Inform writes to inform a controller of availability of a plurality of replacement data buffers are optimally batched as a single message. Batching the inform writes lets the controller maintain control of a bus, thereby letting the controller continue with input operations with less interruption, while still allowing for timely replenishment of data buffers that can be made available to the controller. The number of available data buffers to indicate in the single message can be chosen so that the controller need not be starved of data buffers while waiting for a threshold number of available data buffers to be reached.
