HS20 - 7981 memory options
Notes:
1.
The memory subsystem is a 2-way interleaved subsystem; memory must be populated in pairs of 2
identical DIMMs. The two members of the pair must be matched, but the sets do not have to be matched.
2. DIMMs should be installed in the following order: DIMMs 1 & 2 (Pair 1), DIMMs 3 & 4 (Pair 2).
3. BladeCenter HS20-7981 will support Hot Spare Memory and Memory mirroring. Hot Spare Memory and
Memory mirroring require 4 identical DIMMS (2 identical pairs).
4. Chipkill function is supported when all four slots have chipkill memory installed.
