Outrageous if properly configured. But lets look at the obvious question first. Who selected the NIC cards and are they certified for 10g RAC? The reason I ask is the "good" NIC cards have a keep-alive and try to reconnect. This is the worst possible thing to do with RAC. With RAC you want the cheapest dumbest cards you can find because you want a failure to kill the connection instantly. O/S may also be configured with a keep-alive so check that too.

I routinely get sub-second fail-overs with RedHat Linux.
