No one server controls the SAN as its disks are allocated to all servers. By means of a central console, the SAN administrator switches from disk to disk as though shifting around all servers' storage disk. As added protection, regional users registered to a single server can not accessibility the disks of another server.



In the event one particular with the disks inside the SAN is faulty, based on the RAID know-how practiced, the SAN is able to rebuild data in the faulty disk onto a spare disk. Then it truly is just a simple make a difference of popping out the faulty disk, changing a superb 1 into place and formatting it to readiness. If the SAN is set up properly, it plays an important function in acquiring the organization back onto its feet throughout disaster recovery processes. Backup routines more than SAN will also be far more successful when compared with server by server backup.
