组网及说明

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。


配置步骤

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)


SLD Configuration

Background :

System A: 8440 IP 10.12.180.7

System B: 8400b 10.12.172.229

System C: 8400c IP 10.12.172.203

InformOS : 3.3.1 MU5

配置关键点

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
