I've done this two ways in the past. Either I'll give each machine an Infiniband network link and a 1000baseT link and use the Infiniband one as the private network for Ceph, or I'll throw an Infiniband card into a PC and run something like Vyatta/VyOS on it and make it a router, so IP traffic can get out of the IB network. Of course, those have both been for test labs. YMMV.
