Abstract
In one embodiment, a storage system receives a number of input/output (IO) request transactions at the storage system having multiple storage devices. For each of the IO request transactions, the system determines a number of child IO requests required to complete the IO request transaction and tags the IO request transaction and/or 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 associated with each of the IO request transaction. The system dispatches the prioritized child IO requests of the IO request transaction to storage devices, including grouping the associated child IO request to be dispatched together.
