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:

CPU Cache Flush to NVDIMM Durability on Power Loss Capable

Memory Controller Flush to NVDIMM Durability on Power Loss Capable

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 U2 + Express Patch 10(ESXi670-201906002) or later.

Memory Mode is supported in

vSphere 6.5 U3 or later

vSphere 6.7 U2 + Express Path 10(ESXi670-201906002) or later

Earlier 6.7 releases are not supported.

Support Information

vSphere Support for Intel Optane Persistent Memory 100 Series

Persistent Memory certified servers with Intel Optane persistent memory 100 series and 2nd Gen Intel Xeon Scalable processors in select configurations, as documented in vSphere Support for Intel's Optane Persistent Memory (PMEM), are eligible for VMware support.

Balanced Profile optimizes Memory Mode performance by balancing the thresholds between DRAM and Intel Optane PMem to improve the bandwidth for all DRAM cache misses while maintaining the performance of DRAM cache hits. Balanced profile enabled BIOS has shown better performance in memory mode workloads.   For more information on balanced profile BIOS support, please contact your server vendor.

Dell Customer Advisory
BIOS version 2.9.2 or later is required to support Balanced Profile referenced in  vSphere Support for Intel's Optane Persistent Memory (PMEM).

Intel® Optane™ Persistent Memory 100 Series “Memory Mode” Production Deployment Advisory

Customers interested in using Intel’s Optane persistent memory 100 series in “Memory” mode on the above-certified OEM servers with configurations not published in  vSphere Support for Intel's Optane Persistent Memory (PMEM), must contact VMware to file an intent for production deployment request.

At present, production deployment of unpublished configurations requires explicit approval from VMware for support. VMware will continue to work with its customers and ecosystem to adjust the criteria for production deployments. For more information, customers should contact VMware representative.
