Abstract: The inlet air temperature of a data center is directly related to the efficiency of the cooling system.If the temperature can be raised without significant negative impacts on the power consumption and lifetime reliability of the IT equipments, the data center cooling can be more efficient and the cost of operation can be reduced.In this work, we analyze the power overhead and reliability loss of a server system by raising its operating temperature.By making changes to the processor implementation, our simulation results show that the total power consumption of data center can be reduced by 10% to 30% with 10 • C to 15 • C increase in inlet air temperature, while achieving the same reliability and performance goals.
