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.

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 AdvisoryBIOS 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 AdvisoryCustomers 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(PMEM), must contact VMware to file an intent for production deployment request.At present, production deployment of unpublished configurations requires explicit approval from VMware for support.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.Troubleshooting and Best Practices For more information on DELL EMC Intel® Optane™ DC Persistent Memory support see http://support.dell.com
