A method for enforcing data integrity in an RDMA data storage system includes flushing data write requests to a data storage device before sending an acknowledgment that the data write requests have been executed. The substituted embodiments represent more optimal instruction sequences, reconfigurable logic configurations or combinations thereof which may only be a valid representation of the model being simulated, subject to specific operating conditions. The device provides output in the form of a default output and a number of variants. Test selection, activation, and result output can be implement using a few terminals of the ASIC.
