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 z16™ and LinuxONE 4 offer massive processing capacity, on-chip acceleration and industry-leading capabilities for cyber resiliency.

Features

• **Extensive processing capacity: **Support up to 200 user-configurable IFLs and up to 40 TB Redundant Array of Independent Memory (RAIM). Operate asynchronously with standard processors.
• **Designed for performance: **Improve performance capability with enhanced Simultaneous Multi-Threading (SMT) and Single Instruction Multiple Data (SIMD) technologies.
• **Flexibility to add IFLs: **IFLs can be added immediately. IFL technology supports On/Off Capacity on Demand (O/O CoD), Capacity Upgrade on Demand and Capacity BackUp (CBU).
• **High-speed communication: **IBM HiperSockets and Shared Memory Communication (SMC) functionality provide high-speed communication between logical partitions.
• **On-chip acceleration: **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).
• **No effect to MSU rating: **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.
• **Widely available and supported: **Available for all models of IBM z16, z15®, z14®, z13®, z13s® and IBM LinuxONE, and supported by the Linux OS for IBM Z and IBM LinuxONE, z/VM and KVM.
• **Flexible partition management: **Manageable by PR/SM or IBM Dynamic Partition Manager in logical partition (LPAR) with dedicated or shared processors. Requires an LPAR definition.

Benefits

• **Lower expenses: **Reduce operational, software, facility and energy expenses with a very high Linux server density.
• **Reduce risk: **Protect against outages with built-in automated diagnostics, problem determination and isolation.
• **Accelerate AI: **Create new value with every customer interaction with accelerated AI insights from IBM z16 and LinuxONE 4.
