The VMware Host Client user interface provides information about the complex structure of the host-local PMem datastore. If you want to analyze this information and use it for troubleshooting and management purposes, you must be familiar with the concepts related to that complex structure.
- In the VMware Host Client user interface, modules represent the physical NVDIMMs that are connected to the motherboard of the host.
- In the VMware Host Client, you can check the health status of each module and identify unhealthy NVDIMM modules.
- Interleave Sets
Interleave sets are logical groupings of one or multiple modules. Interleave sets reveal how information is spread across the physical DIMMs and how
ESXi reads the information from the modules. Because
ESXi reads from each interleave set in turns, interleave sets ensure higher memory throughput.
For example, if an interleave set consists of two modules, ESXi reads the information from the two physical DIMMs in parallel and then proceeds with the next interleave set.
- The VMware Host Client user interface provides information about the way NVDIMMS are grouped into interleave sets.
