智能网络磁盘存储系统的容灾研究

为了应对信息时代巨量数据的存储要求，多种网络存储技术和理论先后出现.其中，智能网络磁盘(intelligent network disk, IND)存储系统理论和实现技术是解决当前网络上的海量信息存储问题的一种重要的新技术方法.然而，至今还少有关于这种存储系统数据容灾性的研究.对智能网络磁盘存储系统进行了简单介绍，根据这种存储系统的数据分布特点和现有的容灾技术，提出了在智能网络磁盘存储系统上实现的自免疫容灾恢复算法和后备智能网络磁盘容灾恢复算法；还通过在高速局域网上的相关实验证明了这两个算法的可行性和正确性;实验和理论都证明了后备智能网络磁盘容灾恢复算法比自免疫容灾恢复算法更可靠.研究工作将对今后智能网络磁盘存储系统的容灾研究有较好的理论借鉴意义和实际参考价值，同时也可以让智能网络磁盘存储技术和理论更趋完善.

Disaster Tolerance in Storage System of the Intelligent Network Disk(IND)

Due to the requirement of storing massive data in information age, a lot of new storage theories and technologies are presented. The storage system of the intelligent network disk (IND) will be an important technological method to solve the problem of massive data storage. There are few researches on data disaster tolerance of this kind of storage system so far. After introducing and analyzing the storage system of the intelligent network, and studying the characteristics of data distribution in this storage system and the existing technology about data disaster tolerance, we put forward a self immunity algorithm and a backup IND algorithm of data disaster tolerance in the storage system of IND. Finally, it is proved that these algorithms are correct and well performed by the experiments on high speed local area network. The theories and experiments have also proved that the backup IND algorithm of data disaster tolerance is more reliable than the self immunity algorithm of data disaster tolerance. The study in this paper will be a good reference or source of theory for the researches on disaster tolerance of the storage system of IND in the future, and perfect the theory and technology of IND.
