In computing, a distributed file system (DFS) or network file system is any file system that allows access from multiple hosts to files shared via a computer network.This makes it possible for multiple users on multiple machines to share files and storage resources.
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. NFS, like many other protocols, builds on the Open Network Computing Remote Procedure Call (ONC RPC
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
Network-attached storage typically provide access to files using network file sharing protocols such as NFS, SMB, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files among multiple computers, as well as to remove the responsibility of file serving from other servers on the network; by doing ...

With the StorNext file system installed, these computers can read and write to the same storage volume at the same time enabling what is known as a "file-locking SAN." StorNext is used in environments where large files must be shared, and accessed simultaneously by users without network delays, or where a file must be available for access by ...
Shared-disk file systems (also called shared-storage file systems, SAN file system, Clustered file system or even cluster file systems) are primarily used in a storage area network where all nodes directly access the block storage where the file system is located. This makes it possible for nodes to fail without affecting access to the file ...
CacheFS is a family of software technologies designed to speed up distributed file system file access for networked computers. [citation needed] They store copies of files on secondary memory, typically a local hard disk, so that if a file is accessed again, it can be fetched locally at much higher speeds than networks typically allow.
