项目摘要

A large data center may consume millions of gallons of cooling water each day; in addition, data centers also indirectly consume an enormous amount of water embedded in offsite electricity generation. As a result, water conservation is surfacing as a critical concern for data centers, amid the anticipation of surging water demand worldwide. Left unchecked, the growing water footprint of data centers can pose a severe threat to data center sustainability and may even handicap availability of services, especially for data centers in water-stressed areas. Existing mechanical solutions for conservation, such as using recycled/industry water and directly using outside cold air, are often costly and/or very limited by external factors such as locations, climate conditions, among others. As part of the integral efforts from both industry and academy to enable data center sustainability, this project uniquely integrates water footprint as an essential part of resource management in virtualized data centers. It exploits the inherent yet little-known characteristics of time-varying water efficiency and optimizes resource management for minimizing operational cost as well as water footprint without compromising service quality. To this end, this project investigates three complementary research thrusts: (i) Online computing resource management for water sustainability in the presence of large unknown dynamics (such as highly volatile outside temperature); (ii) Exploration of the dependency of data center water efficiency on cooling systems, and joint optimization of cooling and computing resource management for water sustainability; (iii) Experimentation and validation based on combined system prototyping and software simulation. In addition to its environmental impacts, this project has large societal impacts for its potential to alleviate the growing pressure on data center water footprint effectively and economically. This project will enhance the understanding of interplay among water consumption, power/energy consumption, and resource management in data centers, and lay a solid foundation for sustainable evolvement of greener data centers. New findings and techniques will be readily incorporated into teaching materials. The project also contains a significant component to promote diversity by inspiring minority students, especially Hispanic students, to engage in computer science research.

大型数据中心每天可能会消耗数百万加仑的冷却水。此外，数据中心还间接消耗了大量嵌入在异地发电中的水。结果，在全球范围内的水需求飙升之中，节水浮出水面是数据中心的关键问题。剩下的数据中心的水足迹不断增长，可能会对数据中心的可持续性构成严重威胁，甚至可能残障的服务可用性，尤其是对于水压力区域的数据中心。现有的机械解决方案（例如使用回收/行业水以及直接使用室外冷空气）通常会昂贵和/或受外部因素（例如位置，气候条件等）的限制。作为使数据中心可持续性的行业和学院的整体努力的一部分，该项目独特地将水的足迹作为虚拟化数据中心资源管理的重要组成部分。它利用了时变水效率的固有但鲜为人知的特征，并优化了资源管理，以最大程度地降低运营成本以及不损害服务质量的水量。为此，该项目调查了三个互补的研究推力：（i）在存在大型未知动态（例如高度挥发性的外部温度）的在线计算资源管理，以实现水的可持续性；（ii）探索数据中心水效率对冷却系统的依赖，以及对水可持续性的冷却和计算资源管理的联合优化；（iii）基于组合系统原型和软件仿真的实验和验证。除了其环境影响外，该项目还具有巨大的社会影响，以减轻有效和经济上对数据中心水的压力的潜力。该项目将增强对数据中心水消耗，功耗/能源消耗和资源管理之间相互作用的理解，并为绿色数据中心的可持续发展奠定了坚实的基础。新的发现和技术将很容易纳入教材。该项目还包含一个重要的组成部分，通过激发少数族裔学生，尤其是西班牙裔学生来促进多样性，从而从事计算机科学研究。
