A Storage Area Network otherwise known as a SAN is a high speed network with a direct connection between different storage devices to servers and processors. Most (but not all) of the time the connection is through a Fibre Channel Switch. A SAN provides universal access to the enormous amount of information businesses are now creating. A SAN is separated into four main areas. The main areas include servers and storage devices, fabrics and connectivity, management, and exploitation and solutions.
SANs offer a simplified way to manage a company’s information storage capacity. They are scalable, flexible, enhance systems performance, and data is consistently available. They also offer integrated, real-time backup and recovery. By offering real-time backup and recovery, it reduces risks of companies losing their business information.
A SAN is similar yet different from a Local Area Net
To explain a SAN to a person who does not know much about Information Technology, it could be described as a virtual pool. Each individual server backs up and saves its data. The data then goes into a “virtual pool” where the SAN itself distributes and sorts the data appropriately. The SAN files the data so the user does not have to do it themselves. The pooled storage can be accessed by any device on the SAN as needed. This can actually increase the use capacity by up to 30% according to www.infrastor.com. Also, there is no limit to the amount of storage capacity you can add to a SAN. Storage devices can be added as needed to accommodate for the companies use. The physical storage then becomes a single, scalable resource available to the users of the SAN.
If a medium to large company was looking into storage options, a SAN would definitely be the best way to go. It would be in
