In this paper, the authors propose a Joint Energy, Thermal and Cooling management technique (JETC) that significantly reduces per server cooling and memory energy costs. Their analysis shows that decoupling the optimization of cooling energy of CPU & memory and the optimization of memory energy leads to suboptimal solutions due to thermal dependencies between CPU and memory and non-linearity in cooling energy. This motivates the user to develop a holistic solution that integrates the energy, thermal and cooling management to maximize energy savings with negligible performance hit.
