FreeBSD: Disaster-tolerant fallover(?) Server switching software for FreeBSD / Linux?

This is not specifically a FreeBSD query but it would most
likely be involving FreeBSD systems somewhere in the chain
of things. (and am not sure of the correct terminology here)
For getting a server system (Web, FTP and Rsync) going where there
is a physically separate redundant "fallover" server -
Is there software available that will detect if the primary
server has gone down (or failing) and auto-switch the
secondary server to take over transparently.
I guess this would also involve software on the DNS server as well
to redefine IP addresses and aliases?
Any clues or links to intelligent ways of doing this with FreeBSD/Linux.
(network group here is primarily composed of Linux fans at the moment)
