*  This value is  to use Memory mode with “BIOS PMem Performance Setting: Balanced Profile” .
Required BIOS version is listed in VMware Compatibility Guide.
 

Note:

• 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 amount available to ESXi because the system reserves some memory for internal use.
• App-Direct Mode is supported in vSphere 6.7 U3 and later.
• Memory Mode is supported in: vSphere 6.7 U3 and later.
