GDS provides a function that mirrors shared disk units connected a cluster system composed of multiple servers (also referred to as nodes).
This is called shared disk mirroring in distinction from local disk mirroring that mirrors disks connected to a single node.
The GDS's shared disk mirroring function can be used with applications, such as the GFS Shared File System, that provide simultaneous access from multiple servers to shared disks, not to mention switch-over or standby type applications.
