A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. As more storage devices are added to a SAN, they too will be accessible from any server in the larger network. In this case, the server merely acts as a pathway between the end user and the stored data.
Because stored data does not reside directly on any of a network's servers, server power is utilized for business applications, and network capacity is released to the end user.
