My 2 cents worth: the "cheap DASD" doesn't live up to the reliability standards
that IBM demands for z/OS.
I was discussing this with a Storage Manager at a large Canadian Bank.
His biggest complaint was that the same DASD cost more if he used it under z/OS
than the case under LINUX/AIX/UNIX/etc.
What is the difference?
It's the same hardware.
Is there different microcode?
Yes, sometimes
Different features?
Yes, usually. However it it still possible to compare apples to apples -
i.e. "raw" DASD box (almost) without the features.
Other?
Of course! Mainframe is expensive => since you can afford it you can pay
a lot for anything.
