通过介绍高可用性系统的设计思想和iSCSI协议的基本原理,以节点级VSCU(虚拟存储控制单元)高可用性子系统的设计和实现为研究重点,提出一种利用iSCSI技术构建远程数据容灾系统的结构模型,并给出了其实现方案和实验平台的构建。
Based on the design pattern of high availability system and the theory of iSCSI protocol, author focused on the design and implementation of node-level VSCU HA subsystem, presented a construct of the long-distance data disaster recovery platform, and the implementation approaches were given.
