Hi, in my config here I use 2 dual port network cards in each node. I run a 2 node cluster. The nodes are in two racks in the same room. Port 1 of Card 1 and Port 1 of card 2 are bonded to bond0 and are (for fail over and redundancy) connected to 2 Cisco switches. This configuration is save even in the case if on network card will fail. Port 2 of Card 1 and Port 2 of card 2 are bionded to interface bond1. This interface has a private non routed address (192.168....) and is connected to the second with 2 crossed network cables. Therefore I need no switch for the cluster internal traffic. And that means more security because a nonexixting switch can not fail. This configuration works well now for the last two years.
