LinuxONE and Linux on z Systems Capacity and Solution Planning

Project and Program: Linux & VM, Linux

Tags: Proceedings , SHARE Providence 2017 , 2017

Linux on z Systems is very popular among existing IBM Z customers (and some customers new to the platform) for both server consolidation and for providing 'front-end' services for z/OS, z/TPF, and z/VSE customers. However, determining how large a LinuxONE or IBM Z server is required can be quite complex as you can't just map RPEs, rPerfs, or non-Z cores to the number of IBM Z cores (IFLs) required. Similarly, the memory and I/O design of IBM Z servers are very different from non-Z servers. You also have to take into account the hypervisor that will be used (PR/SM, z/VM, or KVM for IBM Z), the Linux distribution (SUSE SLES, Red Hat RHEL, Ubuntu), and whether or not the applications you require will run on a IBM Z server. This presentation will provide guidance on the planning that has to be done to ensure that the right-sized IBM Z server is selected.-Jim Elliott-GlassHouse Systems Inc.
