Figure 10-74 shows an example of a multiple system mirroring configuration.

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.
