| 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. |
