Abstract
In accordance with a computer program product, apparatus and a method there is provided a redundant network wherein a host computer operates with a plurality of storage devices by monitoring conditions of the multipath storage network and controlling a storage multipath device driver in conjunction with an associated storage multipath device input/output (I/O) pending queue to increase I/O throughput to a storage device driver, such as a disk device driver, when I/O demand increases, and to decrease I/O throughput to the storage device driver in the event of an I/O error condition.
