Detailed explanation-1: -A Storage Area Network (SAN) is a specialized, high-speed network that provides network access to storage devices. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols. SANs may span multiple sites.
Detailed explanation-2: -Unified SAN. A SAN is noted for its support of block storage, which is typical for enterprise applications. But file, object and other types of storage would traditionally demand a separate storage system, such as network-attached storage (NAS).
Detailed explanation-3: -Typically, the data transfer speeds of fibre-channel SAN storage start at around 4 Gbps, ranging up to 128 Gbps and faster. Speed varies by vendor and the type of SAN technology infrastructure, but the very latest storage fabric can now break 200 Gbps transfer rates.
