Scale out File Services (SoFS) is a highly-scalable, grid-based NAS solution developed by IBM. It is based on IBM's high-performance shared-disk clustered file system GPFS. SoFS exports the clustered file system through industry standard protocols like CIFS, NFS, FTP and HTTP. Released in 2007, SoFS is a second generation file services architecture first used within IBM to store employees files since 2001. All of the SoFS nodes in the grid export all files of all file systems simultaneously. This is a different approach from some other clustered NAS solutions which pin individual files to a single node or pair of nodes thus limiting the single file performance dramatically. Each file system can be multiple Petabytes in size.
