Run Linux workloads on IBM Z and LinuxONE with a cost-effective, dedicated processor
IBM® Integrated Facility for Linux (IFL) is a processor that is dedicated to Linux® workloads on IBM Z® and LinuxONE. It is supported by the Linux operating system for IBM Z and IBM LinuxONE, IBM z/VM® and KVM. IBM z17™ and LinuxONE 5 offer massive processing capacity, on-chip acceleration and industry-leading capabilities for cyber resiliency.
Reduce operational, software, facility and energy expenses with a high Linux server density.
Protect against outages with built-in automated diagnostics, problem determination and isolation.
Create new value with every customer interaction with accelerated AI insights from IBM Z and LinuxONE.
Support up to 208 user-configurable IFLs and up to 64 TB redundant array of independent memory (RAIM). Operate asynchronously with standard processors.
Improve performance capability with enhanced Simultaneous Multi-Threading (SMT) and Single Instruction Multiple Data (SIMD) technologies.
IFLs can be added immediately. IFL technology supports On/Off Capacity on Demand (O/O CoD), capacity upgrade on demand and capacity backup (CBU).
IBM HiperSockets and Shared Memory Communication (SMC) functions provide high-speed communication between logical partitions.
On-chip acceleration provides faster AI insights at scale, increased data transfer rates, lower CPU consumption and rapid encryption of CP Assist for Cryptographic Functions (CPACF).
IFL does not increase charges for IBM Z software running on “standard” processors, nor does it affect the MSU rating or the IBM Z systems model designation.
Manageable by PR/SM or IBM Dynamic Partition Manager in logical partition (LPAR) with dedicated or shared processors, and requires an LPAR definition.
