db servers separate hardware

[John W. Sopko Jr.]

We have 3 large db/file server machines, (200GB each), and have
run db/file servers on the same machines for over 5 years without
any issues. The admin guide implies if you have 3 or fewer machines
run them both as a db and file servers:

"A simple file server machine runs only the server processes that store
and deliver AFS files to client machines, monitor process status, and
pick up binaries and configuration files from the cell's binary
distribution and system control machines. 

In general, only cells with more than three server machines need to run
simple file server machines. In cells with three or fewer machines, all
of them are usually database server machines (to benefit from
replicating the administrative databases); "
