The Research And Design Of The Intelligent Network Disk Storage System Communication Protocol

With the rapid growth of storage needs, the storage technology develops rapidly. The team designed a new type of intelligent network disk (IND) storage system, which considered about the structure of the network and storage. With the especial kernel optimal design, and an independent file system and protocol processing mechanism, IND is differents from the traditional C/S storage mode, and effectively prevent from the single point of failure and transmission bottlenecks. With the low cost, IND and intelligent disk management provide a new storage scheme for SMEs.IND protocol communication is a major issue of IND Storage System. In order to implement the IND communications, the most important work is to resolve the connections between IND and Ethernet and the Design and Implementation of the protocol.The thesis describes the architecture of IND system software and hardware. Then it elaborates on the principles of data access, data storage theory, communication theory and the major features of IND.The thesis discusses the selection of network access options of IND, and then it discusses several issues of which had to be considering while selecting the Embedded System protocol stack. Considering about the specific work environment and the target of IND, It combines the common network communication protocol with embedded technology, with research the basic ideas of the IND/IP protocol which is used to the storage system for the IND. The subject design objectives are considered in the IND/IP protocol based on the TCP/IP protocol, following the traditional norms of protocol stack. The thesis focuses on the protocol stack design of the overall structure, function modules, the process model and design goals of IND/IP. The design of IND/IP is according to the layered model and principle of protocol design. It explores the IND/IP protocol stack design elements and implementation model according to the layered design order of protocol.Finally, the thesis elaborates IND/IP protocol stack model and the implementation process, and provides the realization flow chart of the corresponding function, and data accessing is implemented by API of socket. Application protocol calls the function of these interfaces in order to implenment specific operations of the protocol stack for specific operations. The entire development process is in the environment of Keil uVision3.With the experimental shows, it consults that IND/IP allows users to directly linked IND with the based on the IND/IP protocol stack,, and can achieve more efficient communication, rapid response to user requests for links. As the use of advanced hardware architecture and excellent software design, IND provides a safe, intelligent storage scheme to SMEs.
