I configured two smart zone controllers to work in a cluster. Was checking out how fast (or slow) it will boot up/start working after power failure. It is suspicious because it takes too long (10-15min) to boot up and start working. Also, two controllers are connected via 100Mbps switch that I am using only for testing.
10-15 minutes is a good time. Mine also takes more 20-25 minutes, for booting. Don't forget updates: they usually take a long time too, 30-40 minutes sometimes longer if something special is changed.
