  2. Agenda • Introduction • What is Linux? • Support for Linux • Case Studies • Technical benefits and risks • Summary • QAD Offering

  3. What is Linux? • 1985 Professor Andy Tanenbaum wrote a Unix like operating system from scratch, based on System V standards POSIX and IEEE • MINIX for i386 for Intel PC aimed at university computer science research students.

  4. What is Linux? • Linus Torvalds, used MINIX at the university of Helsinki in Computer Science. • Developed Open Source kernel,published under his own license with added features and improvements • Free Software Foundation • 1991 GNU/Linux, GPL(1983) (GNU is Not Unix)

  5. What is Linux? • 2002 agreement: automated handling of code and delegation to contributors/leaders • Team of leaders, many of them employed by tech companies • More than 200 distributions • redhat Enterprise Linux • Novell SUSE Linux Enterprise

  6. Support for Linux • Thousands of professional programmers employed by IBM, Intel, HP • IBM alone has more tha 600 programmers dedicated to Linux Red Hat: 12.3% IBM: 7.6% Novell: 7.6% Intel: 5.3% Independent cons: 2.5% Oracle: 2.4% LinuxFoundation: 1.6% SGI 1.6% • Parallels 1.3% • RenesasTechn: 1.3% • Academia: 1.2% • Fujitsu: 1.1% • MontaVista: 1.1% • MIPS Techn: 1.1% • Analog Devices: 1.0% • HP: 1.0%

  7. Support for Linux • Linux development • There’s a board of directors that helps set the priorities for Linux development • An average of 10,900 lines of code are added with an average of 5,500 lines removed every day in the kernel code. • Code „signoff” identification: Red Hat 36.4% Google 10.5% Novell 8.2% None 6% Intel 6.4% • IBM 5.3% • Linutronix 2.8% • LinuxFoundation 2.7% • Consultant 1.9% • HansenPartnership 1.6%

  8. Support for Linux - hardware • Hardware vendors • DELL, HP, IBM, SUN… • Intel x86 (32 or 64bit), AMD, • Itanium, Power5/6 • Preinstalled Linux software • Enterprise Linux certifications Hardware Compatibility List http://hardware.redhat.com/hcl/ • Virtualization

  9. Support for Linux - software • Progress • from version 8 http://www.progress.com/progress_software/products/docs/bu_sep/pavail.pdf http://www.progress.com/progress_software/products/docs/bu_sep/openedge_10_availability_guide.pdf • Oracle • from version 8 http://www.oracle.com/technology/tech/linux/index.html

  10. Support for Linux @ QAD • Support for Linux started with version eB • Beginning with QAD2007SE release and OE10 we support Linux 64bit • Breakes the boundary of 2GB address space • Can run large databases for large number of users • Platform & Product Availability Guide http://www3.qad.com/production/cguide.nsf/QADAvailabilityGuide

  11. Support for Linux @ QAD • QAD support all* operating systems equally, but there has shown to be a significant cost benefit in transferring to Linux . • *) listed in the QAD Platform & Product Availability Guide • That said every customer has a different budget and corporate standard, so Linux will not be appropriate for everyone • QAD have no benefit from recommending Linux other than as a neutral party to help our customers save money. • No license fee, no special costs except optional technical consulting

  12. Case study 1: eB2SP11 on HP-UX • Cost of doing nothing over 3 years • £51K O/S support plus undisclosed yearly hardware costs increase due to age of server • Total: £51K+ • Cost of new Linux servers including 3 years support on O/S and hardware • £13K • this is a saving of £38K over 3 years

  13. Case study 1: eB2SP11 on HP-UX • Some pros (all direct quotes from customer) • Backup reduced from 1hour to under 2 mins. • MRP from 6 hours to under 20mins in excess of 100,000 items • Crystal reports happen so fast it makes data access so much quicker for our users. • The users were re-running reports twice as they thought they had mis-keyed the criteria they were running that quickly.

  14. Case study 1: eB2SP11 on HP-UX • Some cons • „The only problem is that it doesn't make the the users type any quicker.” • Customer was able to fund other IT projects using already allocated money • Now starting an upgrade to .NETUI on 2009SE with the spare money.

  15. Case study 2: eB on HP-UX • Cost of doing nothing over 3 years • £51K hardware costs plus undisclosed O/S support • Total: £51K+ • Cost of 2 new Linux servers incl. O/S support and hardware • £22K

  16. Case study 2: eB on HP-UX • Some Pros • „The move from HP UX to Dell Linux has saved us approx £17,000 a year in hardware maintenance costs” • „A good example of the differences we have experienced since moving to the Linux box is our MRP run. We used to run this at 1 am in the morning, 6 hours later it would be complete. Running on the Linux OS it now takes just 15 minutes” • „We also bought a DR server and now have our backup online and AI files copied every hour - resilience hugely increased.”

  17. Case study 2: eB on HP-UX • Some cons • default shells may be different under Linux so ensure thorough testing

  18. Technical benefits of migration • High performance • Common x86 hardware with multiple options. • A lot of expertise available in the IT world • many supplemental admin utilities and front-ends • easy creation of test and DR sites for staff practice or experiments • possible migration to virtual machines or clonning

  19. Technical benefits of migration • Native OS for common GPL software • apache tomcat, etc... • Easy connectivity of Linux server with MS Windows based networks • Make use of the newest hardware architectures and technologies

  20. Technical limitations and risks • Failovercluster managers for Linux • not supported by „procluster” tool, own agent scripts • DR serverwith AI and auto „roll-forward” • Oracle Data Server • supported from version OE10 • Certified software and O/S components • avoid installing risky software, HCL check • Not certified kernel changes • admin can rebuild kernel from other sources • don’t experiment on the live box

  21. Case study 3: eB on HP-UX • Cost of doing nothing over 3 years: • £39K O/S support plus yearly hardware costs increase due to age of server • Total: £39K+ • Cost of New HP-UX machine • £25K plus cost of O/S maintenance over 3 years £39K • Total: £64K

  22. Case study 3: eB on HP-UX • Cost of 2 new linux servers including 3 years support on O/S • £19K • this is a saving of between £20K and £45K over 3 years • Already allocated budget used for funding an upgrade to 2008SE with .NetUI

  23. Case study 3: eB on HP-UX • Pros (all direct quotes from the customer) • Backups reduced from 24 minutes for 25GB to 6 minutes for 32GB • Database Creation & Dump/load times reduced by over half compared to HP-UX 11i • MRP / Transaction Posting / and batch jobs run in a fraction of the time

  24. Case study 3: eB on HP-UX • Data conversion was planned at 39 Hrs but took 16 Hrs with Linux (40% of allocated time) • Some cons • Printer setup was not tested properly and some adjustments needed to be made after go-live. Customer does need to test printers and scripts thoroughly.

  25. How can we help You? • QAD Consulting has successfully migrated a number of our customers from their existing hardware and operating systems to a solution running on Enterprise Linux. • The move to the Linux operating system and new hardware has resulted in all of our pilot sites seeing significant cost benefits as well as improved performance from their QAD applications.
