We are in the process of replacing our Bordermanager server and I want to
get a server that is built to be a Bordermanager box, not just another

The Bordermanager server is always being blamed for internet speed. I
want to make sure that we have a server that is powerful enough and that
we get the right configuration for it.

Any suggestions (i.e. number of hard drives, configuration of hard drives,
type of NIC, Processor, amount of RAM)?
