Abstract
A first I/O transaction request is sent to a storage controller for processing by firmware running on the storage controller. A second I/O transaction request is sent to storage hardware without further processing by the firmware running on the storage controller. Since the firmware did not process the second I/O transaction request, information associated with the second I/O transaction is stored in in a circular buffer accessible to the firmware running on the storage controller. The firmware running on the storage controller reads, from the circular buffer, the information associated with the second I/O transaction that was stored in the circular buffer.
