SAN

SAN stands for Storage Area Network. A SAN is a high performance dedicated network storage subsystem that is connected to the backend of servers. A SAN liberates storage devices, so they are not on any one particular server bus, and attaches them directly on the network subsystem via network processors. The result is that a SAN architecture makes all storage devices accessible to all servers on the network. Many believe that SAN's will become the standard architecture for enterprise-wide network storage in the near future.
