2 Linux S/390 Agenda What is Linux? What is the IBM S/390 Linux Development Strategy S/390 Linux Environmental Requirements S/390 Linux Availability Status Additional source of information Linux is a trademark of Linus Torvalds

3 What is Linux? Popular UNIX-like operating system originally developed by Linus Torvalds as a graduate student in 1991 Developed and tested by the Open Source community communicating via Internet Open Source Software distributed under terms of the GNU Public License (GPL) Packaged and distributed by distributors which offer support (SuSE, RedHat, Caldera, Turbo Linux,... ) Linux is a trademark of Linus Torvalds

4 What is Linux?... Rapidly growing market IDC estimates 5-7 million users, not exclusively on Intel systems Server sales 700k units in 1998, nearly a threefold increase over 1997 Netcraft estimates 58% of web servers run open source operating systems IBM supports the Linux platform in response to customer demand IBM provides complete e-business solutions which include hardware, software and support for Linux

5 Why? Customer demand Bring Linux application middleware portfolio to S/390 Leverage Linux capability for rapid application deployment Leverage large number of Linux trained programmers Bring advantages of open source software model to S/390

6 design Runs native, in an LPAR or on VM/ESA Pure Linux, an ASCII environment Exploits IBM S/390 hardware, including IEEE floating point Released to open source in December, 1999 With the release to open source, IBM did not Announce a product Offer any new services Create a Linux distribution Since that time, IBM did Create a new organization for Linux in the Enterprise Systems Group

7 S390 Native, LPAR or VM/ESA guest requirements Processors 9672 G2 - G6 Multiprise 2000 Multiprise MB storage minimum available for S/390 Linux environment VM/ESA Version 2 Release 2 or later Connectivity Access to the Internet to download code and other deliverables Devices DASD support via ECKD driver One 3380 / 3390 / Multiprise internal disk volume required System console function via Hardware Management Console Network support via ESCON CTC or LCS driver (Ethernet or Token Ring) Workstation with CD-ROM for installation (optional)c

8 Strategy S/390 is pursuing Evaluation of Linux marketplace - especially high end servers Using S/390 Linux to complement S/390 operating systems and leverage enterprise data S/390 hardware value for Linux environments Methodologies for distribution, support, services, pricing S/390 is not pursuing A unique version of Linux A Linux personality on another operating system Replacing an existing operating system with

9 Structure Linux - modular and highly portable

10 A brief history November, 1999 IBM makes Statement of Interoperability for S/390 operating systems and Linux on other hardware platforms December, 1999 IBM releases code modifications to open source which enable Linux to run on S/390 hardware IBM begins joint project with customers and internal sites using Customers world wide download from the internet and begin experimenting February 2000 IBM shows at Linux World events in New York and Paris Linus Torvalds mentions significance of S/390 platform in keynote address March June 2000 IBM shows at IBM S/390 e-business Solutions Conferences

11 Interesting facts Marist College web site - over 20,000 hits Over 1,100 downloads of Over 200 unique, identifiable businesses Number of participants in Marist College discussion group quadruples since December release to open source Download sites for established One web site boasts over 400 packages and applications compiled for Early users contributing press articles on Scott Courtney - LinuxToday - "S/390: The Linux Dream Machine" Daisy Whitney - Open Source IT - "Linux on Big Iron"

14 What does Linux bring to S/390? Applications Large selection Rapid deployment Skills Large numbers of highly skilled programmers familiar with Linux Strong interest in colleges and universities Vendor enthusiasm Major ISV / USV efforts for Linux Implementor enthusiasm Emerging interest in large datacenters

15 Why run Linux on a S/390? Reliability The most reliable hardware platform available. Period. Over 35 years of constant improvements Scalability 15 Linux images possible on native hardware Virtually unlimited Linux images possible with VM/ESA recently demonstrated 41,000 active Linux images on single S/390 VM platform Manageability Centralized Linux systems easier to manage / duplicate Use management functions from S/390 operating systems for Linux (e.g. backup, autostart, etc.)

16 Advantage Single application per server Separate/partitioned data bases Complex system management Complex to integrate applications Support for diverse work loads Multiple applications per server Databases shared with integrity Less complex system management Interoperability and integration between applications Appl A Appl B Appl C S/390 Apps LINUX Apps LINUX Apps UNIX Apps LINUX LINUX LINUX S/390

17 Hardware value... Designed to support mixed work loads Multiple Linux systems using Processor Resource System Manager (PR/SM) VM/ESA Ability to scale from small to very large processor configurations Multiple images for consolidation Complete work load isolation Eliminate network latency Enhanced Multiple Image Facility (EMIF) Highly efficient memory management

18 Joint customer project Purpose Obtain customer feedback on Planning, servicing, distributing, installing, operating Goals/Objectives Validate Linux portability to S/390 Validate installation effort on S/390 Validate application portability Validate application development characteristics Validate quality of S/390-unique documentation Evaluate service criteria for Linux on S/390 Monitor Linux / S/390 operational environment Acquire input for S/390 related deliverables White papers, testimonials, application briefs, references
