IBM's System z Integrated Information Processor (zIIP) is a specialty offload engine that helps improve computing performance for a subset of mainframe workloads.
IBM designed zIIP to optimize computing resource utilization and improve performance for several types of data and transaction processing workloads including business intelligence, enterprise resource planning and customer relationship management, and select network encryption workloads.
The zIIP processor is available on all IBM System z9, System z10 and zEnterprise servers (System z).
Work from suitable tasks running in IBM's z/OS mainframe operating system isallowed to access the zIIP's execution environment rather than using the main or general-purpose processor.
The mainframe's transactional data stores and applications that run on distributed servers can work together. On zIIP, workloads connect, manage, spread and secure the data and transactions derived from the mainframe.
IBM has two other specialty engines: IFL and zAAP. The IFL is a processor that runs Linux workloads on IBM System z servers and can increase processing capacity. The zAAP processor allows Web-based applications and service-oriented architecture-based technologies to run. The zAAP-eligible workloads may also run on zIIP; the combination of the specialty engines is cost-effective and simplifies processes.
