【摘要】 当前绝大多数网络存储系统都是通过高速网络进行连接的。论文设计并构建了基于低速WAN的网络软RAID系统(NSRAID),研究了广域网环境下影响网络存储系统性能的主要因素。同时,以网络负载的角度分析了远程存储节点数、网络存储协议和数据布局方式影响系统性能的内在原因。在此基础上,针对广域网不同的网络性能提出了提高网络软RAID系统性能的方法。更多还原

【Abstract】 Currently ,most network storage system are connected by high speed network.The Network Software RAID system(NSRAID)based on low speed WAN is designed and established in this paper,and the major factors which influence the network storage system’s performance are researched under WAN.At the same time,this paper analysis the causes of which the number of remote storage nodes,the protocol of network storage and data Layout mode influence system performance in direction of network load.Based on the analysis,the method for improving the performance of network software RAID is presented under differently WAN’s performance.更多还原
