Abstract
In one embodiment, a storage system receives a number of input/output (IO) request transactions at the storage system having multiple storage devices, the IO request transactions including at least a read and a write. For each of the IO request transactions, the system determines a number of child IO requests required to complete the IO request transaction, where the child IO requests includes a write child IO request and a read child IO request. The system tags the associated child IO requests with a tag identifier uniquely identifying the IO request transaction within the same session. The system prioritizes the IO request transactions based on a service priority level and completeness of each of the IO request transactions dynamically determined at a point in time and services the child IO requests according to a prioritized order to reduce a time to complete the IO request transaction.
