摘　　要：在数据存储研究中,提高存储系统的性能和可用性是一个普遍关心的话题。iSCSI存储系统具有容量大、高性能、扩展性好等优点,但仍然不能克服目前磁盘I/O速度普遍跟不上处理器的速度和网络传输速度的问题。为了克服这个缺点,本文提出了一种在网络存储集群的不同服务器内存中创建虚拟磁盘的方法,来减少写延时。实验结果证明该方案能有效地提高网络存储系统的性能。In data storage research, what is concerned is to improve the performance and usability of storage system, iSCSI storage system has such advantages as great capacity, high performance and expansibility, but it can not make I/O speed match the speed of the processor and network transmission speed. To overcome this problem, the author brings forward a scheme that a virtual disk is created in different server memories of network storage clusters to reduce write delay. According to experimental results, it is showed that this method can effectively improve the nerformance of network storage svstem.
