Parallel Sysplex Aggregation

Operational Criteria to be considered 'actively coupled':

The configuration and operating modes described on this website must be the normal mode of operation for this environment.

The images participating in the sysplex and running the selected systems enablement function must account for at least 50% of the total z/OS, z/OS.e, OS/390 and MVS workload on each machine in the Parallel Sysplex. A mainframe can only be in one Parallel Sysplex for aggregation purposes.

z Systems Application Assist Processors (zAAPs) and System z9 Integrated Information Processors (zIIPs) are included as part of the calculation for this 50 percent criterion. Internal Coupling Facility (ICF) engines and Integrated Facility for Linux (IFL) engines are not included as part of the calculation since they are not running z/OS.
