The following table lists the memory options that are available for the x440 Compute Node.
