Enterprise Linux consolidation and optimization on IBM System z
That Linux has come a long way in the past 15 years is undeniable. It began as a system for small Web servers, and now it spans multiple hardware platforms to run enterprise workloads and technical workloads and to support a wide range of new workloads in social media, Web serving, and cloud computing. Linux is running on millions of server units worldwide and generating more than $4 billion in factory revenue in annual server sales. The opportunity exists to consolidate workloads onto more powerful systems, to reduce operational costs, and to improve scalability, availability, and reliability. This paper describes the Linux environment on the IBM System z mainframe -- and the Integrated Facility for Linux (IFL) specialty engines that support Linux -- which is deployed in more than 30% of newly shipping System z servers.
