Hardware, Embedded Systems IDC's newest survey of server vendors shows boxes running every kind of operating system -- except Unix -- sold more during the last three months of 2010. Sales of Linux servers rose 29 percent; Windows rose 16.8 percent, but most surprisingly, sales of mainframes shot up 69 percent " the highest growth rate IDC ever found on mainframes.

The original poster of this line is deluded. IBM is the predominate mainframe maker in the world. AND they sell Linux on their mainframes. I know they support Red Hat but you might be able to get Suse also.

It is interesting to speak with sysadmins about the Mainframes running Linux: they say it really sucks. That Linux is unstable and they encounter all sorts of problem.

On top of that, a mainframe is not that fast, cpu wise. Any highend x86 cpu is at least twice as fast. In fact, a better number would be 5x faster. So you need 5 Mainframe cpus to match one high end x86 cpu. This is true, and I can provide links and articles that proves this fact.

MAinframe cpus are good at RAS. That reliability costs a fortune. They are very reliable and tailor made for reliability. But they are not fast.

x86 are very fast, but very unstable and buggy. Every once in a while, intel and AMD has to withdraw x86 cpus because of bugs. Mainframe cpus are not buggy, but they are slow.
