Abstract
The present invention provides a novel coordinated shared storage architecture that permits the amortization of cost of the spares over any number of the storage systems and enables improvements to a number of storage system operations. The coordinated shared storage architecture comprises a plurality of storage systems disk shelves via a plurality of intermediate network devices, such as hubs. Each storage system includes a storage operating system having a target device driver module. The target device driver module permits the storage system to function as a SCSI target and thereby receive and process commands directed to it from other storage systems.
