Abstract:

Parallel file system is an efficient method of resolving I/O bottleneck in cluster. And the data storage techniques are very important for a parallel file system with high performance and high usability. A simple and efficient parallel file data storage model was implemented. A fixed stripe size and redundant data placement technique was used. Experimental results show the method has improved the usability of file data.

Key words: parallel file system； data storage； usability； fault tolerance
