Reduce operational, software, facility and energy expenses with a very 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 z16 and IBM LinuxONE 4.

Support up to 200 user-configurable IFLs and up to 40 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 on the fly. 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) functionality provide high speed communication between logical partitions.

New on-chip acceleration provides faster AI insights at scale, increased data transfer rates, lower CPU consumption and rapid encryption of CPACF.

IFL does not increase charges for IBM zSystems software running on “standard” processors, nor does it affect the MSU rating or the IBM zSystems model designation.

Available for all models of IBM z16, z15™, z14®, z13®, z13s® and IBM LinuxONE, and supported by the Linux OS for IBM zSystems and IBM LinuxONE, z/VM and KVM.

Manageable by PR/SM or IBM Dynamic Partition Manager in logical partition (LPAR) with dedicated or shared processors. Requires an LPAR definition.

The IBM z15™ and IBM LinuxONE III enterprise platforms support up to 190 user-configurable IFLs and up to 40 TB Redundant Array of Independent Memory (RAIM). IFL delivers the same functionality as a “standard” processor on an IBM Z enterprise platform. It is designed to operate asynchronously with standard processors.

IFL supports enhanced Simultaneous Multi-Threading (SMT) and Single Instruction Multiple Data (SIMD) technologies to improve performance capability. IFL is always a full capacity processor, independent of the capacity of the other processors on the server.

IFLs can be added on the fly, without affecting the business.

As well, IFL technology supports On/Off Capacity on Demand (O/O CoD), Capacity Upgrade on Demand, and Capacity BackUp (CBU) for emergency situations.

IBM Z® HiperSockets™ and Shared Memory Communication (SMC) functionality provide high speed communication between logical partitions. The technologies can be used for communication between Linux images or Linux and the z/OS® and z/VSE® operating system images. Use a shared OSA-Express connection for high speed communication between a Linux image and z/TPF operating system.

z15 and LinuxONE III continue to implement acceleration directly onto the chip. The new IBM Integrated Accelerator for z Enterprise Data Compression (zEDC) can enable the reduction in size and also increase data transfer rates, with reduced CPU consumption. The dedicated cryptographic co-processor on each core provides hardware accelerated encryption of CPACF.

IFL does not increase charges for IBM Z software running on “standard” processors in the server. It does not affect the MSU rating or the IBM Z model designation. z/VM and most IBM Linux middleware products are priced per IFL with an one-time-charge and an annual, optional maintenance charge. Many software vendors have adopted the IBM pricing model for Linux workloads.

IFL is available for all models of z15™, z14®, z13®, z13s®, and LinuxONE. It can be ordered as a hardware feature; the number of features varies by server model/configuration. It is supported by the Linux operating system for IBM Z and LinuxONE, z/VM, and KVM.

IFL is manageable by PR/SM™ or IBM Dynamic Partition Manager in logical partition (LPAR) with dedicated or shared processors. The implementation of IFL requires an LPAR definition, following normal LPAR activation procedures.
