Abstract
A map of storage locations that indicates storage locations associated whose associated I/O transactions are to be processed by firmware running on a storage controller is maintained. The map is communicated to a storage controller driver. The storage controller driver receives a first I/O transaction request. Based on the map, and the storage location to be accessed by the first I/O transaction request, the first I/O transaction request is sent to a storage device without further processing by the firmware running on the storage controller. The storage controller driver receives a second I/O transaction request. Based on the map and the location to be accessed by the second I/O transaction request, the second I/O transaction request is sent for further processing by the firmware running on the storage controller.
