If you want to get even more extreme...check out EMC2 SAN solutions.
Clustering servers through a SAN, especially EMC's, would give you
uptime like you wouldn't believe. However, you'll pay for it. The last
installation that served over 9,000 users was over a million dollars I
believe. However, that also came with EMC's huge tape storage unit.
That stuff is unbelievable. =3D20

Like Neil, in a high availability scenario I would say Cluster it. The
trick is that you have to define what an acceptable amount of down time
is for the services. So a out of commission File server that hosts home
dirs, data etc, may have a SLA of 4 hours of down time. (tough to
recover if you loose a mother board and don't have spares, fast backups
etc.) But if is not so important and you can accept a day then so be it.
Or if it is 24x7 type system with requirements for 4 9's I would go with
a cluster or at least replicate the home dirs. Replication can be done
on the cheap if you cant get budget for clustering. I mean replicate the
data to a secondary server, then set the home dirs via login script as
the user logs on. You can put some logic in the script to check for the
primary server and if it failed set the home dir to the secondary
server. This is not perfect of course but gets you to the 4 hour SLA. (I
prefer clustering but not every one has the budget right away)

I put profiles (mandatory) and home directories on MSCS clustered file
shares (same for printers, as it happens).
Not totally flawless, but generally very robust, and quickly resolvable
for most failures.
I might add, the reason for using MSCS, isn't purely for terminal server
environments.
