IBM BladeCenter HS23E
13
If memory rank sparing is used, then two single-rank or dual-rank DIMMs or at least one quad-rank DIMM
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.
Chipkill, memory mirroring, and memory rank sparing modes are mutually exclusive. Only one operational
memory mode can be enabled on a server, and it is a system-wide setting.
Tables 8 lists memory options available for the HS23E server. DIMMs can be installed one at a time, but
for performance reasons, install them in sets of three (one for each of the three memory channels).
