Abstract
Storage systems configured for improved N-way connectivity among all of a plurality of storage controllers and all of a plurality of storage devices in the system. All controllers of the storage system are coupled through a switched fabric communication medium to all of the storage devices of the storage system. Thus, the back-end interface of each storage controller of the storage system is used for all communications with any of the storage devices as well as for any communications among the controllers to coordinate the N-way distribution of stored data in a declustered RAID storage environment. This use of the back-end channel for all storage controller to storage device N-way connectivity as well as controller to controller N-way connectivity eliminates the need for a dedicated inter-controller interface for such N-way connectivity and eliminates the over-utilization of a front-end (e.g., network) communication path for providing N-way connectivity in the storage system.
