Michael, I see a huge problem and very likely a support issue as well. Basically what he's saying is that the host will have a *single* logical network interface. That *single* interface will need to serve as the private and public interface and that's where Oracle Support may have some major problems. If these blades only support 2 NICs (and you have no opportunities to expand them), then I'd elect to leave the redundancy aside and take a NIC failure as a whole node failure. Since the only other choice is to combine public and private networks over a single logical interface, removing redundancy so you have 2 separate logical/physical interfaces would be a favorable choice.

Just wondering if anyone on the list sees a problem. “Also, since the c class blades have only 2 physical nics, we are going to trunk multiple vlans through the same bonded interface. Makes for a slightly weird setup; you may want to check it out and play with it before this goes live.”
