CSR: Medium: Collaborative Research: NVM-enabled Host-side Caches

非易失性存储器（NVM）是一种变革性技术，正在极大地改变未来数据存储系统的构建方式。该技术允许在单个设备中前所未有地结合性能和持久性。这个项目将开发一套存储缓存技术的这种变革性的技术沿沿着fourcomplementary dimensions.first两个使用维度地址的NVM作为主机端读缓存持久存储数据的选择性使用，以及使用其持久性属性明确开发容错写缓存解决方案。后两个开发先进的技术，提供存储服务质量（QoS）使用NVM缓存和构建cachingalgorithms，知道数据减少技术，如重复数据删除和压缩，为NVM层。总之，这些贡献有可能通过轻松采用当前和未来NVM技术的最佳特性来改变企业数据中心存储堆栈。预期的性能效益适用于广泛的计算机系统和应用。教育活动将包括本科生的参与和将项目的研究成果纳入课程。计划开展的外联活动将侧重于征聘少数群体计算机科学专业人数不足的学生参加该项目。通过Linux操作系统和KVM虚拟机管理程序代码的开放源代码分发实现创新，将新技术转化为实践是成功的期望。

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.
