Abstract:
1. A port acceleration apparatus for a fibre channel arbitrated loop, the fibre channel arbitrated loop coupling a plurality of disks, the apparatus comprising: at least one fibre channel input configured to receive data from the fibre channel arbitrated loop; at least one fibre channel output configured to send data to the fibre channel arbitrated loop; at least one device input configured to receive data from at least one of the disks; at least one device output configured to send data to the at least one of the disks; at least one controller configured to process at least one fibre channel primitive received on the at least one fibre channel input to generate, based on the at least one fibre channel primitive, a plurality of states comprising an indication of what is routed to the at least one fibre channel output and what is routed to the at least one device output; a first multiplexer configured to route, in accordance with the plurality of states, data from the at least one fibre channel input or a current fill word to the at least one device output; and a second multiplexer configured to route, in accordance with the plurality of states, data from the at least one fibre channel input, data from the at least one device input, or data from an arbitration generator to the at least one fibre channel output.
