The DCPMM can work only in App Direct Mode (AD) and Memory Mode (MM).
The total supported memory capacity is calculated as follows:
− DCPMM in AD mode
Total memory capacity = Total capacity of all Total capacity of all
DDR4 memory modules
− DCPMM in MM mode
Total memory capacity = Total capacity of all DCPMMs (The DDR4 memory
modules are used as the cache and therefore are not calculated as memory
capacity.)
⚫ The total memory capacity cannot exceed the maximum memory capacity
supported by the CPUs.
⚫ For details about the AD and MM modes, see "Operating Modes" in FusionServer
DCPMM User Guide .
⚫
Use the Compatibility Checker to determine the capacity type of a single memory
module.

⚫ a: The maximum number of DCPMMs is based on dual-processor configuration.
The value is halved for a server with only one processor.
⚫ b: The maximum memory capacity varies depending on the CPU type and
DCPMM working mode. The value listed in this table is based on the assumption
that 12 DCPMMs and 12 DDR4 memory modules are used with the L series
CPUs and the DCPMMs work in AD mode.
