On February 17, 2015 IBM rebranded GPFS as IBM Spectrum Scale.
The General Parallel File System (GPFS) is a high-performance clustered file system developed by IBM. It can be deployed in shared-disk or shared-nothing distributed parallel modes. 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 was the filesystem of the ASC Purple Supercomputer which was 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 Windows Server since 2008, and it is offered as part of the IBM System Cluster 1350. GPFS 3.5 introduced Active File Management to enable asynchronous access and control of local and remote files, thus allowing for global file collaboration. The most recent version GPFS 4.1 introduces encryption. IBM also sells GPFS as IBM Spectrum Scale, a branding for Software-Defined Storage (SDS).
GPFS began as the Tiger Shark file system, a research project at IBM's Almaden Research Center as early as 1993. Shark was initially designed to support high throughput multimedia applications. This design turned out to be well suited to scientific computing.
