Abstract
A storage system controller chip includes routing circuitry comprising a host interface for coupling to a host device and an extension interface for coupling to a secondary controller chip. A host controller is coupled to a logical interface of the routing circuitry for receiving a host data access command from the host device via the host interface and logical interface. The routing circuitry transfers the host data access command to the secondary controller chip via the extension interface. The storage system controller chip further includes processor circuitry coupled to the logical interface of the routing circuitry. The processor circuitry receives an indication from the secondary controller chip via the extension interface that execution of the host data access command has been completed by the secondary controller chip and instructs the host controller to notify the host device that execution of the host data access command has been completed.
