ABSTRACT
As we are moving to a new global world where the essence of storing the data plays a vital role in handling many computer related projects and in many other fields. This global age is mainly grounded by the internet and the way we handle our own networks.
Traditionally, data storage resides on hard disks that are locally attached to individual servers. This is known as Direct Attached Storage (DAS). A Storage Area Network (SAN) is a separate “network” dedicated to storage devices and at minimum consists of one (or more) large banks of disks mounted in racks that provide for ‘shared’ storage space which is accessible by many servers/systems. A SAN functions as a high-speed network similar to a conventional local area network (LAN) and establishes a direct connection between storage resources and the file server infrastructure.
