NOTE
A remote replication relationship can be established between the remote DR center and either production
center.
LUNs of two production centers in the same city form pairs and are accessible to application
servers, achieving service load sharing and implementing intra-city DR for data. A remote
replication relationship is established between HyperMetro member LUNs in the production
center (A) or intra-city DR center (B) and LUNs in the remote DR center, implementing
remote DR for data.
Using BCManager eReplication to Implement DR
BCManager eReplication is a DR management software program specially designed for
Huawei typical DR solutions. It provides a visualized and process-based platform for simple
and fast operations and monitoring, with data consistency, snapshot, and remote replication
supported.
Figure 1-14 illustrates how to use BCManager eReplication to deploy a remote replication
task. Deploy the BCManager eReplication host in the DR center and install BCManager
eReplication Server on the host. Install BCManager eReplication Agent on service hosts and
DR hosts in the production center.
