摘要： 随着云存储的广泛应用，分布式文件系统作为云存储的关键，也受到越来越多的关注。本文分别介绍5种主流的开源分布式文件系统的性能特点，并对HDFS在I/O性能方面进行改进，再在系统架构、访问方式、存储方式等方面对几种分布式文件系统进行对比分析，以便选择适合的分布式文件系统。实验结果显示，改进的HDFS在元数据占用内存方面有了很大的提升，数据读取速度也略高于Lustre。
关键词: 分布式文件系统, Lustre, HDFS改进
Abstract: With the extensive application of cloud storage, distributed file system is considered as a key of cloud storage, attracts increasing attention. This paper describes the performance characteristics of 5 kinds of major opensource distributed file system, and I/O performance is improved on HDFS, the system architecture, access methods, storage and other aspects of server distribated file systems are compared in order to select the appropriate distributed file system. Experimental results show, improved HDFS is great improved in high memory usage, and also slightly faster than Lustre in data read.
Key words: distributed file system, Lustre, improved HDFS
