Abstract
A batch of input/output (I/O) requests, directed to multiple physical domains of storage area network disk (SAN disk), are prioritized for processing based on the workload (pressure) of the target physical domains, and further based on the workload of multiple input/output (I/O) paths available for transmission of the I/O data to or from the physical domains. Requests directed to a physical domain with low pressure (relative to other physical domains to which some of the I/O requests are directed) are queued up and sent to the physical domain on an I/O path having a low workload (relative to other available I/O paths). Requests directed to a physical domain under relatively high pressure are queued up and sent to the physical domain on an I/O path having a relatively higher workload.
