'''Grid-oriented Storage (GOS)''' is a dedicated data storage architecture which can be connected directly to a computational grid to support advanced data bank services and reservoirs for data that can be shared among multiple computers and end users on the grid.

'''Grid-oriented Storage''' ('''GOS''') was a term used for data storage by a university project during the era when the term [[grid computing]] was popular.

== Description ==

GOS iswas a successor of well-usedthe term [[network-attached storage]] (NAS) products in the [[Grid Computing]] era. A GOS-specific File System (GOS-FS), a [[Peer-to-peer|P2P]] clustering technique, the single-purpose intent of a GOS operating system (OS), and a browser-based management console motivate and enable this new architecture. GOS is the first demonstration that Office/database/Web/media applications can be accelerated by tenfold in real-world tests. GOS systems usually contain one or morecontained hard disks, often arranged into logical, redundant storage containers or [[RAID]]s (redundant arrays of independent disks), as dolike traditional file servers.

GOS was designed to deal with long-distance, cross-___domain and single-image file operations, which is typical in Grid environments. GOS behaves like a file server via the file-based GOS-FS protocol to any entity on the grid. Similar to [[Advanced Resource Connector|GridFTP]], GOS-FS integrates a parallel stream engine and [[Grid Security Infrastructure]] (GSI).

GOS is designed to deal with long-distance, cross-___domain and single-image file operations, which is typical in Grid environments. GOS behaves like a file server via the file-based GOS-FS protocol to any entity on the grid. Inspired by the success of [[Advanced Resource Connector|GridFTP]], GOS-FS integrates a parallel stream engine and [[Grid Security Infrastructure]] (GSI). Conforming to the universal VFS (Virtual Filesystem Switch), GOS-FS can be pervasively used as an underlying platform to best utilize the increased transfer bandwidth and accelerate the [[Network File System (protocol)|NFS]]/[[CIFS]]-based applications. GOS can also run over [[SCSI]], [[Fibre Channel]] or [[iSCSI]], which does not affect the acceleration performance, offering both file level protocols and block level protocols for [[Storagestorage Areaarea Networknetwork]] (SAN) from the same system.

Centralized management techniques for these resources are limited in their scalability both in terms of execution efficiency and fault tolerance. Provision of services across such platforms requires a distributed resource management mechanism and the [[Peerpeer-to-peer|P2P]] clustered GOS appliances allow a single storage image to continue to expand, even if a single GOS appliance reaches its capacity limitations. The cluster shares a common, aggregate presentation of the data stored on all participating GOS appliances. Each GOS appliance manages its own internal storage space. The major benefit of this aggregation is that clustered GOS storage can be accessed by users as a single mount point.

GOS products fit the thin-server categorization. Compared with traditional “fat server”-based storage architectures, thin-server GOS appliances deliver numerous advantages, such as the alleviation of potential network/grid bottle-necks, CPU and OS optimized for I/O only, ease of installation, remote management and minimal maintenance, low cost and Plug and Play, etc. Examples of similar innovations include NAS, printers, fax machines, routers and switches.

== History ==

Grid-oriented Storage (GOS) was proposed by [[Frank Zhigang Wang|Prof. Frank Wang]] and Dr. Na Helian in 2003 inproposed a funding proposal, to the UK government titled “Grid-Oriented Storage (GOS): Next Generation Data Storage System Architecture for the Grid Computing Era”, toin the UK government2003. The proposal was approved and granted one million pounds{{citation needed|date=March 2009}} in 2004. The first prototype was constructed in 2005 at Centre for Grid Computing, Cambridge-Cranfield High Performance Computing Facility. The first conference presentation was at IEEE Symposium on Cluster Computing and Grid (CCGrid), 9–12 May 2005, Cardiff, UK. As one of the five best work-in-progress, it was included in the IEEE Distributed Systems Online. In 2006, the GOS architecture and its implementations was published in IEEE Transactions on Computers, titled “Grid-oriented Storage: A Single-Image, Cross-Domain, High-Bandwidth Architecture”. From
