Considering that the SAN (Storage Region Network) is 1 large storage box comprising quite a few pieces of hard disks, it requires its personal management process to take care of its operations. Nobody server controls the SAN as its disks are allotted to all servers. Via a central console, the SAN administrator switches from disk to disk as though moving close to all servers' storage disk. As added protection, community customers registered to one server are unable to entry the disks of an additional server.



While in the event one with the disks from the SAN is faulty, according to the RAID technology practiced, the SAN is able to rebuild information from your faulty disk onto a spare disk. Then it truly is just a uncomplicated make a difference of popping out the faulty disk, changing a great one particular into put and formatting it to readiness. If your SAN is put in place well, it plays a significant part in receiving the organization back again onto its feet throughout catastrophe recovery processes. Backup routines about SAN are also additional successful as compared to server by server backup.
