Abstract
A unique system and method for ordering commands to reduce disc access latency while giving preference to pending commands. The method and system involves giving preference to pending commands in a set of priority queues. The method and system involve identifying a pending command and processing other non-pending commands in route to the pending command if performance will not be penalized in doing so. The method and system include a list of command node references referring to a list of sorted command nodes that are to be scheduled for processing.
