Because you move your single point of failure back to the cache ethernet
interface. Not a great tragedy if you've got a decent keep-alive from your l4
switch, but you lose all caching. Many of the applicances have dual ethers, but
none (to the best of my knowledge) have implemented a failover. My preference is
also for a load balance between two ethers, with failover on fault detection - but
for the moment I'd be real happy with a simple failover.
Note that this does not apply to the platform-based systems (e.g. Inktomi).
