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

App-Direct Mode

vSphere 6.7 EP10 enables Intel® Optane™ DC Persistent Memory in “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 Update 3 and 6.7 EP10 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 the “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

For specific limits for your server platform, please consult VMware Compatibility Guide (VCG).

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

For specific limits for your server platform, please consult VMware Compatibility Guide (VCG).

How do I get pre-approval to run Intel® Optane™ DC Persistent Memory in memory mode with vSphere?

Customer should contact a VMware representative. VMware representative will provide the formal approval from VMware to run this technology in memory mode with a specific customer’s configuration and use-cases. Please note, any deployment without formal approval will not be supported by VMware support teams.

Can I use vSAN with this technology?

VMware vSAN does not have support for “App-Direct” mode as cache or as a capacity tier device of vSAN. However, VSAN will work with vSphere host equipped with Intel Optane(TM) DC Persistent Memory in App-Direct mode.

Also, VSAN will work with Intel Optane(TM) DC Persistent Memory in Memory-mode as long as such deployments are pre-approved by VMware as mentioned above.
