Abstract

A method and system for more efficient completion of host-initiated FC I/O operations. Rather than returning FCP response frames from an FC port to host memory within an FC node, the FC port determines, from the content of received FCP response frames, whether or not an I/O operation has successfully completed. In the common case that I/O operations successfully complete, successful completion is indicated to the host processor of the FC node via a single bit flag within a completion message queued to a queue within the host memory. In the uncommon case that an I/O operation unsuccessfully completes, the FC port queues the FC response frame received from the target node to a queue within the host memory and a completion message queued to a queue within the host memory with the single bit flag set to indicate that an error has occurred.
