I have had good success using a product called NeverFail.  It does
exactly that, duplicating not only the Exchange piece, but also the OS
and other critical applications so that a failure of the primary
triggers a failover to the secondary server.  Check out the literature

Subject: [exchangelist] Exchange Server Redundancy

Hi All,
One of our exchange servers experienced a hardware failure this morning
(excellent start to the week!), and as it was the main mailbox store, it
caused a few hours of downtime for most of our users. To prevent this
from happening again, I'd like to have a certain amount of redundancy. I
understand that in a cluster of exchange servers this is possible as
they effectively act as one logical exchange server. 
Is it possible to achieve the same level of redundancy without setting
up a cluster, by synchronising the mailboxes between the two servers?
Would a cluster be overkill for our two servers and 30 odd users?
As part of an exchange cluster - would it be possible for the server to
take on other tasks as an individual?
If you could offer personal advice, or a recommendation of literature,
that would be excellent.
