Why Are There Specialty Engines?

  • Out of Capacity

    • Traditionally, You Would Upgrade the Machine With General Purpose Engines (GPs)

      • New Capacity That Will Be Included in the Announced MSU Value

      • Adding GPs May Involve Upgrade Fees for “Capacity Based Licenses” (IBM and ISVs)

      • New Capacity May Lead to Higher Simultaneous 4HRAs, Leading to Higher Monthly Charges for Variable WLC Products (IBM and ISVs)

  • If You Have Eligible Work That Could Move to zXXP . . .

...

  • Same Installed GP MSU Capacity

  • Eligible Work Moved to zXXP Releases Some General Purpose Capacity

    • (which could be consumed by your latent demand!)

    • Improved Performance: Higher Trans Rates, Faster Response

zXXP is NOT a Performance Solution

  • zXXPs are Software Pricing Solutions

  • There is Additional Overhead in z/OS to

Dispatch the Work onto the Specialty Engine

  • Certainly There Are Exceptions

    • Adding zXXPs Without Removing GPs Will Provide More Computing Resources Than GPs Provided Alone

    • More Engines Could Lead to

      • Improved Performance

        • These are “real” engines, they are as powerful as the others

        • Except they can only executed a specific type of work

      • Reduced Cost
