An S390 mainframe is capable of running many thousand virtual machines and makes a lot of sense for people who either want to stick with the "one service per machine" philosophy, or have applications that shouldn't be sharing memory and disk space for security reasons.

Of course, if you're balking at the $2,500 cost of a VMWare enterprise license, the $500,000 price tag on an S390 will probably kill you. :)
