DataPlow SAN File System is software that enables high-speed, yet secure, access to shared files located on SAN-attached storage devices. SFS is easy to manage, resilient to hardware failures, and simple to integrate into any environment. The following figure illustrates an SFS environment. Computers A, B, and C running DataPlow SFS connect to storage devices via the SAN. Additionally, computers B and C operate as NFS and/or CIFS file servers and extend file sharing to LAN-based computers D and E.
