About the cascading failure scenario

In this scenario, another system failure can be tolerated because each system has sufficient Limits to accommodate the service group running on its peer. If MedServer1 fails, its groups can fail over to MedServer2.

If LargeServer1 fails, the failover of the two groups running on it is serialized. The first group lexically, G1, chooses MedServer2 because the server meets the required Limits and has AvailableCapacity value. Group G2 chooses MedServer1 because it is the only remaining system that meets the required Limits.
