Abstract
Methods and systems for using one or more solid-state drives (SSDs) as a shared cache memory for a plurality of storage controllers coupled with the SSDs and coupled with a plurality of storage devices through a common switched fabric communication medium. All controllers share access to the SSDs through the switched fabric and thus can assume control for a failed controller by, in part, accessing cached data of the failed controller in the shared SSDs.
