hardware for cyrus murder

[Giridhar Raichur]

We are in the process of converting UW Imap to Cyrus Imap. We have about
10K users using about 100K mailboxes. We anticipate the number of users
to increase to 15K.

I looked at http://asg.web.cmu.edu/cyrus/ocnfig.html that describes
Cyrus Configuration for murder hardware. What is not clear to me is the
basis for determining the number of frontend servers and backend
servers. I would appreciate any help or pointers to additional
documentation.

Thanks.
