1 Mainframe Cost Optimisation How to make friends and influence people with your mainframe

2 Terminology - License To legally execute software, you must have a LICENSE for the machine The license will also stipulate the pricing metric - MSU Millions of Service Units Measure of how much processing that can be done in an hour IBM publishes MSU ratings for all hardware - Service Unit Simply a measure of power Bag of chips or Box of biscuits - Rolling 4 Hour Average MSU consumption averaged over a rolling four hour period Copyright 12/11/2013 BMC Software, Inc 2

3 Monthly License Charge/Subcapacity Pricing Pricing CAN be based on machine capacity But Subcapacity Pricing allows you to pay for what you actually use - NOT on machine capacity Based on the Rolling 4 Hour Average PEAK for the month Notice, it is NOT based on individual software usage - See later Also see A Planning for Subcapacity Pricing Copyright 12/11/2013 BMC Software, Inc 3

4 Basics of IBM Software Monthly Licensing Charges AWLC (Advance Workload Licensing Charges): zenterprise, EC12 - WLC (z10, z9, 990) Includes the following: (OS, JES, RMF) DB2 Websphere MQ Full-Capacity AWLC: charges are based on the full capacity where each AWLC product executes Other 10% Hardware 20% People 25% IBM MLC Software 35% ISV 10% IBM OTC 5% Sub-Capacity AWLC: charges are based on the utilization of the LPAR or LPARs where an AWLC product executes - Charges determined by the monthly peak 4 hour rolling average - ALL cpu consumption counts towards this average Copyright 12/11/2013 BMC Software, Inc 4

5 The 4 Hour Rolling Average Calculation: A Trailing Indicator MSU Utilization 4 Hour Rolling Average Actual Peak MSU Utilization: 534 MSUs Peak 4HRA: 468 MSUs :00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 Copyright 12/11/2013 BMC Software, Inc 5

12 How does this information get to IBM? Customer creates reports using Sub-Capacity Reporting Tool (SCRT) This uses SMF type 70 records to determine configuration details and overall system usage And SMF type 89 records to determine individual product usage The SCRT report is submitted to IBM monthly Copyright 12/11/2013 BMC Software, Inc 12

14 Savings possibilities There are many ways that we can save money in this scenario We can stop consumption over a certain level We could reduce cpu consumption around the peak We could move MLC software entirely off an LPAR We could approach our tuning in a totally new way Copyright 12/11/2013 BMC Software, Inc 14

15 Capping Set a ceiling on MSU usage Now, consumption cannot exceed a pre-defined level If a workload does try to exceed the limit, it will be held back Which is worse - Having a surprise bill from IBM - Having response time issues due to capping Copyright 12/11/2013 BMC Software, Inc 15

34 Workloads and MLC What else can you do to affect MLC charging? Continuously running tasks are they as efficient as possible? Are there any workloads that don t HAVE to be executed at that time? Could some batch or housekeeping be rescheduled? What can moved to another LPAR Anything you can remove (or delay) will have an immediate effect on the size of the R4HA peak Establish a balance between Performance and MLC charges Copyright 12/11/2013 BMC Software, Inc 35

35 Workloads and MLC Considerations Any MLC software that is ACTIVE during the peak will be charged If you don t NEED /, DB2 etc to be up, then don t keep them up Active but not being used costs money Inactive (down) does NOT Copyright 12/11/2013 BMC Software, Inc 36
