17.2. Simple server hardware consolidation
Server hardware consolidation can deliver advantages beyond hardware savings. For example, application servers that run on the mainframe derive advantages from the outstanding Reliability, Availability, and Serviceability (RAS) of the mainframe hardware.
Figure 17-1 illustrates simple consolidation, where discrete servers on multiple machines are mapped to the same number of Linux images on a single mainframe. The z/VM virtualization allows you to run numerous Linux images concurrently.
