VMware is pleased to announce the support for Intel® Optane™ DC persistent memory technology codenamed “Apache Pass” in “App-Direct” mode as well as “Memory” mode.

App-Direct Mode

vSphere 6.7 EP05 (ESXi670-201811001) enables Intel® Optane™ DC Persistent Memoryin “App-Direct” mode. Customers are free to take advantage of the large capacity, affordability and persistence benefits offered in this mode and deploy in production any supported 3rd party application without any restriction with full VMware support. VMware encourages its customers to leverage this technology in “App-Direct” mode.

Memory Mode

VMware vSphere 6.5 EP13 (ESXi650-201903001) and 6.7 EP05 enable Intel® Optane™ DC Persistent Memory in “Memory” mode. VMware vSphere usage of Intel® Optane™ DC Persistent Memory in “Memory mode” can offer increased memory capacity and TCO improvements for relevant customer workloads. Initially, VMware will support “Memory” mode for limited use-cases in production deployments; such a deployment requires “explicit approval” from VMware for support. For more information, customers should contact their VMware representative.

 

Where do I find the vSphere compatible server hardware for this technology?

To find the compatible servers with this technology, please consult VMware Compatibility Guide (VCG). VMware VCG lists compatible servers for this technology under “Persistent Memory” feature. Please consult the associated KB article for more specific configuration and technology compatibility, listed under footnote on VCG listing. If you don’t see the server of your choice in the list, please contact your server vendor for the availability.

What specific editions of vSphere support this technology?

vSphere Enterprise Plus Edition™ and higher version only.

What is the maximum host capacity of Intel® Optane™ DC Persistent Memory enabled in vSphere?

Specific limits of Intel® Optane™ DC Persistent Memory available on specific OEM server SKUs is listed on VMware Compatibility Guide (VCG). vSphere is certifying the following maximum capacity for vSphere 6.7 release as follows:

  • Up to 6TB for 2-socket and 12TB for 4-socket of Intel® Optane™ DC Persistent Memory in memory mode
  • A combination of DRAM and Intel® Optane™ DC Persistent Memory in App-Direct mode with a combined limit of 6TB for 2-socket and 12TB for 4-socket

What is the maximum VM capacity of Intel® Optane™ DC Persistent Memory enabled in vSphere?

A VM can be configured with the following limits in various configurations:

  • Up to 6TB of virtual RAM backed-up by Intel® Optane™ DC Persistent Memory in memory mode
  • Up to 6TB of virtual RAM and vNVDIMM in total, where vNVDIMM is backed-up by Intel® Optane™ DC Persistent Memory in App-Direct mode

Can I use vSAN with this technology?

VMware vSAN will not have support for “App-Direct” mode at this time as cache or capacity tier devices of vSAN and will have separate communication when ready. For “Memory Mode” support for vSAN on vSphere 6.7 and vSphere 6.5, a customer needs to file the above-listed intent of production deployment request.
