Persistent Memory Components

Persistent Memory Modules

Persistent Memory Type	Module Description
Intel Optane Persistent Memory	128GB Intel Optane Persistent Memory 100 Series
	256GB Intel Optane Persistent Memory 100 Series
	521GB Intel Optane Persistent Memory 100 Series

Configuration Maximums

Server Model	Supported CPU Series	Certified Maximum Capacity in App-Direct Mode (TB)	Certified Maximum Capacity in Memory Mode (TB)
NF5280M5	Intel Xeon Platinum 8200 (Cascade Lake-SP) Intel Xeon Gold 6200/5200 (Cascade Lake-SP) Series	6	6

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 or later.
• Memory Mode is supported in
  • vSphere 6.7 U3 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/vSAN 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. 

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 the article 326910, vSphere/vSAN 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.

Inspur Support Advisory

Inspur BIOS 4.1.16 or later is required to support Balanced Profile referenced in KB vSphere/vSAN Support for Intel's Optane Persistent Memory (Pmem)
