Dell EMC NVDIMM-N Persistent Memory User Guide

Set up

Beginning with ESXi version 6.7 NVDIMM-N hardware is supported. The NVDIMM-N devices will be detected on startup with auto-generated namespaces. All NVDIMM-N devices will have capacity pooled into a single logical memory array for access by ESXi virtual machines.

NVDIMM-N Hardware is now supported on ESXi 6.7U1. Features and functionality should be identical to ESXi 6.7

Firmware requirements:

Table 1. Firmware requirementsThis table shows the firmware requirements.

Hardware requirements:

ESXi currently only supports NVDIMM-N hardware when the host system has an Intel Xeon™ Gold (51xx, 61xx) or Platinum (81xx) processor SKUs. Silver and Bronze SKUs are not sufficient for ESXi solution support at this time, but may be added in the future.

For BIOS Setup, default Persistent Memory settings can be used. However, both Non-Interleaved and Interleaved settings are supported by ESXi.

When adding a new VM to the ESXi host, follow these steps:
  1. Click on “Add other device” and select “NVDIMM” from the menu.
  2. Select the total capacity in MB of persistent memory you wish to expose to the VM.
    • Size should not exceed total NVDIMM-N capacity in the host system.
