A method is disclosed to provide power to a plurality of data storage
devices disposed in a data storage system. The data storage system
comprises a system controller comprising a data storage device power-up
algorithm and a plurality of data storage devices, where each of the
plurality of data storage devices cannot automatically provide a device
present signal. The method detects the presence of each of the plurality
of data storage devices, and then provides power to each of the detected
data storage devices using the data storage device power-up algorithm.
