IBM Mainframe or HP Superdome

[Delrish]

Hello All,

Does anybody have any information about the amount of different model of HP Superdome’s MIPS (Million Instructions Per Second)?
Do you think Superdome is a replacement for IBM Mainframe?
Which one do you prefer and why?

Alireza,

IMHO you're comparing apples and oranges. UNIX and mainframes do completely different types of processing very well.

Mainframe I/O is far superior to UNIX I/O and was built for batch processing. UNIX batch processing is not very good. On the other hand, UNIX was built for fast interactive multiuser, multitasking processing and handles that much better than mainframes. Mainframe security is better than what UNIX provides. However, neither replaces the other. It depends on what you want to use them for.

I hope that helps.
