Performance research of the distributed parallel server system with distributed parallel I/O interface

Distributed parallel is an important research and development field in many years, but the researches and developments are only limited to the inside of the distributed parallel system. The interactions between the server and its outside (such as clients) are performed by only one channel (for instance, a computer). The channel is a bottleneck, limiting the reliability/ availability, speed up ratio, efficiency, frequency band and I/O response speed of the system. The nodes of the distributed parallel server with the distributed parallel I/O interface presented in this paper can directly interact on the clients. The client demands over 80 percent are directly sent to the nodes that they can provide required services, while only few demands need dynamical schedule again. The is a broad band network server. The emphasis of the paper is to compare the performances among the distributed parallel server and single computer server, mirro-image server, two-redundancy computer server and cluster server. The results show that this new server is the best one among these servers. The first version of this server is already researched and developed successfully, it is used, and it will go to market.
