Abstract
A system and method of providing direct data access between a non-volatile cache and a set of storage devices in a computing system. A system is disclosed that includes: a processing core embedded in a controller card that controls a non-volatile cache system; and a direct access manager for directing the processing core, wherein the direct access manager includes: a switch configuration system that includes logic to control a switch for either a direct access mode or a CPU access mode, wherein the switch couples each of the storage devices, a local bus, and the non-volatile cache system; a command output system that includes logic to output data transfer commands; and a data transfer system that includes logic to manage the flow of data directly between the non-volatile memory and the set of storage devices; and an arbitrator that arbitrates data traffic flow through the switch.
