Abstract:
A method to manage power in a computing device comprising a controller assembly and a storage assembly comprising a plurality of data storage devices, by selecting a processor parameter, establishing a threshold processor parameter value, establishing a threshold over-parameter time interval, selecting a data storage device parameter, and establishing a nominal data storage device parameter value. The method determines an actual processor parameter value. If the actual processor parameter value is less than or equal to the threshold processor parameter value, the method operates each of the plurality of data storage devices using the nominal data storage device parameter value. If the actual processor parameter value is greater than the threshold processor parameter value, then the method determines an actual over-parameter time interval. If the actual processor parameter value is greater than the threshold processor parameter value, and if the actual over-parameter time interval is greater than the threshold over-parameter time interval, then the method operates each of the plurality of data storage devices using a data storage device parameter value less than the nominal data storage device parameter value.
