Network File System (NFS) is a distributed file system protocol originally developed by Sun Microsystems (Sun) in 1984, [1] allowing a user on a client computer to access files over a computer network much like local storage is accessed.
Some researchers have made a functional and experimental analysis of several distributed file systems including HDFS, Ceph, Gluster, Lustre and old (1.6.x) version of MooseFS, although this document is from 2013 and a lot of information are outdated (e.g. MooseFS had no HA for Metadata Server at that time).
PNFS (Parallel NFS) – Clients available for Linux and OpenSolaris and back-ends from NetApp, Panasas, EMC Highroad and IBM GPFS; Coherent Remote File System (CRFS) – requires Btrfs; Parallel Optimized Host Message Exchange Layered File System (POHMELFS) and Distributed STorage (DST). POSIX compliant, added to Linux kernel 2.6.30
While 3Com was among the first firms to build a dedicated NAS for desktop operating systems, Auspex Systems was one of the first to develop a dedicated NFS server for use in the UNIX market. A group of Auspex engineers split away in the early 1990s to create the integrated NetApp FAS , which supported both the Windows SMB and the UNIX NFS ...

The NFS server is still supported in Windows Server 2012 R2. [17] [18] The NFS client feature and server features are separate from the SUA in Windows 7 and 2008, [19] and remained supported until Windows Subsystem for Linux replaced it. On desktop (Windows 7), NFS is only available in the Enterprise and Ultimate editions. [20]
A UNIX United system constructed with the Newcastle Connection is functionally indistinguishable from a centralised UNIX system at the system-call level. [ 4 ] In essence, the concept of the "parent directory" was re-interpreted at the root of the filesystem, where it originally had no significant meaning, to mean "this directory is on a remote ...
One of the first virtual file system mechanisms on Unix-like systems was introduced by Sun Microsystems in SunOS 2.0 in 1985. [2] It allowed Unix system calls to access local UFS file systems and remote NFS file systems transparently. For this reason, Unix vendors who licensed the NFS code from Sun often copied the design of Sun's VFS.
