Scale out File Services (SoFS) is a highly-scalable NAS-grid solution developed by IBM. It is based on IBM's high-performance shared-disk clustered file system GPFS which is used in many of the [http://www.top500.org/ Top 500 Supercomputing Sites] . SoFS exports the clustered file system through industry standard protocols like CIFS, NFS, FTP and HTTP.An outstanding feature of SoFS is that all nodes in the grid export all files of all file systems (up to 256) simultaneously. Most other so-called clustered NAS solutions pin individual files to a single node thus limiting the single file performance dramatically. Each file system scales up to the multi-Petabyte range.

SoFS combines proprietary IBM technology (storage & server hardware and GPFS) with open source components like Linux, Samba and [http://ctdb.samba.org CTDB] .
