Abstract
An input/output (I/O) request is received that indicates a priority for performing the received I/O request by a storage controller. If a base device is not available to handle the received I/O request, whether the received I/O request is eligible for performance throttling is determined. The received I/O request is transmitted to the storage controller indicating whether the received I/O request is eligible for performance throttling. An alias device is allocated to the base device based on the priority for performing the received I/O request. If the throttling information received from the storage controller for the previous I/O request indicates that a request type of the received I/O request is not being throttled, and it is determined that the received I/O request is a new request, then a control block is representing the base device is flagged, indicating that the received I/O request is eligible for performance throttling.
