By registering all shared disk units connected to the server with GDS, the system administrator will be able to centrally manage all operations on the disk via GDS's operation management interface.
Since disk units managed by GDS are virtualized as logical volumes, there is no need for the application to handle physical disks.
Various disks can be managed centrally, without regard to the physical configuration (single disk, disk array, multi path) and the intended use (switch-over disk for cluster, concurrent shared disk for cluster).
Whether or not to mirror the managed disk can be determined as necessary.
For example, a user may want to manage a disk array with sufficient availability, without carrying out mirroring.
