Demand for data storage and availability is growing rapidly across the commercial business and other sectors. Traditional server-attached storage is often tough to centrally manage or update. SAN is networked arranged device designed to provide high-performance, flexible, and highly scalable storage environments. It is cost effective and plays a vital part in today’s businesses and offers many advantages over conventional server involved storage applications. SAN is adjusted for high-volume block-oriented data transfers. It fulfills the need to eliminate direct storage-to-server links and helps getting more flexible storage access. It follows open industry-standard network protocols using fibre channels and can be integrated with large variety of applications. In existing system when there is a need to extend the capacity, each server in the architecture must be shut down manually to configure new storage. SAN provides a better way to add storage and avoids interruption associated with server-attached storage enhancements.

SAN effectively acts as a complete storage bus operating the same networking elements of a LAN comprising hubs, switches, bridges, and routers. The storage and servers can de-couple allowing the storage to be placed away from host servers. With this, it provides and ensures the necessary disaster management capability. It carries only storage data and can be shared with multiple servers without having to constrain the available bandwidth as in Local area networks.  Here, data is stored centrally and distributed to host servers on demand. High-performance fibre channel protocols and switches enable storage connections are efficient and reliable. The device connections are based on either SCSI or native fibre channels.

This technology comes with Management software, which configures and monitors SAN components and enables to work all together. Management software also controls movement of data within the SAN substructure. It is also responsible for discovering devices connected to the SAN such as storage devices, hosts, switches and fabric components.

The Key benefits of SAN include scalability of enterprise data backup, extremely enriched reliability and restore operations. It has the ability to add storage seamlessly, improve data backup times, availability and serviceability of transaction-based applications. It facilitates high accessibility and application failover backgrounds that ensure very high ranks of application availability at optimal costs. Improved disaster tolerance provides high Fibre channel functioning at higher distances between host servers and connected devices. Having fibre channel technology optimizes the efficient transfer of block data and streamlines data backups. As a result, network bandwidth customarily used for data backup can be expended instead for more strategic purposes. There are many service providers, which sell these devices  online at affordable prices.
