Patent 7983125 was granted and assigned to LSI Corporation on July, 2011 by the United States Patent and Trademark Office.
An apparatus and method for determining the power consumption of one or more disk arrays are described. Power consumption information for various hardware components of the array, especially that for the disk drives since these consume more than 90% of the required power, are stored in a static data table in a database which may be controller firmware. Through inspection of this table and the chosen state of the individual disk drives as directed by a controller, one may determine the power use of the array.
