Building Disaster Recovery Serviceguard Solutions Using Metrocluster with Continuous Access for P9000 and XP A.11.00

In Multi-Target configuration, the data enters the configuration on a specific node and then splits
into two directions. One direction is the replication to one site and the other direction is the
replication to the another site. An example for data being replicated in Multi-Target topology when
the application is running at Site1 is shown in Figure 30 (page 95).
