  Background 		Abstract In this paper, some problems on storage system architecture of computer network are analyzed, a novel storage system architecture of the Intelligent Network Disk(IND) is presented. The internal read and write control algorithms, the tolerant-fault strategies, and the workload balance algorithms for the IND storage system, are all described in detail. Also a basic experimental system of the IND storage architecture has been constructed. Since each IND of the IND storage system is linked directly to the high LAN, some INDs can form a network cluster of storage system. And, it will provide a virtual huge storage system for users. In addition, as each IND has some intelligence, the IND storage system is a flexible Intelligent Network Storage System.

Background This research is supported by the National Natural Science Foundation of China under grant No.60573145, the Hunan Natural Province Science Foundation under grant No.05JJ30120, and the Guangzhou City Project of Science and Technology under grant No.2007J1-C0401.
This paper is a research report on new computer network storage system. With the rapid development of Internet technology, we are faced with an explosive network information data, so a huge storage system of the network architecture is demanded, in response to the growing information in Internet. As there are still many technology problems in the traditional storage system, such as the storage capacity, the performance, the reliability, the scalability. The NAS(Network Attached Storage) and SAN(Storage Area Network) are two useful storage system architectures to solve those problems. However, the SAN may be an expensive scheme to users; meanwhile, the NAS has a problem named as a "single point fault". Therefore, the research on new storage system architecture is demanded.
In this paper a novel storage system architecture of the Intelligent Network Disk(IND) is introduced, which can be linked directly to a high Local Area Network(LAN). The software and the hardware interface to high LAN, the internal read and write commands, and the tolerant-fault strategies of the IND storage system, are described in detail. Finally, some test results of a basic experimental system of the IND storage architecture and the future research works in the IND storage system are given.
Also, the authors present the Intelligent Network Disk(IND), which is aimed at solving problem for architecture in network storage system. This research has important reference to network storage system architecture research.
In recent years, the work group has focused on the study of new network storage system, and has published more than 30 papers in some important academic journals, the many paper are included in EI, S CI, ISTP and SA.
