摘　　要：随着信息技术的快速发展,数据存储已经从传统的单服务器存储模式逐渐发展到以网络磁盘阵列为中心的集群模式。本文基于网络磁盘阵列构建出在共享磁盘阵列方式下双机热备份的实现。由于其数据的独立集中管理和应用服务器冗余,不仅加快了数据传输速度,而且保证了数据存储的可靠性和完整性,从而大大提高了整个存储系统的性能。With the rapid development of the IT, the data-store complying with tradition single-server is replaced by the one of centering on network attached disk array cluster pattern gradually. Owing to network attached disk array, the array carries Active-standby for HA out. Since the independent management of data concentration and the redundancy characteristic, It causes out a series of changes in data processing such as accelerating the speed of data transmission, ensuring that data-store reliability and completeness, improving performance for the entire date-store system greatly.
