Distributed data store

A distributed file system (english distributed file system, DFS or network file system) is a special file system that is used to access files over a computer network and allows access and data storage on multiple servers as computers used. The counterpart of such a network file system is a classic local file system, which manages directly to the computer attached mass storage.

Implementations

Known implementations of distributed file systems are:

  • Distributed File System (DFS) as part of the operating system Windows by Microsoft
  • Originally developed at Carnegie Mellon University Andrew File System (AFS ), for which there are several manufacturers
  • DFS within the Distributed Computing Environment project ( DCE) of the consortium Open Software Foundation (now The Open Group ) as an evolution to AFS
  • Coda, also developed at Carnegie Mellon University
  • GlusterFS (all POSIX compliant operating systems )
  • HDFS Hadoop 's HDFS
  • Ceph (English): Provides Object, block and file storage, POSIX compliant, LGPL
