Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, allowing a user on a client computer to access files over a computer network much like local storage is accessed. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC) system. NFS is an open IETF standard. After the first experimental version developed in house at Sun Microsystems, all subsequent versions of the protocol are defined in a series of Request for Comments i.e. RFCs, allowing anyone to implement the protocol.
RFC 3530, April 2003 and again in
RFC 8881, August 2020) aims to provide protocol support to take advantage of clustered server deployments including the ability to provide scalable parallel access to files distributed among multiple servers (
pNFS extension). Version
4.1 includes Session trunking mechanism (Also known as NFS Multipathing) and is available in some enterprise solutions as
VMware ESXi.
