Storage Area Networks (SAN)

Storage Area Networks

In order to provide high-speed, continuous access to multiple terabytes of data, a networking technology has emerged that is designed to overcome throughput and data-sharing issues common in existing data networks. Known as storage area networks (SAN), SANs incorporate a dedicated Fibre Channel (FC) network that connects one or more servers to storage devices. In more elaborate configurations, this dedicated network can also include switches, hubs, bridges and storage subsystems.

SANs provide a "behind the scenes" network that carries data-storage traffic, allowing traditional LANs to provide TCP/IP functionality. Separating these networks eliminates speed and bandwidth issues for both users and administrators.
