  • System and method for scalable processing of abort commands in a host bus adapter system
    Patent number: 10423333
    Abstract: An HBA or proxy HBA device is configured to use separate Abort Buffer and I/O Buffer in each channel thereby allowing parallel queuing of regular I/O commands and Abort commands. Processing of Abort commands is prioritized such that Abort commands can be processed before all I/O commands received before the abort command are processed. The use of parallel queuing of regular I/O commands and Abort commands is of particular advantage in systems where multiple channels may receive abort commands simultaneously in the situation where the multiple channels share a common communication resource. In a particular embodiment the abort processing logic is implemented in a fiber channel adapter card which includes a proxy host bus adapter device which connects multiple HBAs via fiber channel to a storage area network.
