A storage area network (SAN) is an architecture to attach remote computer data storage devices (such as disk arrays,
tape libraries, and optical jukeboxes) to servers so the devices appear as locally attached to the operating system.
A SAN typically has its own network of storage devices that are generally not accessible through the regular network
by regular devices.
A storage area network (SAN) is a high-speed special-purpose network (or subnetwork) that interconnects different kinds
of data storage devices with associated data servers on behalf of a larger network of users.
Typically, a storage area network is part of the overall network of computing resources for an enterprise.
