Benchmark games - today: Mainframes

IBM announced a new mainframe … the z10. And they did it again, they play with the utilisation trick. But this time , they strech this even farther. Instead of the 30% utilisation assumed for system competing with their pSeries, they assume 10% utilisation for systems for consolidation on a zSeries. Jeff Savit wrote a nice article about this: The Ten Percent Solution. There is only one thing you can consolidate on a z10 mainframe in a resonable manner: z9 mainframes.
