1. An apparatus comprising:

  • an access detector to detect an access type of an access to one of a plurality of serial ports interfacing to serial storage devices, the access being intended to one of a plurality of parallel channels interfacing to parallel storage devices via task file registers of the parallel channels;

    a mapping circuit to map the serial ports to the parallel channels; and

    a state machine coupled to the access detector and the mapping circuit to emulate a response from the one of the parallel channels based on the access type and the mapped serial ports.
