XtreemFS
XtreemFS is an object-based, distributed file system for wide area networks.F. Hupfeld, T. Cortes, B. Kolbeck, E. Focht, M. Hess, J. Malo, J. Marti, J. Stender, E. Cesario"XtreemFS - a case for object-based storage in Grid data management" VLDB Workshop on Data Management in Grids. In: Proceedings of 33rd International Conference on Very Large Data Bases (VLDB) Workshops, 2007. XtreemFS' outstanding feature is full (all components) and real (all failure scenarios, including network partitions) fault tolerance, while maintaining POSIX file system semantics. Fault-tolerance is achieved by using Paxos-based lease negotiation algorithms and is used to replicate files and metadata. SSL and X.509 certificates support make XtreemFS usable over public networks. XtreemFS has been under development since early 2007. A first public release was made in August 2008. XtreemFS 1.0 was released in August 2009. The 1.0 release includes support for read-only replication with failover, data cent ...

List Of File Systems
The following lists identify, characterize, and link to more thorough information on file systems. Many older operating systems support only their one "native" file system, which does not bear any name apart from the name of the operating system itself. Disk file systems Disk file systems are usually block-oriented. Files in a block-oriented file system are sequences of blocks, often featuring fully random-access read, write, and modify operations. * ADFS – Acorn's Advanced Disc filing system, successor to DFS. * AdvFS – Advanced File System, designed by Digital Equipment Corporation for their Digital UNIX (now Tru64 UNIX) operating system. * APFS – Apple File System is a file system for Apple products. * AthFS – AtheOS File System, a 64-bit journaled filesystem now used by Syllable. Also called AFS. * BFS – the Boot File System used on System V release 4.0 and UnixWare. * BFS – the Be File System used on BeOS, occasionally misnamed as BeFS. Open source impl ...

Network File Systems
A clustered file system (CFS) is a file system which is shared by being simultaneously Mount (computing), mounted on multiple Server (computing), servers. There are several approaches to computer cluster, clustering, most of which do not employ a clustered file system (only direct attached storage for each node). Clustered file systems can provide features like location-independent addressing and redundancy which improve reliability or reduce the complexity of the other parts of the cluster. Parallel file systems are a type of clustered file system that spread data across multiple storage nodes, usually for redundancy or performance. Shared-disk file system A shared-disk file system uses a storage area network (SAN) to allow multiple computers to gain direct disk access at the Block (data storage), block level. Access control and translation from file-level operations that applications use to block-level operations used by the SAN must take place on the client node. The mos ...

Paxos (computer Science)
Paxos is a family of protocols for solving consensus in a network of unreliable or fallible processors. Consensus is the process of agreeing on one result among a group of participants. This problem becomes difficult when the participants or their communications may experience failures. Consensus protocols are the basis for the state machine replication approach to distributed computing, as suggested by Leslie Lamport and surveyed by Fred Schneider. State machine replication is a technique for converting an algorithm into a fault-tolerant, distributed implementation. Ad-hoc techniques may leave important cases of failures unresolved. The principled approach proposed by Lamport et al. ensures all cases are handled safely. The Paxos protocol was first submitted in 1989 and named after a fictional legislative consensus system used on the Paxos island in Greece, where Lamport wrote that the parliament had to function "even though legislators continually wandered in and out of ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

BeeGFS
BeeGFS (formerly FhGFS) is a parallel file system developed for high-performance computing. BeeGFS includes a distributed metadata architecture for scalability and flexibility reasons. It specializes in data throughput. BeeGFS was originally developed at the Fraunhofer Center for High Performance Computing in Germany by a team led by Sven Breuner. Breuner later became the CEO of ThinkParQ (2014–2018), the spin-off company that was founded in 2014 to maintain BeeGFS and offer professional services. While the Community Edition of BeeGFS can be downloaded and used free of charge, the Enterprise Edition must be used under a professional support subscription contract. History and usage BeeGFS started in 2005 as an in-house development at Fraunhofer Center for HPC to replace the existing file system on the institute's new compute cluster and to be used in a production environment. In 2007, the first beta version of the software was announced during ISC07 in Dresden, Germany and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grid Computing
Grid computing is the use of widely distributed computer resources to reach a common goal. A computing grid can be thought of as a distributed system with non-interactive workloads that involve many files. Grid computing is distinguished from conventional high-performance computing systems such as cluster computing in that grid computers have each node set to perform a different task/application. Grid computers also tend to be more heterogeneous and geographically dispersed (thus not physically coupled) than cluster computers. Although a single grid can be dedicated to a particular application, commonly a grid is used for a variety of purposes. Grids are often constructed with general-purpose grid middleware software libraries. Grid sizes can be quite large. Grids are a form of distributed computing composed of many networked loosely coupled computers acting together to perform large tasks. For certain applications, distributed or grid computing can be seen as a special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
