Storage Area Network(SAN) is a high speed dedicated network that contains storage devices which are connected to the storage devices of the servers. The storage of data in SAN is done in the form of block level storage and file abstractions. SAN is different from other storage networks in the terms of ease of use, backup, optimized running of applications, storage management tasks. SAN reduces the excess amount of storage memory unlike other networks. There are different type of SAN topologies: Cascaded, Meshed, Ring, Skinny tree backbone, fat tree backbone, Single switch. Fiber Channel Arbitrated Loop is a mapping of Small Computer System Interface over fiber channel. All storage purpose devices can be attached to SAN.

SAN or Storage Area Network is a dedicated high-speed network or maybe a sub-network that connects and offers shared pools of storage devices to numerous servers. It transfers storage resources off the usual user network and rearranges them into a standalone, high-performance network. It permits every server to access shared storage just like an ordinary drive directly connected to the server.

When a host needs to access a storage device in the storage area network, a block-based access request is sent for the storage device. A SAN or storage area network is normally built using 3 standard components: switches, HBAs or host bus adapters, and cabling. Every storage system and switch in the storage area network should be interconnected and the physical interconnections should support bandwidth levels that are capable of sufficiently handling peak data activities.

Storage area networks or SANs are supervised centrally and Fibre Channel storage area networks are known to be intricate, hard to manage, and especially expensive.
