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)

Cheers,

Lachlan.
