摘　　要：数据已经成为当今用户越来越重要的战略资源,随着网络的发展,分布式数据存储已经成为对付各种数据灾难的一种有效手段。基于IP-SAN的异地容灾备份系统充分利用了IP-SAN自有的优势。研究了基于IP-SAN备份系统的关键数据一致性问题,设计了一种基于IP-SAN备份系统数据一致性测试方法,利用可靠的摘要算法以及改进的报文传输方式,有效地提高了数据一致性测试速度,降低了对网络的负载,提高了系统的可靠性与响应速度,实验证明是一种代价相对较低且切实可行的数据一致性检测方案。Data have been an important tactic resource to user nowadays. Along with the development of network, distributed data storage is an efficiency measure to deal with various data disaster. Remote Disaster-tolerant and Backup System based on IP-SAN take full advantage of IP-SAN itself. The data consistency problem in the key technology of spare system based on IP-SAN is researched, a test scheme of data consistency in spare system on the basis of IP-SAN is designed, enhances the speed of data consistency and the payload of network through utilizing reliable digest arithmetic is reduced and message transmit mode is improved, the system reliability and responding pace is advanced. It has been proved an lower cost and feasible test scheme of data consistency in experimentation.
