摘要
远程磁盘镜像作为对关键领域信息系统、关键数据进行保护,防止灾难发生所带来灾难性打击,是保证企业业务连续性和企业发展的持续性的有效方法。各种实现远程磁盘镜像功能的软件和系统存在一些相似性,SRDF作为远程磁盘镜像典型软件系统,通过分析和研究SRDF的组成、SRDF不同工作模式的实现原理,分析和比较其不同工作模式的特点,实现研究和分析远程磁盘镜像系统的工作原理和实现。
Long-distance disks array mirroring is the mainly effectual way to protect the information system and pivotal data of the pivotal field, to prevent the striking when the disaster having happen and insure the continuity of the corporations＇ operation and development. In all the Long-distance disks array mirroring sofb,vare and system there are something alike, and SRDF is a typical software system of the long-distance disks array mirroring system. In order to study and analyse the working theory and realize way of the lone-distance disks array mirroring system, the makeup of SRDF and the realize theory of different working modes were studied, and the characteristic of different working modes was compared.
