Tore, Do yourself a huge service. Do not fall into the plot of only focusing on server utilization. Ensure you focus as much if not more effort on software cost.
Staffing, run and maintain and facilities are debatable or not verifiable until some time has past. Software cost improves the value of zLinux and can be factored. Keep it simple. Break it out by application and see if there is a case for strategic direction. My experience in our RFPs has been a surprise. I have been able to make a better business case with high utilized DB servers moving to zlinux then any other service. Why? Software cost and the architecture of System z. Even though there are less instances.

Tore, "z" does lots and lots of little things really well, and is designed to support high resource utilization. Any software or hardware that is used 2% (or even 10%) of the time is a huge cost for underutilized resource. Measuring your "x" servers and showing utilizations is the first step. Any servers that are running applications easily ported to linux on z that are using small amounts of CPU are easy. This is probably 80% of your "x" servers. Pick the low lying fruit (american saying i guess?). If management is convinced by dollars/Euros/Krona savings, then that is the best approach. Come up with a REAL TCO spreadsheet with valid costs that include environmentals, people, software and hardware. If management is more motivated by religion (P vs X vs Z vs Unix), then focus on RAS and Openness of Linux.
