I don't understand what this means, since I don't know anything about your business or your customers. > Besides, I understand that running zVM > incurs substantial human costs for system administration.

The amount of time and money you spend on having someone manage your z/VM system is likely going to be far less than the amount of time you waste on managing multiple LPARs of Linux systems. (You don't really think you're going to have just _one_ Linux system do you? What about dev, test, model office, QA?) While there is some value in running a very small number of Linux systems in LPARs, you're cutting yourself off from far more value down the road. Once you have Linux running on z/VM, a lot of things become very easy to do, and therefore you find yourself doing more, faster. It gives you tremendous flexibility to try new things with little or no cost, then ditch the ones that don't work to pursue the ones that do. I've been an advocate of running Linux on the mainframe from the first I heard it existed back in early 2000. One of the most interesting things I've heard from someone running it in production was along the lines of this: Once it becomes quick and easy to create and destroy Linux systems, and your application developers (and their managers) really understand this, it unlocks innovation to a degree not seen previously. Things that are too speculative to try with real hardware, because of capital budgets, amortization and depreciation, are almost no-brainers in a virtual environment.
