【Abstract】 Based on the analysis of I/O node failure,an efficient fault tolerance method called Round-robin Redundant Backup of Subfile is proposed.This method ensures that the parallel file can be accessed when the I/O node is failure.Through this method,the reliability and availability of a parallel file system are improved.更多还原
