摘要： 传统的网络文件系统难以满足高性能计算系统的I/O 需求，基于对象存储的全局并行文件系统Lustre可以有效地解决传统文件系统在可扩展性、可用性和性能上存在的问题。该文介绍了Lustre文件系统的结构及其优势，对NFS over Lustre 进行了性能测试，并将测试结果与Lustre文件系统、NFS网络文件系统及本地磁盘Ext3文件系统的性能进行了比较分析，给出了性能差异的原因，提出了一种可行的解决方法。

Abstract: Traditional network file system can not meet the demand of high-performance computing systems, but object-based global parallel file system——Lustre can resolve the problems of traditional file systems in scalability, availability, performance. This paper introduces the architecture and advantage of the object-based file system——Lustre. It does the test of NFS over Lustre, and compares its result with Lustre, NFS and Ext3. It points out the reason of the differences and gives a feasible method.
