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
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block device, block-level data storage. SANs are primarily used to access Computer data storage, data storage devices, such as disk ...
(SAN)-attached storage devices.
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.
