It makes sense generally to have a single MGS per site for multiple filesystems, because if clients are mounting more than one filesystem they can only communicate with a single MGS at a time. In some cases there will of course be a need for multiple MGSes in a single site (e.g. secure and open networks), which is fine as long as clients don't try to mount from multiple MGSes at once.
