RE: rac network question

Actually, just so's we're all clear, with the VLAN support that the
gentleman described originally, the interfaces will appear separate -
eth0.1 and eth0.2 (note: different than eth0:1 and eth0:2).  The traffic
will be shared, but as long as the bonding works as it should, it just
means that if a card is lost, both the interconnect and the VIP will
fail over to the other link.  IMHO, while this is suboptimal, it should
work fine.

That's what he's done, combined the both so public & private traffic is
combined. I'm assuming it's not supported and as such as this will be a
very high profile, critical database, he'll have to change.

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.
