Metro Mirror - IBM
网页Metro Mirror maintains a consistent copy of data between two IBM System Storage® external storage units. Metro Mirror, when used with cluster technology, provides a high availability and disaster recovery solution. Like geographic mirroring, this technology also mirrors data stored in independent disk pools.
Metro Mirror and Global Mirror - IBM
网页Metro Mirror and Global Mirror are two types of remote-copy operations. You can use these functions to set up a relationship between two volumes, where updates made to one volume are mirrored on the other volume. For Metro Mirror and Global Mirror operations, the volumes can be on two different systems (intersystem).

IBM存储设备远程拷贝方案比较 - merryangine - twt企业IT交流平台
网页同步方案 － Metro Mirror 基于IBM存储设备的同步镜像产品。 Metro Mirror要求写操作在主从存储设备上都完成后才执行下一个写操作。 差异: IBM在实施远程拷贝时采用光纤通道协议（Fibre Channel Protocol，FCP）要优于竞争对手。 标准FCP协议中,命令和协议分别传送；而IBM采用的FCP协议是将命令和数据合并后一起传输，这样即使对于远地传输，同步拷贝的影响也很小。 2. 异步方案 － Global Copy Global Copy 采用的是异步写操作，将主磁 …
