Integrated Facility for Linux

From Wikipedia, the free encyclopedia

The Integrated Facility for Linux (IFL) is an IBM mainframe processor dedicated to running the Linux operating system, with or without z/VM. IFLs are one of three types of mainframe processors expressly designed to reduce software costs. (The other types are zAAP and zIIP.) Microcode restricts IFLs to Linux workload.

IBM introduced IFLs on September 29, 2000. At the same time, IBM introduced a special Linux-only VM-like product, called the S/390 Virtual Image Facility for Linux, to cater to IT staff previously unfamiliar with IBM mainframes. IBM soon discovered that z/VM was not too difficult for new IT staff to learn (and worked better), so IBM discontinued S/390 Virtual Image Facility for Linux in April, 2002.

IFLs are available for all IBM mainframes as far back as the G5 series. Fujitsu and Hitachi also offered IFLs on certain models. An IFL is not required to run Linux — Linux runs on general purpose processors (CPs) as well. IFLs simply cost less.
