Several main data reliability algorithms are described. Encode and decode principles of CRS algorithm used in storage system are analyzed. Principle of realization of data storage middleware based on CRS is presented. Based on CRS and grid technology, a whole structure of a high reliability storage system is proposed. System reliability is proved theoretically. Storage system performance is tested in LAN environment. Results show that the CRS algorithm based storage system not only ensures data storage reliability but possesses high storage performance.
