What is Integrated Facility for Linux?
IBM® Integrated Facility for Linux (IFL) is a processor dedicated to Linux workloads on IBM Z®. It is supported by the Linux operating system for IBM Z, IBM z/VM® with IBM Wave for z/VM, KVM and container technologies.
IBM z15™ offers massive processing capacity, on chip compression acceleration, and a foundation for private cloud and it continues to offer industry-leading capabilities in security and data privacy, and cyber resiliency.
IFLs allow for a very high virtual Linux server density resulting in reduced expenses in the areas of operational efforts, software licensing, energy and floor space.
IFLs have the Central Processor Assist Crypto Function (CPACF) instructions, and protect against outages with built in automated diagnostics, problem determination and isolation.
Gain from on chip compression
IBM z15 helps to reduce the cost of storing, transporting , encrypting and processing data, and can realize storage savings.
