Reduce licensing costs with IFL
The Integrated Facility for Linux (IFL) is a processor dedicated to Linux workloads on IBM System z servers. The IFL is supported by the z/VM virtualization software and the Linux operating system; it cannot run other IBM operating systems1.
The attractively priced IFL processor enables you to add processing capacity exclusively for Linux workloads: consolidations, re-deployments and new deployments.
The faster speed of the IFL on the new zEnterprise BC12 (zBC12) and zEnterprise EC12 (zEC12) enables you to host more virtual servers per processor core than other server platforms. Combined with the up to 101 user-configurable IFLs on the zEC12 and up to 13 user-configurable IFLs on the zBC12, the total Linux processing capacity has enormously increased with the latest zEnterprise servers.
Improve your IT economics by consolidating, re-deploying existing and deploying new workloads on zEC12 or zBC12 and reduce expenses in the areas of operational efforts, energy, floor space and software license fees.
The IBM Enterprise Linux Server is a dedicated System z Linux server – a Linux-only server, meaning that all processors are IFLs on this server.
The IBM Enterprise Linux Server builds on the robust and reliable virtualization capabilities available with IBM System z servers and z/VM virtualization software to greatly enhance the economic attractiveness of hosting Linux workloads in a single, easy-to-scale, easy-to-mange system. The Enterprise Linux Server includes processor cores, memory, I/O connectivity, and z/VM software with solution pricing that helps accelerate return on investment.
With the virtualization capabilities of the Enterprise Linux Server, your business can consolidate applications and servers, build clusters that can share system resources at extreme levels of utilization, relocate workloads nondisruptively and provide a more flexible and dynamic IT infrastructure that will help you achieve superior levels of service and greater control in managing the growth of your business.
The Enterprise Linux Server provides an ideal platform for enterprise-class IT optimization and cloud computing. The Enterprise Linux Server is available with the new zBC12 and z/VM Version 6 Release 3 virtualization software.
In this example a traditional System z environment with three general purpose processors adds additional workspace and software in an IFL but still reports its System z capacity. Consequently, executing Linux workload on the IFL does not result in any increase in monthly license charges for the IBM operating systems or IBM software running on the general purpose processor.
Traditional System z environment – business as usual
One IFL added
Multiple IFLs and IBM software added
Moreover, your software vendor may be among those software vendors who have adopted this IBM model for the hardware workspace dedicated to Linux. To determine if the vendor software charges for existing System z applications on your System z servers is unaffected by adding the IFL to the server, please contact your software vendor.
The picture below shows an example with many IFLs and different workloads running concurrently on Linux guests with z/VM, native Linux, z/OS and z/VSE, communicating via HiperSockets, on one physical System z server.
* Open source applications such as Apache and Samba included in cost for the Linux distribution.
1 The IFL may also be used for execution of the OpenSolaris™ operating system. Solaris and OpenSolaris are trademarks or registered trademarks of Oracle and/or its affiliates.
2 z/VM V4/V5/V6 is priced per processor.
3 HiperSockets are an internal high speed communication path between logical partitions in the same System z server.
