Storage Area Networks (SANs)

A SAN (Storage Area Network) is a high-speed, high-bandwidth storage network that logically connects storage to servers. Of course, the SAN network is only as useful as the types of servers, storage hardware, connectivity hardware and management software that it can use.

Fibre Channel, an open industry standard, has emerged as the interconnect technology standard for SAN because of its suitability for storage networking. SAN topologies (switched fabric or arbitrated loops) extend the concepts offered by traditional server/storage connections and deliver more flexibility, availability, performance and allow integrated management.

Fibre Channel is a relatively new technology. The standards mentioned above have not yet been uniformly  adopted by the various vendors that are fielding "SAN solutions". As a result, at the present time there are few SAN solutions that can be regarded as truly "open".
