ABSTRACT:
A method and system for enhancing the efficiency of communication between multiple host computers and a storage system controller via multiple communication channels. After detecting a transmission of a specific message from the storage system controller to a selected host computer, channel data bits corresponding to that particular communication channel are set within preliminary control words which are stored in temporary storage locations. A timer circuit is coupled to the temporary storage locations and periodically resets the channel data bits. A final control word is then calculated by combining the channel data bits from all of the preliminary control words. A control circuit is then utilized to prohibit the retransmission of the specific message from the storage system controller to the selected host computer for a predetermined minimum period of time in response to the state of the channel data bits within the final control word. Communication efficiency is increased by eliminating unnecessary transmissions of a specific message.
