Non-volatile memory (NVM) is a transformative technology that is dramatically changing how data storage systems of thefuture are built. This technology allows an unprecedented combination of performance and persistence into a singledevice. This project will develop a suite of storage caching techniques for this transformative technology along fourcomplementary dimensions.The first two usage dimensions address the selective use of NVM as host-side read caches for persistently stored dataas well as using their persistence properties explicitly by developing fault-tolerant write caching solutions. Thelatter two develop advanced techniques for delivering storage quality of service (QoS) using NVM caches and building cachingalgorithms that are aware of data reduction techniques, such as deduplication and compression, for the NVM layer. Together, these contributions have the potential to transform enterprise data center storage stacks by readily adopting the best properties of current and future NVM technology. The expected performance benefits apply to a broad spectrum of computer systems and applications.Educational activities will include the involvement of undergraduate students and incorporation of the project's research findings into coursework. Planned outreach activities will focus on recruitment of under-represented students from minority groups in computer science for participation in the project. Transition of the new technologies to practice through open source distribution of the Linux operating system and KVM hypervisor code implementing the innovations are successful expectations.

非易失性存储器(NVM)是一项变革性的技术，它正在极大地改变未来数据存储系统的构建方式。这项技术可以将性能和持久性前所未有地结合到一台设备中。该项目将沿着四个互补维度为这一变革性技术开发一套存储缓存技术。前两个使用维度解决了选择性地使用NVM作为持久存储数据的主机端读缓存，以及通过开发容错写缓存解决方案显式使用其持久性属性。后两者开发了使用NVM缓存提供存储服务质量(QoS)的高级技术，并构建了了解NVM层的数据减少技术(如重复数据删除和压缩)的缓存算法。总而言之，这些贡献具有通过轻松采用当前和未来NVM技术的最佳特性来转变企业数据中心存储堆栈的潜力。预期的表现效益将适用于广泛的计算机系统和应用程序。教育活动将包括让本科生参与，并将该项目的研究成果纳入课程。计划的外联活动将侧重于从计算机科学专业的少数群体中招募人数不足的学生参加该项目。通过开放源码分发Linux操作系统和实现创新的KVM管理程序代码将新技术过渡到实践是成功的期望。
