IBM BladeCenter HS23 13
If memory rank sparing is used, then two single-rank or dual-rank DIMMs must be installed per populated
channel (the DIMMs do not need to be 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.
Table 7 lists memory options available for the HS23 server. DIMMs can be installed one at a time, but for
performance reasons, install them in sets of four (one for each of the four memory channels).
