Abstract: There is disclosed herein techniques for use in energy-efficient certification of data storage systems. In one embodiment, the techniques comprise a method including a number of steps. The method comprises providing instructions to perform operations in connection with a data storage system, wherein the instructions comprise a set of data storage configuration parameters. The method also comprises receiving results in connection with performed operations, wherein the results comprise power consumed and performance of the data storage system. The method further comprises determining an optimum energy efficient data storage configuration based on the results. The optimum energy efficient data storage configuration is dependent on the power consumed and the performance of the data storage system.
