YangHELP: A Profiling Tool for Disk I/O and Networked Storage SystemsAbstractThe major goal of this proposed research is to design and implement a hardware environment for low-overhead profiling/optimization, named HELP. HELP is a framework consisting of a hardware embedded system board and a set of easy-to-use APIs to allow system architects to develop their own efficient profiling and optimization tools for storage operations. A HELP board can be directly plugged into a server or storage system to speed up storage operations. Unlike most existing profiling and optimization techniques, our approach minimizes profiling overheads and data skews resulting in more accurate analysis of disk I/O behavior. By offloading profiling/optimization functions from the host, HELP makes it possible to do runtime monitoring, collecting, analyzing, and optimizing disk I/O and data storage operations in a production system. A system architect is able to explore more opportunities than ever in designing tools for profiling and optimization, studying behavior of storage accesses, and inventing new storage architectures using HELP.Successful completion of the proposed research will result in an effective tool that will have great impact on computer architecture research as well as broader IT community. Researchers can benefit greatly from our HELP system in guiding their search for new architectures and new algorithms for data storage. IT industries can also benefit greatly from our tool in making design choices for storage systems and solutions. It will also have significant impact on computer architecture education by facilitating better understanding of detailed system behavior.

一种磁盘I/O和网络存储系统的性能分析工具摘要本研究的主要目标是设计和实现一个用于低开销性能分析/优化的硬件环境，名为Help。Help是一个由硬件嵌入式系统板和一组易于使用的API组成的框架，允许系统架构师为存储操作开发自己的高效分析和优化工具。帮助板可以直接插入服务器或存储系统，以加快存储操作。与大多数现有的性能分析和优化技术不同，我们的方法最大限度地减少了性能分析开销和数据偏差，从而更准确地分析磁盘I/O行为。通过从主机分流性能分析/优化功能，Help使在生产系统中执行运行时监视、收集、分析和优化磁盘I/O和数据存储操作成为可能。系统架构师能够在设计分析和优化工具、研究存储访问行为以及使用HELP发明新的存储体系结构方面探索比以往任何时候都更多的机会。成功完成拟议的研究将产生一个有效的工具，将对计算机体系结构研究以及更广泛的IT社区产生重大影响。研究人员可以从我们的帮助系统中受益匪浅，帮助他们寻找用于数据存储的新架构和新算法。在为存储系统和解决方案做出设计选择方面，IT行业也可以从我们的工具中受益匪浅。它还将通过促进更好地理解详细的系统行为，对计算机体系结构教育产生重大影响。
