In most larger installations, servers are separated by function. E.g. like this:

1 Controlpanel Server
X Mailservers
X Webservers
X DB Servers
2 DNS servers

Regarding the database servers I prefer in most caeses to have the db servers on the web servers as db connections over a local socket are faster then db connections over a external network, so the setup can be also:

1 Controlpanel Server
X Mailservers
X Web + Database servers
2 DNS servers
