The mainframe already has multiple levels of built-in hardware redundancy that contribute to its intrinsic high availability. You can configure the hardware so that the software can directly exploit various levels of hardware redundancy, such as the CPUs and channel paths to devices. Using z/VM virtualization, you can create various types of Linux configurations that provide software redundancy to an application. For example, you can configure hot-standby Linux ...
