At prevailing rates per kw, you can figure on $600 per year per 1000 watts. A blade server rack with 5 shelves approaches 20000 watts ($12,000), and a z990 with a single books costs 36000 ($21,600). One z990 costs less that 2 blade racks, and you can probably run z/OS on it at the same time you're running your z/VM. You also need 10 * 208 volt 30 amp power cords for a single 5 shelf rack, and you only need 2 60 amp cords for the z990.
