NVMeoF devices use the EUI prefix, or Extended Unique Identifier, and not the NAA or Network Addressing Authority. Either naming, however, is unique to that LUN. The storage device generates the NAA or EUI number. Since the NAA or EUI is unique to the LUN, that same naming is used across any ESXi hosts to which the device is presented. This scheme is what permits ESXi hosts to recognize the same datastore on that LUN, even if those hosts are in different vCenters (or standalone). Figure 3 shows how those FC-NVMe devices appear from within the vSphere Client and Figure 4 shows NVMe/TCP. They are not classified as (Dell) EMC disks, rather as NVMe. Like devices that are presented over FC and iSCSI, NVMeoF supports both the mobility ID and compatibility ID formats, each represented below.
