Configuration considerations are described for two-cluster grids. The scenario  that is presented is a typical configuration. Other configurations are possible and might be  better suited for your environment.  Figure G-1 shows a homogeneous TS7740 cluster grid. You can also choose to introduce a  TS7720 only, or a hybrid cluster. For more information about choosing the best configuration  to meet your demands, see 2.5.1, “Homogeneous versus hybrid grid configuration” on  page 100.
