The growing shift in the IT world to open systems today means the deployment of Microsoft Windows and Linux based systems. In the not too distant past, when mainframes were considered dinosaurs, the shift to open systems meant moving away from proprietary systems towards UNIX systems, which have since become proprietary themselves. This paper focuses on Windows-based technologies, specifically as they apply to scale-up systems for data centers. When a system is scaled up, a number of performance issues arise. These include application, hardware, systems management and availability. These issues are explored in the context of the large, scale-up, 32-processor Unisys ES7000 “Windows mainframe.”

Technology that was once considered the embodiment of the personal computer has emerged as a powerful, scalable, highperformance force in the mainframe market—one that offers levels of familiarity and standardization that are both compelling and cost effective. This paper tracks the effects of CPU commoditization on the evolution of mainframes since their early proprietary days to their current standardization on Microsoft Windows, and presents a hardware and software solution for providing traditional mainframe characteristics that is packaged in a surprisingly non-traditional manner.
