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.
Coda is a distributed file system developed as a research project at Carnegie Mellon University since 1987 under the direction of Mahadev Satyanarayanan. It descended directly from an older version of Andrew File System (AFS-2) and offers many similar features. The InterMezzo file system was inspired by Coda.
In this approach, a client requests and receives permission from multiple servers in order to read and write a replicated data. As an example, suppose in a distributed file system, a file is replicated on N servers. To update a file, a client must send a request to at least N/2 + 1 in order to make their agreement to perform an update. After ...
Some examples include: MapR File System (MapR-FS), Ceph-FS, Fraunhofer File System (BeeGFS), Lustre File System, IBM General Parallel File System (GPFS), and Parallel Virtual File System. MapR-FS is a distributed file system that is the basis of the MapR Converged Platform, with capabilities for distributed file storage, a NoSQL database with ...
Category for distributed file systems. Distributed file systems are network file systems where the server can be distributed across several physical computer nodes. File systems that share access to the same block storage are shared disk file systems.
A dataspace has two components: a bytestream and a set of key/value pairs. The bytestream is an ordered sequence of bytes, typically used to hold file data, and the key/value pairs are typically used to hold metadata. The object-based design has become typical of many distributed file systems including Lustre, Panasas, and pNFS.
In computer storage, a global file system is a distributed file system that can be accessed from multiple locations, typically across a wide-area network, and provides concurrent access to a global namespace from all locations. In order for a file system to be considered global, it must allow for files to be created, modified, and deleted from ...
The DCE Distributed File System (DCE/DFS) [1] is the remote file access protocol used with the Distributed Computing Environment. It was a variant of Andrew File System (AFS), based on the AFS Version 3.0 protocol that was developed commercially by Transarc Corporation.
