What are Storage Area Networks?
Even the most complex technologies provide the most basic of functions. This is certainly true of Storage Area Networks (SANs). A Storage Area Network is a high-speed sub network of shared storage devices. A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN. As more storage devices are added to a SAN, they too will be accessible from any server in the larger network. A Storage Area Network can be anything from two servers on a network accessing a central pool of storage devices to several thousand servers accessing many millions of megabytes of storage.
