IBM General Parallel File System
The General Parallel File System (GPFS) is a high-performance shared-disk clustered file system developed by IBM. It is used by many of the world's largest commercial companies, as well as some of the supercomputers on the Top 500 List. For example, GPFS is the filesystem of the ASC Purple Supercomputer which is composed of more than 12,000 processors and has 2 petabytes of total disk storage spanning more than 11,000 disks.
In common with typical cluster filesystems, GPFS provides concurrent high-speed file access to applications executing on multiple nodes of clusters. It can be used with AIX 5L clusters, Linux clusters, on Microsoft Windows Server, or a heterogeneous cluster of AIX, Linux and Windows nodes. In addition to providing filesystem storage capabilities, GPFS provides tools for management and administration of the GPFS cluster and allows for shared access to file systems from remote GPFS clusters.
GPFS has been available on IBM's AIX since 1998, on Linux since 2001 and on Microsoft Windows Server since 2008, and is offered as part of the IBM System Cluster 1350. The most recent release of GPFS 3.5 offers Active File Management to enable asynchronous access and control of local and remote files, thus allowing for global file collaboration.

Famous quotes containing the words general, parallel, file and/or system:
“No government can help the destinies of people who insist in putting sectional and class consciousness ahead of general weal.”
—Franklin D. Roosevelt (1882–1945)
“One writes of scars healed, a loose parallel to the pathology of the skin, but there is no such thing in the life of an individual. There are open wounds, shrunk sometimes to the size of a pin-prick but wounds still. The marks of suffering are more comparable to the loss of a finger, or the sight of an eye. We may not miss them, either, for one minute in a year, but if we should there is nothing to be done about it.”
—F. Scott Fitzgerald (1896–1940)
“I have been a soreheaded occupant of a file drawer labeled “Science Fiction” ... and I would like out, particularly since so many serious critics regularly mistake the drawer for a urinal.”
—Kurt Vonnegut, Jr. (b. 1922)
“Loving feels lonely in a violent world,
irrelevant to people burning like last year’s weed
with bellies distended, with fish throats agape
and flesh melting down to glue.
We can no longer shut out the screaming
That leaks through the ventilation system ...”
—Marge Piercy (b. 1936)
