DataPlow SAN File System
The SAN File System (SFS) is a high-performance, clustered file system created by the company DataPlow. SFS enables fast access to shared files located on shared, storage area network (SAN)-attached storage devices[1]. SFS utilizes the high-speed, scalable data transfers inherent to storage area networks and is a general-purpose file system for a wide variety of environments, including scientific computing, finance, healthcare, entertainment, defense, broadcast, and aerospace.
