Supported multiple system mirroring topologies
Multiple system mirroring supports various partnership topologies, as shown in the example
in Figure 10-75. This example is a star topology (A → B, A → C, and A → D).
Figure 10-75 Star topology
Figure 10-75 shows four systems in a star topology, with System A at the center. System A
can be a central DR site for the three other locations.
By using a star topology, you can migrate applications by using a process, such as the one
described in the following example:
1. Suspend application at A.
2. Remove the A → B relationship.
