4-Hour Rolling Average & Defined Capacity

  • 4-Hour Rolling Average of an LPAR

    • Smoothes Spikes in Usage

    • A Number IBM Can Base Your Bill On That is Not Always the Size of the Machine, or the LPAR

    • Your IBM Software Charges for Sub-Capacity Products Are Based on Each Product’s Simultaneous 4-Hour Rolling Averages

  • Defined Capacity of an LPAR

    • WLM Uses the Defined Capacity as a Throttle on the 4-Hour Rolling Average

      • When an LPAR’s 4HRA Exceeds the LPAR’s Defined Capacity, then WLM Tells PR/SM to “Softcap” the LPAR

      • An LPAR with a “Softcap” has WLM “CPU-Delay”

    • An LPAR Will Never Be Charged More Than the Defined Capacity
