Abstract
A switched node is disclosed for use in a switched fabric network. The switched node comprises a disk and a head actuated over the disk. An integrated disk controller within the switched node comprises more than two bi-directional ports for simultaneously transmitting data in multiple directions through the switched fabric network, each port comprising an input port and an output port. The disk controller circuitry further comprises interface circuitry for interfacing with the head, a data buffer for storing data received from the input ports and data received from the head via the interface circuitry, and routing circuitry responsive to header data received from the input ports and header data received from the interface circuitry.
