Distributed Shared I/O System is an important research field of multiprocessor system. HyperTransport is an emerging interconnection standard that offers high-speed, high-performance, point-to-point packet-based link between integrated circuits on a board, particularly between a high-performance processor and peripheral devices. In this paper we introduce a new high-performance distributed shared I/O system developed by ourselves, which uses HyperTransport technology to improve I/O performance and scalability. It attempts to extend the advantages of SMP with the benefits of MPPs and clusters, and overcome the distant I/O problem of distributed non-shared I/O system. To concentrate on a study of the I/O architectural design, some key technologies implemented in the system are discussed.
