If the servers are running Linux, then the OS cost is the same (except, perhaps, for support fees). Also, isn't it typical that you run a database server, and connect to it rather than have all the servers run a copy of the database... otherwise, how are you getting away with only one DBMS license for a lot of Linux instances? The admin (people) costs are certainly greater, but I am confused as to why the software costs would be.
