分布式文件系统在线性能测试平台研究与实现

An Online Benchmarking Platform for Distributed File Systems

目前由于缺乏针对分布式文件系统的性能测试工具,在很多研究中依然照搬传统的文件系统性能测试工具和方法,很难满足分布式文件系统性能测试的需求(如避免缓存的影响、多客户端并发测试等)。因此,我们研发了一个分布式文件系统在线性能测试平台,此平台通过提供多种大数据量测试负载,有效地避免了系统缓存和系统老化对测试结果的影响,同时支持在线对分布式文件系统执行性能测试,支持多客户端并发测试,并能够对测试结果进行可视化展示和分析。此外,平台也提供了很好的扩展性,满足多种测试需求。

Due to the lack of benchmarking tools for distributed file systems （DFS）, researchers have to use benchmarks that designed for local file systems. However, these benchmarks are hardly suitable to DFS, for example, it cannot avoid the effect of cache and is not suitable doing concurrency tests, etc. According to the characteristics of DFS, we design a benchmarking platform particularly for DFS. This platform can easily solve the problem of cache using large test data. Also it can provides many other functions, such as online benchmarking, request concurrency testing as well as online result analytics and visualization. Moreover, this platform is good at extensibility, thus can meet a variety of future benchmarking requirements.
