Are you assuming multi-port NICs? Sorry if this is a trivial question but I am
an application programmer and lack your background.

Well, since it's 2012 you use a switch instead of a hub. And as I described
earlier you can take two switches and connect systems to both, reducing the
risk of a hardware fault taking everything down. You use the bonding capability
in Linux to make the two NIC ports appear as one logical interface in the OS.
If you are so worried about building a massively resilient system,
you need to pay someone to build it for you. In my experience, a
poorly built 'redundant' environment ends up with more downtime than
a one with multiple single points of failure.
