text: 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.
