Workload License Charges

  • How Did We Get Here?

    • Years Ago Machines Did Not Have Partitions and the Hardware was the Major Cost

    • The Software Cost was Related to the Hardware Capacity and Small

    • People Generally Agree It Is “Fair” to Pay for Software Based on What is Used

    • For Years the Hardware Size Better Matched What Sites Were Using

  • Changes in the Data Center

    • LPARs

      • Different Partitions for Portions of the Workload

    • Tools Targeted to Specific Applications: CICS, DB2, Development

      • It Becomes Apparent That When Development Uses 30% of a Machine, and the Software Cost for Development Tools is 100% of a Machine That Something is Not Fair

    • Granularity of Hardware Increments is now 250+ MIPS

      • You Cannot Buy 10 MIPS of any zBox
