Users rely on computers to save valuable data, with the expectation that the data will be available and accessible at any time. Consequently, storage and server systems have to provide stringent reliability guarantees. Many techniques - redundant data copies, multiple servers, and backup hardware - are employed in modern data centers to prevent data loss due to failures. However, these techniques consume more energy either to sustain additional hardware or to perform additional software tasks that keep disks busy longer. This poses trade-offs between using energy management and data reliability improvement - both of which are critical technologies that will direct the future of computer systems development. Thus, this project investigates the combined impact of energy efficiency and data reliability on storage systems. The utilization of a novel metric for capturing the energy-reliability interactions allows for designing optimization techniques that provide integrated reliability and energy management for modern storage systems. The results from this project are expected to lead to a better understanding of the interactions of energy management and reliability improvement techniques in storage systems, and to novel energy-efficient and reliable storage system organizations and designs that balance reliability and energy efficiency. The developed mechanisms will also enable further research in energy efficient and reliable systems at scale. Moreover, the project employs an integrated research and education approach for training both undergraduate and graduate researchers, especially from underrepresented groups. The training will instill critical system development skills and provide valuable learning opportunities in designing energy-efficient and reliable computer systems.

用户依靠计算机来节省有价值的数据，并期望数据可以随时可用。因此，存储和服务器系统必须提供严格的可靠性保证。现代数据中心采用了许多技术 - 冗余数据副本，多个服务器和备份硬件 - 以防止由于故障而导致的数据丢失。但是，这些技术会消耗更多的能量来维持其他硬件，或者执行使磁盘繁忙的其他软件任务。这在使用能源管理和提高数据可靠性之间提出了权衡 - 这两种都是关键技术，它将指导计算机系统开发的未来。因此，该项目研究了能源效率和数据可靠性对存储系统的综合影响。使用新型指标来捕获能源可靠性相互作用，可以设计优化技术，为现代存储系统提供集成的可靠性和能量管理。预计该项目的结果将使人们更好地了解存储系统中能源管理和可靠性改进技术的相互作用，以及新颖的节能和可靠的存储系统组织和设计，这些组织和设计平衡了可靠性和能源效率。开发的机制还将在大规模上对节能和可靠的系统进行进一步的研究。此外，该项目采用综合研究和教育方法来培训本科和研究生研究人员，尤其是来自代表性不足的团体。培训将灌输关键的系统开发技能，并为设计节能和可靠的计算机系统提供宝贵的学习机会。
