What is Integrated Facility for Linux?
IBM® Integrated Facility for Linux (IFL) is a processor dedicated to Linux® workloads on IBM Z® and IBM LinuxONE. It is supported by the Linux operating system for IBM Z and LinuxONE, IBM z/VM® and KVM.
IBM z15™ and LinuxONE III offer massive processing capacity, on chip compression acceleration, and a foundation for hybrid cloud computing 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 and LinuxONE III help to reduce the cost of storing, transporting , encrypting and processing data, and can realize storage savings.
