Well, I don't know exactly what you're trying to do, but we've split our iSCSI workload for one of our costumers between two iSCSI targets, with open-e iSCSI server A having half of the storage as source, and the other half as destination. ISCSI Server B has the same setup. Each is replicating to the other. This is sort of a manual load-balancing situation, but it works for us. Apparently, with the new iSCSI failover, it should be possible to automatically switch to the other server automagically in case the other one fails.
