I don't believe DRBD can use to different subnets at the same time, although there's nothing stopping each node from being on a different subnet. What you can do is use the bonding driver to make N physical interfaces appear to the system as one interface. The assumption here is that each physical interface on machine A can talk to each interface on machine B. E.G: Node A eth0 - Switch 1 - Node B eth0 || || Node A eth1 - Switch 2 - Node B eth1 With two switches, you'd connect the eth0 interfaces to one switch, eth1 to the other and then connect both switches together (with an etherchannl trunk probably). You'd then configure eth0/1 on each machine to be in a bonded interface (bond0) which you then assign the IP address to that you'll use for DRBD replication. Hope this helps!
