Huawei FusionServer Pro 5288 V5 - Memory Compatibility

5.4.2.3 Memory Compatibility
Observe the following rules when conguring DC persistent memory modules
(DCPMMs):
NO TICE
● The DCPMMs must be used with the DDR4 memory modules. For details, see
Huawei FusionServer Pro DCPMM User Guide .
● Contact your local Huawei sales representative or use the Computing Product
Compatibility Checker to determine the components to be used.
● The memory must be used with Intel
®
Xeon
®
Scalable Cascade Lake
processors. The maximum memory capacity supported varies depending on
the processor model.
– L processors: 4.5 TB/socket
– M processors: 2 TB/socket
– Other processors: 1 TB/socket
● 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 DCPMMs + 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.)
NO TICE
● 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
Huawei FusionServer Pro DCPMM User Guide .
● Use the Computing Product Compatibility Checker to determine the
capacity type of a single memory module.
● The maximum number of memory modules supported by a server varies
depending on the CPU type, memory type, rank quantity, and operating
voltage.
