What is the IFL processor?

The Integrated Facility for Linux (IFL) is a processor dedicated to Linux workloads on IBM z Systems and expressly designed to reduce costs. It is supported by the Linux operating system, z/VM + IBM Wave for z/VM and KVM virtualization technology.

The latest IBM z Systems mainframes offer massive processing capacity with up to 141 user-configurable IFLs on one server.

Thanks to the economics of running Linux on the IFL mainframe processors, the cost of hosting our document repository is now a third of what it was before, a significant saving.
