NVMe host that runs the VMware ESXi operating system
VMware ESXi contains two levels of connectivity.
The first level of VMware ESXi is the host (ESXi machine), which is the actual server that includes the host bus adapter and the NVMe support. The host manages both hardware resource and virtualized components by using the GUI and CLI (esxcli).
The other level includes one or more guest virtual machines with an operating system. The virtual machines detect the defined volumes as VMware data stores and can read or write to them.
