Clusters in a protection group must be defined as partners. Protection groups require a partnership that defines the clusters that can host the protection group. A cluster can be defined in more than one protection group, and the cluster can have a different role in each protection group. For example, the primary cluster of one protection group can also be the secondary cluster of another protection group. A partnership can have any number of protection groups.
The following figure illustrates two clusters that are defined in one cluster partnership and two protection groups.

The following figure illustrates three clusters that are defined in two cluster partnerships and two protection groups.
