FUJITSU Software BS2000 DRV

Mirrored data storage on disk storage systems in BS2000

Current version: V3.2

DRV is a system software product enabling BS2000-systems to mirror data. It works transparently for applications. Each write-task executed on two disks. Read-tasks on the contrary are in DRV-operation-mode served by the faster one of the mirrored-disk-pair. So reading is usually faster in DRV-mode.

The DRV concept foresees that in the event of a disk failure, the affected disk can be replaced while the application continues to run uninterrupted with the mirror disk. Maintenance of a device can also be carried out in this way.
