This project aims to develop control-theoretic modeling techniques, feedback design methodologies, and virtual machine management tools for resource provisioning in enterprise-scale data centers. First, the Linear-Parameter-Varying approach will be applied to characterize the time-varying behavior of traffic and to provide system adaption to dynamical variation of workloads and operating conditions. Then a distributed yet coordinated control architecture will be developed to address time-varying resource bottlenecks across different tiers for multi-tier applications and to cope with the large scale and complexity of modern data centers. In the end, this project will develop virtual machine implementation of the proposed resource management techniques and prototype a virtualized data center to evaluate the performance of the proposed modeling and design algorithms.If successful, the results of this research will make the following contributions to the computer systems scientific-community and industries: 1) performance models of server systems that can cope with dynamically changing workloads with complex nature, and more importantly, a unifying paradigm that allows the combination of control-theoretic approaches with new advances in workload characterization in the computer systems community; and 2) control architecture that can deal with the growing scale and complexity of modern data centers. In addition, the results of this research will be transformable to ready-to-use software and products for data centers through our collaboration with industrial sponsors. In education, the integrated research and education program will teach fundamentals of control theory in nontraditional control domains, outreach for high school students, and promote diversity by engaging women and minorities.

该项目旨在开发控制理论建模技术，反馈设计方法和虚拟机管理工具，用于企业级数据中心的资源配置。首先，线性参数变化的方法将被应用到表征随时间变化的行为的流量，并提供系统适应动态变化的工作负载和操作条件。然后，将开发一个分布式但协调的控制架构，以解决多层应用程序的不同层之间随时间变化的资源瓶颈，并科普现代数据中心的大规模和复杂性。最后，本计画将开发虚拟机实作所提出的资源管理技术，并建立一个虚拟化资料中心原型，以评估所提出的建模与设计演算法的效能。若成功，本研究成果将对电脑系统科学界与产业界做出以下贡献：1）服务器系统的性能模型，其可以科普具有复杂性质的动态变化的工作负载，并且更重要的是，一个统一的范例，允许控制理论方法与计算机系统界工作负载特性的新进展相结合;以及2）可以处理现代数据中心的不断增长的规模和复杂性的控制架构。此外，这项研究的结果将通过我们与行业赞助商的合作转化为数据中心的现成软件和产品。在教育方面，综合研究和教育计划将在非传统控制领域教授控制理论的基础知识，为高中生提供服务，并通过吸引妇女和少数民族来促进多样性。
