    What is a mainframe controller?
    In addition to this pool of primary processors, mainframes have a network of controllers (special microprocessors) that control the system as a whole. These controllers are not visible to the operating system or application programs.

    What are the internal system controls on a mainframe?
    Figure 1, while highly conceptual, shows several of the functions of the internal system controls on current mainframes. The internal controllers are microprocessors but use a much simpler organization and instruction set than zSeries® processors. They are usually known as controllers to avoid confusion with zSeries processors.

    How did IBM change the mainframe?
    IBM stuck with the mainframe, but reinvented it from the inside, infusing it with an entirely new technology core and reducing its price. IBM introduced the concepts of system clustering and data sharing, and announced S/390 Parallel Sysplex, which made high levels of system availability possible.

    Do IBM mainframes have a Central Processor Complex (CPC)?
    Today's IBM® mainframes have a central processor complex (CPC), which may contain several different types of z/Architecture® processors that can be used for slightly different purposes. Mainframe hardware: Multiprocessors It is possible to purchase a current mainframe with a single processor (CP), but this is not a typical system.

    What is a mainframe processor?
    Mainframe hardware: Terminology In the early S/360 days a system had a single processor, which was also known as the central processing unit (CPU). The terms system, processor, and CPU were used interchangeably. However, these terms became confusing when systems became available with more than one processor.
