  • 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%

slide47
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.”

Linux and z/VM Technology ExploitationCollaborative Memory Management Assist (CMMA)
  • Extends coordination of memory and paging between Linux and z/VM to the level of individual pages usinga new hardware assist (CMMA)
  • z/VM knows when a Linux application hasreleased a page of memory
  • Host Page-Management Assist (HPMA), in conjunctionwith CMMA, further reducesz/VM processing needed toresolve page faults
  • Can help z/VM host morevirtual servers in the sameamount of memory
  • Supported by System z9and z/VM V5.3
  • Linux support availablewith Novell SLES 10 SP1

Extreme Virtualization with Linux on z/VMLinux Exploitation of z/VM Virtual Disks in Storage (VDISK)
  • VDISK support is Data-in-Memory technology
    • Simulate a disk device using real memory
    • Achieve memory speeds on disk I/O operations
    • VDISKs can be shared among virtual machines
  • Linux exploitation: high-speed swap device
    • Use VDISKs for Linux swap devices instead of real disk volumes
    • Reduces demand on I/O subsystem
    • Helps reduce the performance penalty normally associated with swapping operations
    • An excellent configuration tool that helps clientsminimize the memory footprint required for virtual Linux servers
    • Helps improve the efficiency of sharing real resources among virtual machines
