Abstract
A method and apparatus for managing power sequencing in a data storage system. The turn-on or spin-up sequence for the media drives in an array of media drives is selectively controlled such that the overall rush current is reduced. The individual drive components are characterized to determine a power profile for each such component. A closed-loop process is then used to manage and reduce peak power requirements when starting up or spinning up an array of media drives using the drive profiles. The media drives can also be organized as a plurality of sets of drives, and a power profile for each set of drives is used to manage and reduce peak power requirements.
