Hardware, Embedded Systems "Software that for the first time lets users run native copies of the Windows operating systems on a mainframe will be introduced Friday by data center automation vendor Mantissa. The company's z/VOS software is a CMS application that runs on IBM's z/VM and creates a foundation for Intel-based operating systems. Users only need a desktop appliance running Microsoft's Remote Desktop Connection client, which is the same technology used to attach to Windows running on Terminal Server or Citrix-based servers. Users will be able to connect to their virtual and fully functional Windows environments without any knowledge that the operating system and the applications are executing on the mainframe and not the desktop."

Windows by itself needs 2-3GHz and 2GB RAM.


Windows XP by itself can run on a 450 MHz CPU with only 256 MB of RAM, and can run multiple applications, including MS Office XP, with as little as 768 MB of RAM.

Windows Vista requires more CPU and RAM, but not to the extremes that you listed, especially for normal business office work.

Are you trying to say that a mainframe will run great a many Windows instances without problems? I am just curious, and want to know more about this.


But if a 1000MIPS Mainframe CPU == 4GHz x86 CPU according to
http://www.mail-archive.com/linux-390@vm.marist.edu/msg18587.html
and a Mainframe has 16 CPUs, how many windows instances can you run on a mainframe, you guess? I mean of course, simultaneously using MS Office, Powerpoint, Visual Studio, etc. I am not interested in how many Windows instances a Mainframe can boot.
