IT-cooling collaborative control methods for battery-aware IT-systems targeting India

Two IT-system control methods, which realize efficient battery usage for battery-powered IT systems targeting developing countries such as India, are proposed. The proposed methods control the IT equipment and cooling power collaboratively on the basis of a forecast of power outage duration. To quantitatively evaluate these methods, power outages in Bangalore, India, were measured. The proposed methods were evaluated by using this measured power outage data. According to the evaluation results, the proposed methods can improve a measure of battery efficiency, namely, IT-used-energy (Qt )/battery-used-energy (Qu ), by 39% compared to that of conventional IT systems.
