This document provides information on Entire Net-Work for zIIP, a selectable unit of Entire Net-Work that enables Entire Net-Work to make use of IBM’s zIIP engine. Entire Net-Work for zIIP enables Entire Net-Work on z/OS to offload part of its workload from the mainframe’s general processors (GP) to System z Integrated Information Processors (zIIP).
Offloading work from the GPs will free up some of their capacity. This helps decrease the total cost of operation (TCO) of the GPs and makes room for running additional workload on them. Furthermore, the use of Entire Net-Work for zIIP may result in performance benefits by increasing the throughput for certain workloads.
Entire Net-Work for zIIP supports the following Drivers:
This documentation is organized under the following headings:
