部分局点要求数据的安全冗余,提出需要建立多个数据中心,实现数据的灾备及恢复的解决方案。
下面我们根据 3PAR 存储提供的SLD,两地三中心的远程数据复制灾备方案。
接下来我们会在SLD的基础上在线转换为 3DC 的数据复制灾备方案。
配置场景:
System A (主存储) , System B (备存储),System C (第三数据中心存储)
要实现的是 System A <--> System B (RCFC Sync), System B <---> System C ( RCIP Period ) , System A <-- >System C (RCIP Period)

有几个地方需要注意:
1. System A, System B, System C, 需要同步的VV大小必须一致,否则就配置失败;
2. 三地的卷类型可以不一致,也就是A可以是CPVV,B可以是TDVV, C可以是TPVV
3. 在开始同步过程中,A到C状态一直显示 New 状态,一旦同步完成后,状态会自动置为 synced 状态
