20090316541 | STORAGE APPARATUS AND ESTIMATING METHOD OF POWER CONSUMPTION FOR STORAGE APPARATUS - Power consumption is calculated in accordance with an operation state of disk devices without using a power meter in a storage system. The power consumption in accordance with the operation state is calculated as follows.
