Abstract:
1. A declustered Redundant Array of Independent Drives (RAID) storage system comprising: a plurality of storage controllers wherein each controller comprises a front-end interface for coupling with a host system and a back-end interface for coupling with a switched fabric communication medium, wherein the plurality of storage controllers collectively provide declustered RAID storage management for data stored on a plurality of storage devices, and wherein the plurality of storage controllers comprises three or more storage controllers; wherein the switched fabric communication medium is coupled with the plurality of storage controllers and is adapted to couple with the plurality of storage devices, wherein each of the plurality of storage controllers is adapted to communicate through its back-end interface with any storage device coupled with the switched fabric communication medium, and wherein each storage controller of the plurality of storage controllers is adapted to communicate all inter-controller communications through its back-end interface with any other storage controller of the plurality of storage controllers through the switched fabric communication medium.
