6. A well-managed Datacenter • Significant growth of Datacenters • New jobs such as  Software Cost Planner (just like  Capacity Planner which emerged a few years ago)

7. How Many Pricing Models ?! • Monthly license Charge (MLC) Pricing • Software charges are determined by the capacity of the CPC in which the product runs • Examples are : Parallel Sysplex License Charges (PSLC) and zSeries Entry License Charges(zELC) • SubCapacity Pricing • Software charges are determined by utilization capacity of the LPARs in which the product runs • Examples are: Workload License Charges(WLC), Entry Workload License Charges(EWLC) and Midrange Workload License Charges (MWLC) • And more and IPLA International Program License Agreement(IPLA), System z New Application License Charges(zNACL), Value Units, CBU’s , Select Application License Charges(SALC), Execution Based, Reference Base, z/OS based….. • http://www-03.ibm.com/systems/z/resources/swprice/mlc/wlc.html

12. VWLC - the R4H The R4H represents the average consumption (in MSU) of the LPAR during the last 4 hours= Average of the last 48 IMSU metrics. R4H 250 R4H 120 LPAR 1

13. VWLC – IBM Sub Capacity Reporting Tool • SCRT (Sub Capacity Reporting Tool) is a tool used by IBM for z/OS billing. • It uses the following SMF records : SMF 70-1 and SMF 89-1 / 89-2 • The SCRT is computed on a monthly basis : • During the month (from the second day of the month at 0h00 to the first day at 24h00 of the following month) • R4H averages are calculated for each WLC products, each hour, for each LPAR, for the month.

14. SCRT feature – Invoicing (Example) • the IMS bill reports 318 MSU at the same date and time with only LPARD & LPARP • The COBOL bill reports 91 MSU with only LPARD and at different date and time: February, 15th at 10:00

15. VWLC – IBM Sub Capacity Reporting Tool SCRT = MAX ( SUM( Average R4Hs )) 1 month LPARs per LPAR

16. vWLC, you just paid from what you used, now how do I control it? IBM Soft-Capping feature But I hear that impacts performance ! And it not with Defined Capacity = 0

17. IBM Soft-Capping feature • IBM Soft-Capping is a feature which allows the control of z/OS bill. • This limit is called Defined Capacity (DC) • The Soft-Capping rule: • When Rolling 4 Hours (R4H) becomes greater than or equal to DC then the LPAR is capped. That means that the IMSU consumption will not be able to exceed DC anymore until the R4H becomes lower than the DC.

18. Where is the SoftCap set? Hardware Management Console (HMC)

19. IBM Soft-Capping feature • Example of an LPAR which is capped:

20. An example of how you control your costs with Soft-Capping Defined Capacity = 0

21. You don’t !

22. An example of how you control your costs with Soft-Capping Defined Capacity = x

23. Soft-Capping feature – Invoicing Example Without Soft-Capping With Soft-Capping

24. Soft-Capping feature Defined Capacity being used 100 • Here, Cobol runs only on SYVA. SCRT displays 100 MSU because it retained the DC of 100 since the R4H was higher. 100

25. An example with Soft-Capping when using Group Capacity Limit

26. Group Capacity Limit • Group Capacity Limit is an extension of Defined Capacity • It allows an installation to define a “softcap” for multiple logical partitions on the same CPC • The group limit is a defined capacity for all partitions defined in the group • A “CPCMAX” for group of LPARs to share • Created on the HMC • Can help reduce “softcapping” • Creates it’s own problems

27. Group Capacity Limit

28. Soft-Capping feature Group Capping limit • For z/OS, the CPC peak is 993 MSU on January, the 5th at 12H and GCL overrides this value by 910 on January, the 4th at 12H : why? Because it is the first time (15) in the month GCL has been activated

32. VWLC with Soft-Capping: LPAR view • IMSU : Instantaneous consumption of MSU for the LPAR • R4H : Average of IMSU in 4 consecutive hours. • DC : Defined Capacity, billing limit that you do not want to exceed … and that you can fix at any level you want

33. VWLC with Soft-Capping: LPAR view • IMSU : Instantaneous consumption of MSU for the LPAR • R4H : Average of IMSU in 4 consecutive hours. • DC : Defined Capacity, billing limit that you don’t want to exceed … and that you can fix at any level you want • But performance can be affected (capping  IMSU is brought back to the DC) !

34. vWLC – IBM Sub Capacity Reporting Tool SCRT = MAX ( SUM( Average R4Hs )) 1 month LPARs per LPAR SCRT = MAX (SUM( min ( Average R4Hs or DC ) ) ) • With Soft-Capping it takes into account either the peak of R4H or the DC.

35. VWLC with IBM Soft-Capping: Pros & Cons • VWLC with IBM Soft-Capping: • IBM Soft-Capping is easy to setup on the machine • It allows you to control the bill at a chosen level (by fixing DCs) • VWLC with IBM Soft-Capping: + / -

36. Q&A

37. Group Capacity Limit

38. Group Capacity Limit • Group Capacity Limit (GCL) introduced in 2008 • ShareW% This is the %SHARE calculated from the WEIGHT of the LPAR • ShareW_GCL% This is the %SHARE calculated from the WEIGHT in the GCL of the LPAR • ShareD% %HARE calculated from the DEFINDED CAPACITY of the LPAR • Target MSU from Weight: ShareW% translated in MSU • Target MSU from GCL Weight: ShareWGCL% translated in MSU
