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.

用户依靠计算机来保存有价值的数据，并期望这些数据随时可用和可访问。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）来防止因故障而丢失数据。然而，这些技术会消耗更多的能量来维持额外的硬件或执行额外的软件任务，从而使磁盘保持更长时间的忙碌。这就需要在使用能源管理和提高数据可靠性之间进行权衡——这两者都是指导计算机系统开发未来的关键技术。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。利用一种新颖的度量来捕获能源-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源管理。该项目的结果预计将有助于更好地理解存储系统中能源管理和可靠性改进技术的相互作用，以及平衡可靠性和能源效率的新型节能且可靠的存储系统组织和设计。所开发的机制还将促进大规模节能和可靠系统的进一步研究。此外，该项目采用综合研究和教育方法来培训本科生和研究生研究人员，特别是来自代表性不足群体的研究人员。该培训将灌输关键的系统开发技能，并为设计节能且可靠的计算机系统提供宝贵的学习机会。
