Yep.... And each one of those servers requires a physical connection to
electrical power; each requires an operating system license; each one
that runs a database requires a DBMS license, etc., etc. Oh, did you
want Test/Development and QA copies too? More $$$$$.
It is also true, assuming you already have a z/Box, that "you can run a
lot of servers on one IFL", with ONE operating system license, ONE DBMS
license, ZERO physical connections to electrical power, etc., etc.
Depending on the application set, the break-even crossover point could
occur at as low as 5 servers (or server images). And for T/D and QA
copies, just copy a few files, share a few others, create "user IDs" and
profiles, and XAUTOLOG them on. No extra $$$$$.
