About the NFS Service

The NFS service enables systems of different architectures that run different operating systems to share file systems across a network.

The NFS environment can be implemented on different operating systems because NFS defines an abstract model of a file system rather than an architectural specification. Each OS applies the NFS model to its file system semantics. This model means that file system operations, such as reading and writing, function as though the operations are accessing a local file.

    The NFS service has the following benefits:

  • Enables multiple systems to use the same files so that everyone on the network can access the same data

  • Reduces storage costs by having systems share applications instead of requiring local disk space for each user application

  • Provides data consistency and reliability because all users can read the same set of files

  • Makes mounting of file systems transparent to users

  • Makes accessing of remote files transparent to users

  • Supports heterogeneous environments

  • Reduces system administration overhead

The NFS service makes the physical location of a file system irrelevant to the user. Instead of having to place commonly used files on every system, you can share the original file from the NFS server's file system. All other systems access the files across the network. Under NFS operation, remote file systems are almost indistinguishable from local file systems.
