## Example 4: Four-cluster grid in three locations 

The setup that is shown in Figure 2-21 shows the configuration after a merge of grids. Before the merge, the grids were only spread across 10 km (6.2 miles). The client’s requirements changed. The client needed a third copy in a data center at a longer distance. 

By merging environments, the client can address the requirements for DR and still use the existing environment.
