Storage Area Network
SAN

    (SAN) A high-speed subnetwork of shared storage
   devices.  A storage device is a machine that contains nothing
   but a disk or disks for storing data.

   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.  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 used for business
   applications, and network capacity is released to the end
   user.
