516 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
Figure 11-82 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 11-83. This example is a star topology (A → B, A → C, and A → D).
Figure 11-83   Star topology
Figure 11-83 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.
