IBM z Integrated Information Processor (zIIP) is a dedicated processor designed to operate asynchronously with the general processors in a mainframe to process new workloads; manage containers and hybrid cloud interfaces; facilitate system recovery; and assist with several types of analytics, systems monitoring and other applications.

An IBM® z Integrated Information Processor (zIIP) is a dedicated processor designed to operate asynchronously with the general processors in an IBM Z® system to help improve utilization of computing capacity and control costs.

In IBM System z9 and successor mainframes, the System z Integrated Information Processor (zIIP) is a special purpose processor. It was initially introduced to relieve the general mainframe central processors (CPs) of specific Db2 processing loads, but currently is used to offload other z/OS workloads as described below.

It is important to have a good balance of GCPs and zIIPs for the products that run in your LPAR. While IBM z/OS Connect runs well on zIIPs, applications such as CICS®, IMS, Db2®, and IBM MQ run mainly on GCPs with a small amount of processing eligible for dispatching on zIIPs.

2017年8月18日 · IBM introduced the zIIP (system Z Integrated Information Processor) in 2006. IBM licenses zIIP hardware for a fraction of the corresponding charges for GPs. More importantly to you, zIIP processors are not counted in the basis for software charges, so you can see major savings by shifting workload from GPs to zIIPs.

The zIIP is designed so that a program can work with z/OS to have all or a portion of its Service Request Block (SRB) dispatched work directed to the zIIP to help free up capacity on the general purpose processor which may make it available for use by other workloads running on the server.

In this session, we will explain how you can start making use of the zIIP and which workloads qualify for the zIIP. We will also provide some best practices on how to maximize the usage of the zIIP.

2024年6月21日 · zIIP-eligible CPU consumption that overflows onto general purpose CPs (GCPs) – known as “zIIP crossover” - is a key focal point for software cost savings. However, despite your meticulous efforts, it is possible that zIIP crossover work is …

The zIIP Exploitation Feature (ZEF) is designed to offload CPU time to the System z Integrated Information Processor (zIIP), a special-purpose processor integrated into the System z server platform infrastructure.

2024年9月30日 · The System z Integrated Information Processor (zIIP) is a specialty processor that can be used to relieve the general purpose processors by offloading some Db2 and other z/OS workloads. zIIP processors are typically less expensive to purchase and also run at full speed on sub-capacity CPU models.
