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.

zIIPs enable customers to use the legendary cyber resiliency, elasticity and scalability of IBM Z® without affecting the million service unit (MSU) rating or the machine model designation that often influences software license charges.

IBM® does not generally assess IBM software charges on zIIP capacity, except when using additional general-purpose CP capacity. 

zIIP on IBM z16

Accelerate AI deployments with zIIP support on IBM z16™

To enable AI workloads, the zIIP eligibility list includes Python-based applications that assist clients, especially those working in Python for AI to continue scaling up smoothly.

The 2:1 zIIP to Central Processor (CP) ratio requirement no longer applies to make broader use of the zIIP specialty engine. This change allows clients to scale up workloads that use zIIPs, including IBM z/OS® Container Extensions (the ability to run Linux directly in IBM z/OS).

Python on z/OS is zIIP eligible

Benefits Move to hybrid cloud

Use z/OS Container Extensions, z/OS Connect, Java and Python on zIIPs to achieve faster time to value in hybrid cloud.

Accelerate digital transformation

Deploy new applications written in Java or Python, use XML or utilize RESTful APIs on zIIPs.

Improve system resilience

Add zIIPS to increase the capacity for System Recovery Boost to speed up shutdown, restart and workload catch-up.

Products and services that use zIIP

Refer to the IBM Authorized Use Table or zIIP Exploiter list for IBM software products that can take advantage of IBM zIIPs.

Hybrid cloud

z/OS Container Extensions

Use IBM zIIP engines to support IBM z/OS Container Extensions (zCX), deploy Linux® applications as Docker/OCI containers on IBM z/OS or run Red Hat® OpenShift® on IBM z/OS as part of an IBM z/OS workload.

zCX helps modernize your existing z/OS applications for hybrid clouds. Current and new applications can call native Linux microservices in Docker/OCI containers on IBM Z systems with minimal latency to deliver new, highly responsive capabilities and applications to your clients and users.
