IBM z Integrated Information Processor (zIIP)

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. A zIIP is designed for select data (database), cloud, and transaction (Java) processing workloads.

zIIPs allow users to leverage additional processing power for new applications without affecting their total million service units (MSU) rating or machine model designation. When workload is dispatched onto a zIIP, the processing cycles that are used do not contribute to the MSU count and therefore do not impact software usage charges. This makes adding new applications to the IBM Z platform extremely cost-effective especially compared to competing platforms such as distributed systems or public cloud.

z/OS® is capable of causing certain types of work to be executed, in part, on zIIPs. The type of work eligible for z/OS redirection to zIIPs can be characterized as non-task service request block (SRB) mode, joined in an Enclave of the Workload Manager (WLM) for z/OS.

For more general information, see IBM z Integrated Information Processor (zIIP).

Requesting Information on zIIP

Qualifying ISVs can request a document with additional information on zIIP. This supplemental material describes the IBM proprietary software interfaces that are capable of causing eligible work of an ISV program to be executed, in part, on zIIPs. It also provides information to direct the SRBs in the Enclave to execute, in part, on zIIPs.

In order to receive this document, the ISV must meet certain requirements.
For a list of the requirements, please send an email to zTech@us.ibm.com with:

  1. zIIP Document as the subject
  2. Include in the body:
    • your company name
    • your name
    • your business phone number
    • your business email address

Notes:

  • The interfaces for creating and classifying Enclaves and scheduling SRBs for execution are already available in existing z/OS product documentation.
  • By sending the email you agree that IBM may use your personal information to contact you about the zIIP Document.
