Today’s businesses tend to generate massive volumes of data which is stored by online applications. But this can put significant pressure on your disk storage system, while your data flow is only as fast as you network connectivity, which means that in order to move more data, you need to scale your networks. Adding disks to your servers may be a solution, however, doing so will only cause problems such as affecting uptime.

A high-speed network that provides multiple servers access to consolidated pools of shared, block-level storage, Storage Area Networks (SAN) has been increasingly used by businesses of all sizes to improve application performance and availability and to enhance their security and data protection capabilities. Through various types of data virtualisation, data is presented from storage devices to a host which render the storage to appear as if it is locally attached.
