Intel Optane PMem 200 Series
•
Mode definitions: AD = App Direct Mode, MM = Memory Mode, AD+MM = Mixed Mode
•
No mixing of PMem and NVDIMMs within the platform.
•
For MM, NM/FM ratio is between 1:4 and 1:16. The capacity not used for FM can be used
for AD. (NM = Near Memory; FM = Far Memory).
•
Matrix targets configs for optimized PMem to DRAM cache ratio in MM and MM + AD
modes.
•
For each individual population, different PMem rearrangements among channels are per
-
mitted so long as the configuration doesn’t break X12 DP Memory population rules.
•
Ensure the same DDR4 DIMM type and capacity are used for each DDR4 + PMem popu-
lation.
•
If the system detects an unvalidated config, then the system issues a BIOS warning. The
CLI functionality is limited in non POR configurations, and select commands will not be
supported.
Note
: PMem 200 Series are supported on 3rd Gen Intel Xeon Scalable Platinum, Gold and
selected Silver processors. PMem may only be supported under certain conditions, please
contact Supermicro technical support for additional information.
