CRI-CI-ADDO-EN: National File System Trace Repository

三十多年来，计算机系统中最慢和最受限制的组件一直是基于磁盘的文件系统。 因此，文件系统一直是计算机系统研究的一个关键领域。 研究文件系统最有用的技术之一是收集、分析和重放详细的活动跟踪。 在过去，痕迹已被用于回顾性分析，并作为模拟和现场实验的工作负载来源。 然而，许多文件系统的研究一直受到阻碍，缺乏公开可用的跟踪数据，往往导致实验使用不充分的数据集。 在许多情况下，这些数据集并没有发布给其他研究人员使用，这使得比较研究变得困难或不可能。在这项工作中，PI正在运营和扩展IOTTA跟踪存储库（以存储网络行业协会的I/O工具，跟踪和分析工作组命名），为全球研究人员提供标准化的高质量数据集。 该存储库在研究界被广泛认为是文件系统和I/O跟踪数据的最可靠来源，并且每年为全球数百个研究项目提供数据集，证明了其价值。该项目涉及定义标准格式，然后创建工具，使其易于使用的痕迹，尽管他们的巨大规模。因为跟踪存储库本质上是一个社区的工作，所以它由一个经验丰富的研究人员组成的顾问小组监督。

For more than three decades, the slowest and most limiting component in computer systems has been the disk-based file system. For that reason, file systems have consistently been a critical area of computer systems research. One of the most useful techniques for studying file systems is to collect, analyze, and replay detailed activity traces. In the past, traces have been used for retrospective analysis and as a source of workloads for both simulation and live experiments. However, many file-system studies have been handicapped by a lack of publicly available trace data, often causing experiments to be performed using inadequate data sets. In many cases, those data sets are not published for use by other researchers, making comparative studies difficult or impossible.In this work, the PIs are operating and expanding IOTTA Trace Repository (after the Storage Networking Industry Association's I/O Tools, Traces, and Analysis Working Group) that makes standardized, high-quality data sets available to researchers worldwide. This repository is widely known in the research community as the most reliable source of file system and I/O trace data, and has proven its worth by providing data sets to hundreds of research projects worldwide each year. The project involves defining standard formats and then creating tools to make it easy to work with traces, despite their immense size. Because the trace repository is inherently a community effort, it is supervised by an advisory panel of experienced researchers.
