FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Storage-area network (SAN): A network infrastructure designed to support file servers and provide data storage, retrieval, and replication. It involves high-end servers, multiple disk arrays (called blocks), and Fibre Channel interconnection technology.

Detailed explanation-2: -A storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.

Detailed explanation-3: -SAN and network-attached storage (NAS) are both network-based storage solutions. A SAN typically uses Fibre Channel connectivity, while NAS typically ties into to the network through a standard Ethernet connection. A SAN stores data at the block level, while NAS accesses data as files.

Detailed explanation-4: -Through the host adapters the operating system of the server can communicate with the storage devices in the SAN. In Fibre channel deployments, a cable connects to the host adapter through the gigabit interface converter (GBIC).

Detailed explanation-5: -A SAN switch is hardware that connects servers to shared pools of storage devices. It is dedicated to moving storage traffic in a SAN.
