  46. 3 year Business Case • Substantial hardware cost savings, especially with System x • Software is a major cost driver especially WebLogic and Oracle costs per engine. System x provides no relief • People costs are significantly reduced Productivity would improve with Linux on System z. System z already has IT process and administration tools to run efficiently Bottom Line: after considerable “what if” analysis, the conclustion for this situation was Solaris is approximately 3-4 times the 3-year cost of zLinux. Planned IT expense of $1.5 million vs $7.4 million…potential savings 79%

  47. Harness the value of a System z9 EC Mainframe’s high utilization and transform your enterprise’s IT costs • Savings driven by: • Consolidation of OTC SW licenses from 22 to 1 • Savings increase as solutions scale up to a 54 way System z • Other likely Savings: • Energy – adding 22 Intel servers consume 6358 watts vs. 0 watts for one incremental IFL* • Space – adding 22 Intel servers requires 5 square feet. Turning on an IFL takes 0 and you can have up to 54 of them (or 789** equivalent Intel servers) with no additional space • People – adding an IFL or multiple IFLs will not likely require more people to manage them Leverage an incremental IFL in a Web Serving environment and potentially reduce costs by up to 58% when compared to a equivalent Opteron based Sun Solution • SW stack includes WebSphere Application Server ND, Linux and zVM • Based on estimated capacity measurements, and 5% server composite utilization for Intel, your actual savings may vary *Microcode upgrade only ** Based on 5% composite Utilization First National Bank of Omaha - Ken Kucera, senior vice president and division head of FNBO Enterprise Technology Services “For every application I had, I needed another one to five servers behind that, for things like development and application and Web serving. And every 20 servers translates to another body to administer them.”

  49. When consolidating Linux on low utilization Intel servers, the System z9 Mainframe’s ability to provide high utilization may help to reduce both power and facility costs Power and Space Consumption In a consolidation, the System z9 EC may provide up to 4 times the same work in the same space and may provide up to 12 times the work for the same power consumption System z10 EC Linux on Intel 30 250 space power 25 200 power 20 150 KW and SQ Feet 15 space 100 10 50 5 0 0 0 10 20 30 40 50 60 22 157 319 465 602 789 Processors Processors The Linux on Intel servers selected in this example are functionally eligible servers considered for consolidation to a System z running at low utilization such that the composite utilization is approximately 5%. The utilization rate assumed for System z10 EC is 90%. This is for illustration only, actual power and space reductions, if any, will vary according to the actual servers selected for consolidation.
