Having taught Global Clustering and its predecessor, I would prefer to see WAC have the ability to failover from one IP to another or make multiple connections over 2 or 3 IPs for higher redundancy. Keep in mind that DR is not HA If the WAC loses the connection, you would get notification and can fix the problem or online SGs at the remote site as appropriate.

Only WAC now ensures communication between clusters. But it is not always good. If WAC is broken it is still possible to use heartbeats (through SRDF ping or steward) but there is no other ways of starting service groups on remote cluster. I don't mean Auto failover option between clusters which is not recommended by Symantec, If steward could handle service group information between clusters ..... It could be really a useful thing! Kind regards, Pavel Tsvetkov
