1 Linux on System z A Strategic View Jim Elliott Advocate Linux, Open Source, and Virtualization and Manager System z Operating Systems IBM Canada Ltd. 1 International zseries Oracle SIG to IBM Corporation Linux on System z A Strategic View Datacenters planning to adopt Linux have a key architectural choice to make in designing large-scale implementations Is the best approach to running Linux scale-out with rack-optimized servers, to scale-up with large SMP servers using virtualization facilities to run many images on a single server? For many users, Linux on may be the optimal choice Jim will describe how Linux on System z, in combination with z/vm, will provide a robust Linux environment which integrates well with z/os 2 International zseries Oracle SIG to 18 International zseries Oracle SIG 1

3 Open Source Software Software whose source code is published and made available to the public Community develops, debugs, maintains Survival of the fittest peer review Generally high quality, high performance software Superior security on par with other UNIX systems Often built by community Redistribution rights May be a reference implementation of an open specification Examples of Open Source Software: Apache web server Eclipse application development Firefox browser OpenOffice.org productivity suite Oracle Cluster File System file sharing Samba file/print SendMail mail server TCP/IP networking 5 International zseries Oracle SIG to 18 Why is Open Source important? Can be a major source of innovation Innovation can happen anywhere any time Development through open communities leads to potentially broad ideas and creativity Community Approach Internet has changed how enterprises address technical innovation Shapes technical leaders thinking and approach to broad collaboration Good approach to developing emerging standards Popular Open Source projects can become de facto / open standards Wide distribution/deployment Enterprise customers are asking for it Increase choice and flexibility adoption/use of Open Source can reduce time to market 6 International zseries Oracle SIG to 18 International zseries Oracle SIG 3

4 What is Linux? A UNIX-like Operating System that is community developed with the source code being readily available Robust functionality and scalability Solid stability and security Lightweight and modular Operates on virtually any platform server or client Generally acquired on a support subscription basis from Linux Distribution Partner (LDP) Novell and Red Hat dominant in NA 7 International zseries Oracle SIG to 18 Linux capabilities have evolved and expanded Linux is free Better TCO than UNIX Better TCO than Windows Migrate to commodity hardware Use as a bargaining chip Pluck the low hanging fruit Linux is mature Drives innovation Provides choices Enables consolidation Facilitates simplification Reduces IT costs Results in business advantage Linux runs on x86 Works but not enterprise ready Used in non-critical areas Good infrastructure solution Linux runs on multiple architectures Up to 256 way SMP support UNIX-like features and enhancements Proven reliability, availability and stability Used for mission critical applications Runs ERP applications and databases 8 International zseries Oracle SIG to 18 International zseries Oracle SIG 4

7 Take back control of your IT infrastructure A data center in a box not a server farm Central point of management Increased resource utilization Potentially lower cost of operations Less servers Fewer software licenses Fewer resources to manage Less energy, cooling and space Fewer intrusion points Tighter security Fewer points of failure Greater availability 13 International zseries Oracle SIG to 18 Power and cooling Installation heat and power levels are major concerns Heat/Power density 78% Availability 57% Space constraints 39% Technology changes Monitoring Security Justifying expenditures Datacenter consolidations Hardware reliability Sarbanes Oxley Service delivery Staffing/Training 23% 18% 17% 14% 13% 13% 10% 7% 6% Demands are doubling every 4 years Sources: IBM and Liebert Datacom Equipment Power Trends and Cooling Applications, ASHRAE International zseries Oracle SIG to 18 International zseries Oracle SIG 7

8 Datacentre power and cooling in the news Currently, power and cooling costs consume percent of most operational budgets. Left unchecked, the costs related to power and cooling will be more than costs of purchasing the equipment being run. it is only a matter of time before IT and facilities managers are in a situation where they cannot cool the systems they have, and must make difficult decisions on new facilities, or restricting the growth of new business.
