About AutoStart operation

In this configuration, assume that groups probe in the same order they are described, G1 through G8. Group G1 chooses the system with the highest AvailableCapacity value. All systems have the same available capacity, so G1 starts on Server1 because this server is lexically first. Groups G2 through G4 follow on Server2 through Server4.

As the next groups come online, group G5 starts on Server4 because this server has the highest AvailableCapacity value. Group G6 then starts on Server1 with AvailableCapacity of 80. Group G7 comes online on Server3 with AvailableCapacity of 70 and G8 comes online on Server2 with AvailableCapacity of 60.
