A 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 processor, the processing cycles 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 extremely cost-effective especially compared to competing platforms such as distributed systems or public cloud.
While zIIPs exploitation for individual workloads may vary, hardware configuration updates to allocate zIIPs are minimal. Additionally, zIIPs usage is transparent to the applications; no changes are needed within the application to run zIIPs eligible work.
