  1. Have you also been “asked” to cut costs? Here is how you do it…

  2. The problem in General • Economic crisis (again) • Cost cutting exercises (again) • Complexity (still) • New technology • Managers “demand” it, users “need” it • IT not known for their successes

  3. The Problem for Mainframers • Economic crisis (again) • Cost cutting exercises (again) • New technology • Managers “demand” it, users “need” it • IT not known for their successes • Architects.....

  4. The dilemma Any cost cutting exercise should focus on IT, not just on Mainframe...

  5. ZEN and the art of Holistic cost-cutting... Like acupuncture, focusing only on the part that hurts will not solve the problem

  6. ZEN and the art of Holistic cost-cutting... “The face of the enemy frightens me only when I see how much it resembles me” • IT folks can be arrogant, architects can be arrogant, and mainframers, well....

  7. ZEN and the art of Holistic cost-cutting... Know your enemy and know yourself and you can fight a hundred battles without disaster. Sun Tzu

  8. RUNvsCHANGE Why separating the two makes you look smart...

  9. RUN the BusinessCHANGE the Business • RUN is all about: • Doing day-to-day tasks smarter/cheaper / more efficient • CHANGE is about: • Making the mainframe ready to support changes like • Access from Cloud or Mobile apps • Training new people • Being more agile • Showing you can CHANGE buys you management support

  10. So, pick the right battle... • But the question is; what IS the right battle? • Clear ROI • Management Buy In • You have the skills/resources/knowledge • You know what you want to achieve... • But some are obvious.......

  11. The obvious battle I • Problem: “We need to get rid of people!!” • Also read: http://www.mainframezone.com/it-management/the-effective-cio-mainframe-staffing (but that’s a whole other topic...) • Does the workload reduce? (NO) • Do people expect the same QOS? (YES) • Will you get a raise? (NO) • Solution: Automate and/or buy tools

  12. The obvious battle II.... • Problem: “We constantly cross the 4 hour rolling average!!” • Have you tuned applications/systems/databases recently? (NO) • Do you have time to do so? (NO) • Are you just fire fighting and no proactive monitoring? (YES) • Do you know exactly what runs in which partition so you can move stuff around? (NO) • Solution: Buy Performance Management tools

  13. Others are less obvious.... • “Do more with less..”, “Cut costs with 20%!!” • We have to ask ourselves: • What drives our management? • What keeps them awake? • What DO they know, and what do they NOT know? • Where is all the money spend? • How much can we really save? • If you think running Linux on zSeries is a good idea, but have no clue about cost or savings, stop dreaming....

  14. What drives your Management? • Less complexity • Lower cost • Fewer complaints • Easy budgets • No surprises • Flexibility & Agility • The same things that keep them awake.....

  15. What do they know? “When the only tool you have is a hammer, all problems begin to resemble nails” • In normal terminology: • If your management doesn’t understand the Mainframe, he will have a hard time understanding what you can/cannot do… • Or even simpler: • Explain that some problems that look like a nail are actually more like screws, and you happen to have a screwdriver

  16. Where is the money spent? • Efficient cost cutting is not possible unless you exactly understand the real cost of IT • Shaving 10% off an item that only represents 1% of the IT budget may not be the smartest thing to do • A tunnel vision is even more dangerous: • “I can save 10% with MY version of the solution”.. • Maybe another department can do 20% with THEIR version • Management support and buy-in is crucial....

  17. How much can you REALLY save? • IT people tend to be optimists.. • Saving money requires investments (money, people, tools) • Invest in a proper ROI, it makes you look smart(er) • Do NOT use things like “TBD”, “N/A” or “Unknown” • If you do not know, make an assumption based on real numbers • How to use numbers... • Ask people for data • Ask for proof • Ask for more data • Ask others about the validity of the collected data • Then use the data......

  18. Obvious places to look... • SLA’s • Look for breaches and the associated fines • Prevent a breach and you prevent the fine • Depreciation & HW Replacement • Every 4 year, servers are depreciated and replaced • Often, software is just migrated to new HW • Fast, new servers often not optimally used • “Middleware” software runs better on MF... • File- & Print servers • Database servers, transaction servers, Firewalls, WAS servers etc.

  19. Exercise 1, Part I • 4000 physical distributed servers • 1000 High end & 3000 Low end • 25% is depreciated and should be replaced • 250 High end at $ 10,000 • 750 Low end at $ 2,000 • Total Investment of replacement: 2,500,000+1,500,000=4Mln

  20. Exercise 1, Part II • Replacement • 30% stays on physical servers (75*10,000+225*2,000) = 1,200,000 • 30% can be virtualized on with a ratio of 1:4 • Acquisition of 75 $4,000 blades = $300,000 • Another 30% of these (300) can be Virtualized on the mainframe (average 1:4), we could potentially run those on 75 Linux Images on 20 IFL’s (official price per IFL on z196EC = $55,000) = $1,100,000 • + 90% reduced floor space + 70% reduced labour cost • + savings on V-Lan’s, V-Routers, V-Firewalls • TOTAL Savings: 4Mln – 2,6Mln = 1,4Mln for a project covering multiple disciplines • excluding benefits of floor space, power consumption, reduced network components and labour, database licenses etc... • Other reports state that the license costs of an application like Websphere Linux on System z will be 50% compared to Wintel (https://www.mercurymagazines.com/pdf/NOVELL5.pdf )

  21. Exercise 2, Part I • Lower four-hour rolling average MIPS usage • Measure • Use tools to see what is running where and how often • Trend analysis of Applications • Analyze • Utilize zIIP/zAAP? • Move stuff around in LPAR’s • Change /Move/Delay Batch processes • Plan • Pick a top 5 every week • Test • Implement

  22. Examples from real life.. • Lower four-hour rolling average MIPS usage • Do all batch-jobs that run at the time you hit your limits really need to run at that moment? • Don’t laugh, I have seen 5000 jobs starting at 12 o’clock noon. Just because they COULD... • zIIP • Do you have them? Are they utilized? When should you utilize? • New versions of tools (buffers, type of Disk etc.) • Underutilized new functions that could replace multiple processes • Database tuning is like taking care of plants..

  23. Conclusion • There IS room for savings • Often BIG savings • Treat is as a project • Get management buy-in. • You invest before you can harvest... • Ask your vendors • Be street smart, don’t spend the first month on just 1 problem, saving 0,1% CPU. • Pick quick winners; managers are impatient....
