Toward Efficient and Green Power Management for Internet Data Centers

今天的互联网数据中心（IDC）在通信和计算能力方面取得了重大进展。近年来，随着互联网服务需求的急剧增长，互联网数据中心（IDC）所使用的能源也在飙升。如何对互联网数据中心进行高效、绿色的电源管理，正成为包括政府机构、金融机构、医院以及大型IT公司在内的数据中心运营商所面临的首要问题。在这个项目中，我们将研究这个重要而具有挑战性的问题。 具体而言，我们将研究三个主题：（A）集成微观级节能设计和宏观级资源管理服务的整体电源管理;（B）数据中心和智能电网的智能交互和协调;（C）由可再生风能供电的数据中心。我们将提出新的整合架构、新颖的模型与分析技术，以及适应性的策略与演算法，以支援IDCS的有效与绿色电源管理。我们将借鉴多个学科的理论和技术进步，包括节能设计、容量规划、经济建模、优化和控制以及分布式处理，以设计智能策略来实现高效的电源管理。 这项研究的潜在影响可以总结如下。首先，我们将提供一个全面的工程框架及其相关的分析基础，为高效和绿色电源管理的IDC。该项目的研究成果可能会产生巨大的经济和环境影响，因为它大大降低了能源消耗。第二，通过科学期刊的出版物和互联网上的成果传播，我们将把我们的研究经验和成果提供给广泛的科学界，以刺激数据中心电源管理的新应用和创造性发现。最后，我们还致力于将前沿研究与教学和推广计划相结合，为学生提供实践经验。

Today's internet data centers (IDCs) are achieving significant advances in communication and computation capabilities. As the demand on Internet services drastically increases in recent years, the energy used by Internet data centers (IDCs) has been skyrocketing. How to conduct efficient and green power management for Internet data centers is becoming a top concern faced by data center operators including government organizations, financial firms, hospitals, as well as major IT companies. In this project, we will investigate this important and challenging problem. Specifically, we will study three topics: (A) Holistic power management integrating micro-level power-efficient designs and macro-level resource management services; (B) Intelligent interaction and coordination of data centers and smart grids; (C) Data center powered up by renewable wind energy. We will propose new integrated framework, novel models and analysis techniques, and adaptive strategies and algorithms to support the efficient and green power management for IDCS. We will draw upon theories and technical advances in several disciplines including power-efficient designs, capacity planning, economic modeling, optimization and control, and distributed processing to design intelligent strategies to carry out efficient power management. Potential impacts of this research can be summarized as follows. First, we will provide a comprehensive engineering framework and its associated analytic foundations for the efficient and green power management of IDCs. Research findings from this project could have great economic and environmental impacts due to the significantly reduced energy consumptions. Second, by publications through scientific journals and dissemination of results on the Internet, we will make our research experiences and results available to a broad scientific community, to stimulate new applications and creative discoveries in data center power management. Finally, we are also committed to integrating cutting-edge research with teaching and outreach programs, giving hands-on experiences to the students.
