Notes:
  • All servers that support Intel Optane DC Persistent Memory supports the following NVDIMM Platform Capabilities:
    • Memory Controller Flush to NVDIMM Durability on Power Loss Capable
  • The ACPI Specification 6.2 defines in section 5.2.20.4 the NVDIMM Platform Capabilities: 
    1. CPU Cache Flush to NVDIMM Durability on Power Loss Capable
    2. Memory Controller Flush to NVDIMM Durability on Power Loss Capable
    3. Byte Addressable Persistent Memory Hardware Mirroring Capable
  • The certified maximum persistent memory capacity is based on installed memory capacity.  There is a small difference between installed persistent memory capacity and the amount available to ESXi because the system reserves some memory for internal use. 
  • App-Direct Mode is supported in vSphere 6.7 U2 + Express Patch 10(ESXi670-201906002) or later.
  • Memory Mode is not supported in Hewlett Packard Enterprise Superdome Flex Servers.

Support Information

HPE Customer Advisory
  1. All PMem implementations are required to perform integrity checks on PMem to ensure all errors are detected and reported before the OS can be allowed access to the PMem. PMem implementations differ on when and how such integrity checks are performed.  Hewlett Packard Enterprise Superdome Flex Server system BIOS will perform a PMem integrity check on boot when necessary, such as when a system reset is caused by a fatal error. Hewlett Packard Enterprise Superdome Flex Server System, the PMem integrity check may take up to 30 minutes depending on the amount of PMem memory installed in an HPE System.
  2. Following or greater version of Hewlett Packard Enterprise Superdome Flex Server BIOS is only recommended.
