I'm assuming you want an LVS'ed firewall with HA in orswe to handle
the situation where 1 NIC goes down on a host, but otherwise
the host (and the other NICs on it) are still functional.
The chances of this happening I would expect small.
Current computer hardware is reliable now and the items
that fail the most are disks with moving parts. Even
these are reliable nowadays, all failing near the end
of their warantee period. I suggest changing out 3yr
disks after 2yrs.
The main use of HA is not for hardware failure but
to allow planned maintenance without interruption to service.
You will get more network interruptions than hardware failures
until you reach a cluster with several 100nodes.
