FusionServer 1288H V6 Server
Technical White Paper
5 Hardware Description
2022-06-25 37
Total memory capacity = Total capacity of all PMem modules (The DDR4 memory
modules are used as the cache and therefore are not calculated as memory capacity.)
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

5.4.2.4 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:
