Let's see. I have 4 productions servers: DNS, web, mail, and samba; with samba locked up on a private net. Only DNS is current, the rest are work in progress. I just built my test DNS, which will make the rest easier. So MAYBE 8 boxes, with only 4 up 24/7. Not something to throw a server management system at. I do have a real job which I have to work on this afternoon and tonight.

DNS servers should be built with failover in mind. In the very unlikely event that an update would break something, as long as you haven't automated the same change across all of them, it shouldn't affect anything else.
