## Example 1: Two-cluster grid for HA and DR 

With a two-cluster grid, you can configure the grid for disaster recovery (DR), high availability (HA), or both. 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.
