Figure 32. Interleave sets while Interleaving is Disabled If Interleaving is Enabled in BIOS F2 setup, then the total NVDIMM-N capacity will be split into pools based on CPU socket. A total of two interleave sets will display with the aggregate capacity for the CPU socket displaying as one Interleave Set. Figure 33. Interleave sets while Interleaving is Enabled Datastore This is the Datastore area which includes information about the traditional storage accessible to ESXi and the persistent memory Datastore. NOTE: The PMEM Datastore is created on the first system boot after NVDIMM-Ns are detected in a system by ESXi. This datastore is fixed at that time and will not expand if additional NVDIMM-N modules are added after the fact. To expand the datastore: 1. Migrate your data. 2. Boot into BIOS F2 Setup. 3. Select Persistent Memory as indicated in section 5 of this guide. 4. Select Factory Default and Secure Erase for all NVDIMM-N modules in the system. 5. Follow prompts to reboot and continue on into ESXi. The additional NVDIMM-N modules will now be detected. 50 ESXi

Figure 32. Interleave sets while Interleaving is Disabled
If Interleaving is Enabled in BIOS F2 setup, then the total NVDIMM-N capacity will be split into pools based on CPU socket. A total of two
interleave sets will display with the aggregate capacity for the CPU socket displaying as one Interleave Set.

Datastore
This is the Datastore area which includes information about the traditional storage accessible to ESXi and the persistent memory
Datastore.
NOTE:
The PMEM Datastore is created on the first system boot after NVDIMM-Ns are detected in a system by ESXi.
This datastore is fixed at that time and will not expand if additional NVDIMM-N modules are added after the fact.
To expand the datastore:
1.
Migrate your data.
2.
Boot into BIOS F2 Setup.
3.
Select Persistent Memory as indicated in section 5 of this guide.
4.
Select Factory Default and Secure Erase for all NVDIMM-N modules in the system.
5.
Follow prompts to reboot and continue on into ESXi. The additional NVDIMM-N modules will now be detected.
