Abstract

An information processing apparatus communicates with a storage device and includes a serial interface configured to support plural link rates, and a controller. The controller retrieves from the storage device via the serial interface information indicating a relationship between maximum power consumption and power consumption efficiency value for each link rate in a first power throttling mode that gives priority to performance and a second power throttling mode that gives priority to reduction of peak power, the power consumption efficiency value being a value that corresponds to the number of I/Os per watt, select the first or the second power throttling mode based on the retrieved information and a mode specified from one of three modes, and instruct the storage device to limit power consumption based on the selected power throttling mode. The three modes include a first mode that gives priority to performance, a second mode that gives priority to reduction of power consumption, and a third mode that gives priority to reduction of peak power.
