A computer running Linux is not a server. If it's job is to 
route and forward packets, then it is a router. And the fact
that people are pushing the envelope at 10G is because Linux
routers are already known to do a great job at 1G and below.

You can't buy "...having it work -all the time-". The only way
to achieve that is by building in proper redundancy, probably
N+2 or more, and by paying attention to all the deployment and
operational nits that equipment vendors will not do for you.
Companies like Google have demonstrated that this can be very
effective with cheap components failing all the time.

Contracts never force anyone to help you. They only force the
vendor to pay a penalty when they fail to help you. When miracles
are needed, you had better design it into the system yourself, not
rely on a vendor to provide them.

> Risk assessment folks, risk assessment...

If you want to cover your behind, then buy the big brand names and
forget about the consequences. If you want to operate a network service
that functions all the time, then make sure you control and mitigate 
all the risk elements. Don't assume that a big brand name will do it
for you. In particular, big brand names focus their effort on the 
majority customers so if you want to do something a little bit
you will find that the big brand name won't be able to help you until
next year, and that is assuming that their priorities don't shift your
request right off the list.
