Excuse me, are you talking of the old Linux-HA which is often referenced 
as "Heartbeat"?

And what kind of two node cluster do you have? What software packages 
have you set up already?

This is RedHat cluster suite, and it uses a fairly complex cluster 
communication. If your cluster communication and all other communication 
use the same network/nics, you might run into trouble if "other 
communication" uses up your network bandwidth.
