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。
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.
