It's quite simple. What you need is some basic knowledge in heartbeat or any other FMS and in MySQL-Cluster.
which version of mysql cluster you are using? last time i tested with 4.1.15, after disconnecting ethernet cable from one of the two database hosts of the cluster, it took more than one minute before cluster became operational again (now using only one database host). in my opinion, disconnecting ethernet cable from one database host should not cause any interruption of the service. i complained about this on mysql cluster mailing list and they said that this kind of interruption is "normal" for mysql cluster.
