Okay, well, that's what I've read, but felt their had to be something
more substantial that was part of the picture. Now I have a question
related to this which I will send under a new message.

Yeah, I read about that too :)

The AFS Admin Guide and also _Managing AFS_ by Richard Campbell cover
the 'How many servers is optimal?' topic quite well. The answer is
3.

According to those texts I mentioned above, more database servers (past 3)
does not always equal "good". The more database servers you have, the more
places your updates need to be synchronized to, which puts more load on the
synch site, etc...
Having said that, we have 4 :)
