Server consolidation with SUSE Linux Enterprise Server for z Systems and LinuxONE helps you save money and get the most from your mainframes.

Virtualize, consolidate and save with SUSE Linux Enterprise Server for z Systems and LinuxONE. Boost resource utilization and run Windows workloads

Mainframes are essential—and substantial—investments in your business. Underutilized or idle resources, however, can be a drag on your bottom line, unless you assign them additional workloads. At the same time, businesses with large data centers struggle with server sprawl. IT administrators are often tasked with managing multiple systems, thousands of software licenses and hundreds of applications, lowering total cost of ownership (TCO) even more.

Together, SUSE and IBM have found a solution. By running SUSE Linux Enterprise Server on IBM z Systems mainframes, you can virtualize servers, creating several virtual machines that run on a single processor and handle multiple workloads in parallel. By doing so, you reduce or eliminate the need to buy more hardware. Additionally, server virtualization lets you consolidate physical systems, shrinking your data-center footprint and simplifying maintenance for your IT staff.

Now is the time to virtualize

On an IBM z Systems, you can run Linux both in standalone mode on a logical partition or under IBM's unrivaled virtualization technology, z/VM (an operating system hypervisor designed specifically for z Systems). Using z/VM, you can run multiple operating systems such as z/OS and SUSE Linux Enterprise Server in virtual machines on the host mainframe. Today, about 95 percent of Linux deployments on z Systems run under z/VM.

Additionally, z/VM lets you remap and share existing system resources. This means your virtual environment can be fine-tuned (even dynamically) to adapt to existing and changing needs. Capacity (i.e. central processors, input/output devices and network capabilities) can be added on the fly and redirected when needed elsewhere.

Get more from your mainframes with IFLs

Within IBM z Systems, many types of processor units perform specific functions. An Integrated Facility for Linux (IFL) is a specialized IBM processor that handles Linux workloads exclusively and is supported by the z/VM virtualization technology. IFLs let you buy a single software license and share it across many Linux virtual machines. Because you are charged for only one processor license, running Linux workloads on an IFL keeps the costs of software licenses down.

For example, one license for Oracle Database costs thousands of dollars per processor. On the other hand, running Oracle Database on an IFL with SUSE Linux Enterprise Server for z Systems and LinuxONE and z/VM is dramatically less expensive. You simply buy a single-processor license for Oracle Database for use by several virtual Linux servers and just one SUSE Linux Enterprise Server for z Systems and LinuxONE subscription per IFL.

Save even more with multi-IFL pricing

Enterprise data centers pose problems such as server sprawl, increasing power and cooling costs and suboptimal virtual guest-to-host ratios. To help you conquer these challenges, we offer a special IFL subscription model for SUSE Linux Enterprise Server for z Systems and LinuxONE.

Our multi-IFL pricing helps minimize the total costs of ownership and acquisition when you consolidate workloads to run on Linux for z Systems. Our pricing model offers volume discounts for subscriptions of SUSE Linux Enterprise Server for z Systems and LinuxONE for multiple IFLs. Multi-IFL pricing is available for IFLs running on all types of IBM z Systems hardware.
