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:
“The following general definition of an animal: a system of different organic molecules that have combined with one another, under the impulsion of a sensation similar to an obtuse and muffled sense of touch given to them by the creator of matter as a whole, until each one of them has found the most suitable position for its shape and comfort.”
—Denis Diderot (1713–1784)
“As I look at the human story I see two stories. They run parallel and never meet. One is of people who live, as they can or must, the events that arrive; the other is of people who live, as they intend, the events they create.”
—Margaret Anderson (1886–1973)
“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)
“The individual protests against the world, but he doesn’t get beyond protest, he is just a single protester. When he wants to be more than that, he has to counter power with power, he has to oppose the system with another system.”
—Friedrich Dürrenmatt (1921–1990)
