FusionServer 2288H V6 Server
Technical White Paper
5 Hardware Description
2022-06-25 49
For details about the AD and MM modes, see FusionServer PMem 200 User Guide .
⚫
For details about the capacity type of a single memory module, see "Search Parts" in the
Compatibility Checker .
⚫
The maximum number of memory modules supported depends on the memory type and
rank quantity.
Each memory channel supports a maximum of 8 ranks. The number of memory modules supported by
each channel varies depending on the number of ranks supported by each channel:
Number of memory modules supported by each channel ≤ Number of ranks supported by each memory
channel/Number of ranks supported by each memory module

5.1.4.2.4 DIMM Installation Rules
⚫
Observe the following when configuring PMem modules:
− The DDR4 memory modules used with the PMem modules include RDIMMs and
LRDIMMs.
− The PMem modules used in a server must have the same part number (P/N code).
− The DDR4 memory modules used with the PMem modules in a server must have
the same part number (P/N code).
⚫
Observe the following when configuring PMem modules in MM mode:
On the same server, it is recommended that the ratio of the DDR4 memory capacity to
the PMem capacity be 1:4 to 1:16.
