Abstract
In one embodiment, a storage system includes a processor, a memory coupled to the processor to store instructions for execution, and an IO tagging module executed by the processor to determine a plurality of child IO requests required to complete a plurality of received IO request transactions and to tag the IO request transaction and/or the associated child IO requests with a tag identifier uniquely identifying the IO request transaction. The system includes an IO scheduler module executed by the processor to prioritize the IO request transactions according to a policy by grouping the child IO requests based on the associated tag identifier. The grouped child IO requests of the IO request transactions are serviced by a plurality of storage devices of the storage system for an optimal performance.
