The VSP One File server supports all clients compliant with
NFS v2, v3, v4, and v4.1 standards. NFS v2, v3, v4, and v4.1 are supported over TCP.
The following table summarizes the supported versions of NFS and other UNIX
protocols:
| Protocol | Supported versions |
|---|---|
| NFS | v2, v3, v4, and v4.1 |
| Port Mapper | v2 |
| Mount | v1 and v3 |
| Network Lock Manager (NLM) | v1, v3, and v4 |
| Network Status Monitor (NSM) | v1 |
CAUTION:
While it is possible to use UDP with NFS on versions 2 and 3, it is not recommended due to inherent risks. On the VSP One File server, UDP is not automatically presented as a transport option for the NFS service by the Port Mapper service.
