Storage Devices

A subnetwork of storage devices that are connected with one another over a high speed network connection is Storage Area Network(SAN). It allows all designated users on the network to access multiple storage devices not only the storage devices installed within their computers. Once a SAN is constructed and all the storage devices are shared within the SAN, it is than connected to the servers that are accessed by network users. Large backup disk arrays can be stored on an off-site location and shared on a SAN where users can access them remotely. SANs are used for storage redundancy purposes in case of unexpected disaster and loss of data. A SAN typically supports data storage, retrieval and replication on business networks using high-end servers, multiple disk arrays and interconnect technology
