Abstract
A combination of a host system and data storage system that enables accurate performance testing of the storage subsystem is disclosed. In one embodiment, a driver of a host system receives a command message from a host system application. The command message enables the driver to generate and communicate one or more storage access commands to the data storage system. The driver then receives one or more execution results from the data storage system and determines and communicates the total execution time of the one or more storage access commands to the host system application. When the host system application determines performance of the data storage system the undesirable impact of the communication overhead between the host system application and the driver is minimized. Accordingly, accurate performance measurements of data storage systems are obtained.
