NO TICE
● A server must use the same model of DDR4 memory modules, and all the
memory modules operate at the same speed, which is the smallest value of:
● Memory speed supported by a processor
● Maximum operating speed of a memory module
● The DDR4 memory modules of
dierent types (RDIMM and LRDIMM) and
specications (capacity, bit width, rank, and height) cannot be used together.
● Contact your local Huawei sales representative or use the Intelligent
Computing Compatibility Checker to determine the components to be used.
● The memory can be used with Intel
®
Xeon
®
Scalable Skylake and Cascade
Lake processors. The maximum memory capacity supported varies depending
on the processor model.
– Skylake processors
▪ M processors: 1.5 TB/socket
▪
Other processors: 768 GB/socket
– Cascade Lake processors
▪
L processors: 4.5 TB/socket
▪
M processors: 2 TB/socket
▪
Other processors: 1 TB/socket
● The total memory capacity is the sum of the capacity of all DDR4 memory
modules.
NO TICE
The total memory capacity cannot exceed the maximum memory capacity
supported by the CPUs.
● Use the Intelligent Computing 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.
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
● A memory channel supports more than eight ranks for LRDIMMs.
