Abstract: Parallel I/O is an efficient way to provide high performance for parallel database system based on the shared nothing architecture. It gives us a very high I/O throughput through parallelism disks service and network transport. This paper designs and implements a parallel I/O in parallel database system based on the shared nothing architecture, and discusses some key problems and implementing technology in designing parallel I/O
