IBM Remote Mirroring

The IBM Remote Mirroring provides storage system-based data replication using either synchronous or asynchronous data transfers. Metro Mirror is designed to maintain a fully synchronized copy at metropolitan distances. Global Mirror is designed to operate asynchronously and helps maintain a copy at much greater distances. Both functions are designed to support VMware Site Recovery Manager to help speed disaster recovery. The remote mirroring feature for the IBM 2072-3N4 control enclosure is required for both the primary and remote machine. This function is licensed to the control enclosure and a single instance of the license covers the entire system. It is required to deploy a HyperSwap configuration.
