针对目前存储系统中的DAS、NAS存储方案存在的单点故障与性能瓶颈问题,介绍了一种新型的智能网络磁盘(IntelligentNetwork Disk,IND)存储系统结构,提出了一种面向智能网络磁盘存储系统的文件数据容错算法,理论分析和仿真实验结果表明:多个智能网络磁盘(IND)采用这种容错算法时,其并行数据读取性能良好,已经具备很强的单点容错能力;这表明文中提出的文件数据容错算法能够实现智能网络磁盘之间的容错处理。
To single point fault and performance bottleneck problem in computer storage system,This paper describes a storage architecture of the Intelligent Network Disk(IND),put forward a data fault-tolerance algorithm for this Intelligent Network Disk system.Theory analyze and simulation show that multi-IND storage system has not only good parallel data read/ write performance,but also very nice ability of single point fault-tolerance by this algorithm.It is useful to data fault-tolerance between Intelligent Network Disks.
