2. Storage Area Network or SAN is a high-speed, special purpose, dedicated network that supports communications between computers and storage servers in support of data-intensive applications such as inventory management, credit and billing management, receivables management, customer relationship management, and supply chain management.

A SAN is much more complex than simple network-attached storage (NAS) and provides application users with much faster access to databases, SANs also provide for centralized management of critical data, including accessibility, security, and backup.


2. In computing, a storage area network (SAN) is an architecture to attach remote computer storage devices (such as disk arrays, tape libraries and optical jukeboxes) to servers in such a way that, to the operating system, the devices appear as locally attached.
