CAREER: Coordinated Power Management in Colocation Data Centers

职业：托管数据中心的协调电源管理该项目的重点是优化托管数据中心的电源管理，为在共享空间中管理自己的服务器的多个租户提供设施支持。作为支持爆炸式信息技术需求的数据中心行业的一个组成部分，多租户托管数据中心在数量和规模上都在大规模扩展。重要的问题是不断增长的运营成本和环境问题。尽管如此，现有的能源效率工作主要集中在所有者运营的数据中心，如谷歌，其运营商对计算资源和设施都有完全和协调的控制，因此它们不适用于托管数据中心，其中各个租户以非协调的方式管理自己的服务器和功耗。因此，托管数据中心在能源效率和可持续性方面远远落后于最先进的业主运营的数据中心，如果不加以解决，这将是数字经济可持续发展的主要障碍。为了实现托管数据中心的能源可持续性，本项目提出了新的基于市场的方法来协调各个租户的电力管理，与优化托管运营商自己的服务器管理和非IT控制（例如，冷却系统）。本项目探讨三个互补的研究重点：（i）全面优化主机代管运营商的设施管理和为租户提供的节能经济激励，以限制碳密集型电力的使用;（ii）实现主机代管数据中心的需求响应，以最大限度地降低主机代管运营商的运营成本，增加可再生能源的采用，并提高电网的可靠性;以及（iii）结合软件模拟、系统原型和实际实施的实验和验证。作为工业界和学术界为实现可持续计算而共同努力的一部分，该项目独特地将电源管理的探索从业主运营的数据中心扩展到多租户托管数据中心。该项目可以促进未来数据中心管理的转变，并改变数字经济的发展方式，产生巨大的经济，环境和社会影响。该项目还包含一个重要的教育组成部分，并提供广泛的机会，吸引不同的学生从事计算机科学。

CAREER: Coordinated Power Management in Colocation Data CentersThis project focuses on optimizing power management in colocation data centers, which provide facility support to multiple tenants that manage their own servers in shared space. As an integral segment of data center industry supporting the exploding information technology demand, multi-tenant colocation data centers have been massively expanding in both number and scale. The significant concerns are both growing operational costs and environmental issues. Nonetheless, the existing energy-efficiency efforts have been dominantly focused on owner-operated data centers, like Google, whose operators have full and coordinated control over both computing resources and facilities, and hence they are not applicable for colocation data centers in which individual tenants manage their own servers and power consumption in a non-coordinated manner. Consequently, colocation data centers are far behind state-of-the-art owner-operated data centers in energy efficiency and sustainability, which, if left unaddressed, is a major hurdle for sustainable growth in digital economy.To achieve energy sustainability in colocation data centers, this project proposes novel market-based approaches to coordinate individual tenants' power management, in concert with optimizing colocation operator's own server management and non-IT control (e.g., cooling system). This project investigates three complementary research thrusts: (i) Holistically optimizing colocation operator's facility management and economic incentives offered to tenants for energy saving, to limit the usage of carbon-intensive electricity; (ii) Enabling colocation data center demand response to minimize colocation operator's operating cost, increase the adoption of renewable energy, and enhance the power grid reliability; and (iii) Experimentation and validation based on combined software simulation, system prototyping, and real-world implementation.As part of the collaborative efforts from both industry and academia to enable sustainable computing, this project uniquely extends the exploration of power management from owner-operated data centers to multi-tenant colocation data centers. This project can catalyze a shift in future data center management and transform the way that the digital economy evolves, bearing great economic, environmental and societal impacts. This project also contains a significant educational component and provides broad opportunities to attract a diverse population of students to engage in computer science.
