No VMware?
Datrium's claim of not having VMware support will be news to VMware, considering they've had support and drivers for NVMe for at least two releases (http://www.nvmexpress.org/vmware/).
The question itself about whether NVMe-oF (the correct abbreviation, by the way) is a SAN is like asking whether or not a shipping container is a ship or not. NVMe (and NVMe-oF) are protocols, and a SAN is an implementation of those protocols.
Fibre Channel is a prime example of how the protocol itself can be configured as a SAN, as a Point-to-Point, or as an Arbitrated Loop. NVMe over Fabrics falls in that same realm of "implementation strategies" which *could* be a SAN, or it *could* be a DAS device, etc.
This becomes incredibly important when weighing and measuring the pros and cons of the protocol (NVMe-oF) over the transport mechanism (RDMA-based) versus the architecture type (SAN, NAS, DAS, etc.).
Disclosure: I am on the Boards of Directors for NVM Express, SNIA, and FCIA, but speak only for myself.
