Distributed file systems may aim for "transparency" in a number of aspects. That is, they aim to be "invisible" to client programs, which "see" a system which is similar to a local file system. Behind the scenes, the distributed file system handles locating files, transporting data, and potentially providing other features listed below.
Google, one of the biggest internet companies, has created its own distributed file system, named Google File System (GFS), to meet the rapidly growing demands of Google's data processing needs, and it is used for all cloud services. GFS is a scalable distributed file system for data-intensive applications.
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.
Hadoop Distributed File System (HDFS) – a distributed file-system that stores data on commodity machines, providing very high aggregate bandwidth across the cluster; Hadoop YARN – (introduced in 2012) is a platform responsible for managing computing resources in clusters and using them for scheduling users' applications; [10] [11]
The OneFS File System is a proprietary file system that can only be managed and controlled by the FreeBSD-derived OneFS Operating System. [3] zsh is the default login shell of the OneFS Operating System. OneFS presents a specialized command set to administer the OneFS File System. [6] Most specialized shell programs start with letters isi.
LizardFS is an open source distributed file system that is POSIX-compliant and licensed under GPLv3. [3] [4] It was released in 2013 as fork of MooseFS. [5]LizardFS is also offering a paid technical support (Standard, Enterprise and Enterprise Plus) with possibility of configurating and setting up the cluster and active cluster monitoring.
The Lustre file system architecture was started as a research project in 1999 by Peter J. Braam, who was a staff of Carnegie Mellon University (CMU) at the time. Braam went on to found his own company Cluster File Systems in 2001, [27] starting from work on the InterMezzo file system in the Coda project at CMU. [28]
A parallel file system is a type of distributed file system that distributes file data across multiple servers and provides for concurrent access by multiple tasks of a parallel application. PVFS was designed for use in large scale cluster computing .
