IBM z Pricing Strategy

z MILESTONES

In green: the pricing methods impacted by ASC

MSUs for Software Pricing MSU:

Metric used for capacity sizing capacity planning software pricing

Techies understand MSU as a Capacity metric Software Asset Manager or Purchase Manager understand MSU as “$$$” Capacity Planners have a MSU transversal view (Capacity & Cost)

How to target the real capacity in MSUs of CPCs: LSPR (*) : z Systems ITR ratios for IBM processors Cheryl Watson CPU Chart

IBM publish only Software MSU and stopped to publish Hardware MSU.(*):Large Systems Performance Reference for IBM z Systems

z Pricing Strategy: the Charter Before 2000:

Full Capacity Pricing Some leverage as PSLC, ULC, etc..

Then, the Mainframe Charter: The three pillars of the mainframe charter

Innovation == z Technologies Investment Community == increase the mainframe skills Value == lower the MF Cost (software and hardware cost)

The « Value » pillar: You pay for what you use in MLC

=== xWLC (variable Workload licence charge)=== Soft-Capping feature to control the billing level

Sub Capacity Report Tool: Charged on monthly usage in MSUs monthly based by computing the highest hour in the month per

product.

z Pricing Strategy: Based On…. Based on the Growth:

More MSUs you use, less is the MSU price Attractive pricing methods:

PSLC,IWP,CMP … New Workload Incentives pricing methods:

MWP,zCAP,zNALC… The practice of discounting MSU:

Through Technologies Dividends before z196 Through Technologies Update Pricing (TUP or TTO) from z196 to z13 Mobile zCap

Based on new technologies: Benefits of Technologies Dividends

Based on Pricelist: Software prices increase yearly or every 2 years.

Based on Enterprise Agreement: The Volume allows to get money ready to re invest

z/OS Pricing Overview: Monthly License Charges (MLC)

Including right of use and support The base of the IT Systems:

zOS and childrens as RMF,SDSF,DFHSM,RACF,etc.. CICS,IMS,DB2,MQ and Websphere,PL/1,Cobol,etc..

Several options for large (Enterprise class) machines: AWLC, CMLC, FWLC, PSLC, ULC, WLC

Several options for small (Business class) or new workloads: AEWLC, CMLC, zNALC, zELC, SALC, EWLC, FWLC, TWLC, ULC, IWP, GSSP

Charged on monthly usage in MSUs based on 00:00 on the 2nd day of the month through 24:00 on the 1st day of the next month

International Program License Agreement (IPLA) One-time charge (OTC) up-front plus Subscription and Support (S&S) each year Value Unit pricing is based on some metric such as MSUs, etc. Product Tools as Data Management Tools, CICS & IMS Tools, DB2 Tools,

Netview,Omegamon/Tivoli,TWS, Debug Tool,….

Both support Full-Capacity and Sub-Capacity charges

z/OS Pricing Overview Old Pricing Options

PSLC - Parallel Sysplex License Charges ULC - Usage License Charges

Used for DB2, CICS, IMS, WebSphere MQ if they have small usage (< 10% of CPC)

Not compatible with xWLC

New Options: CMP - Country Multiplex Pricing with CMLC (October 2015):

To control the Growth To avoid the PSLC constraint

MWP - Mobile Workload Pricing (May 2014) Can reduce the impact of mobile workloads by up to 60% (May 2014)

zCAP - z Systems Collocated Application Pricing (April 2016) Incentive pricing for new workload

Pricing Methods MLC & SYSPLEX Options:

PSLC (Parallel Sysplex Licence Charge): to aggregate pricing in parallel sysplex = one invoice The rule is to have a sysplex running on more than one machine and consuming

more than 50% per machine. Technical Constraint for Outsourcers or some of customers:

How to keep a sysplex consuming more than 50% every time CMLC (Country Multiplex Licence Charge):

Allows combining products from multiple LPARs in different sites within one country without the requirement for a parallel sysplex (PSLC Rule of 50%)

CMP is designed to reduce the cost of growth. The Baseline: the last 3 months MSUs and software bills are averaged and those

values are used to create baselines This Baseline will determine the future bills.

MLC and Incentive Options: IWP (Integrated Workload Pricing):

allow adding a workload to an LPAR without increasing the MSUs for all other work on that LPAR (not really used on the field)

Pricing Methods MLC and Incentive Options:

MWP (Mobile Workload Pricing): Need to identify/tag the Mobile transaction and consumption 60% discount on MSUs consumed by transactions that originated on a

mobile device. Calculated/Valued a posteriori through MWRT (SCRT with Mobile feature).

zCAP (z Collocated Application Pricing): Provide a financial incentive to deploy new applications on z/OS. Must be a new application to z/OS in the enterprise. zCAP Discount for a new application using MQ (for example):

Pay all MSUs consumed by MQ for the neww appl in the LPAR. Subtract 100% of that MSUs from every other IBM product in the LPAR Subtract 50% of that MSUs from the z/OS MSUs in the LPAR.

Calculated/Valued a posteriori through MWRT (SCRT with zCAP & Mobile feature).

Pricing Methods – SCRT SCRT (Sub Capacity Reporting Tool) from IBM:

Tool used each month in order to qualify for sub-capacity charges For any of the following price metrics: xWLC, zNALC, VUE, or for

select IPLA products on z/OS Charged on monthly usage in MSUs based on 00:00 on the 2nd day

of the month through 24:00 on the 1st day of the next month , so 720 Hours.

Take into account LPAR’ Soft-Capping. SCRT runs hourly for 720 hours in the month and computes the

highest hour in the month per product. Here the rule Two Family of products are managed by SCRT:MLC

with xWLC,zNalc,MWP,zCAP,I

WP,PSLC,CMLC..

IPLA with

All tools and VUE

IBM Soft Capping Feature IBM Soft Capping is a feature which allows to control the

z/OS bill by defining for each LPAR a MAXIMUM for the average consumption of MSU (R4H): This limit is called Defined Capacity (DC).

The Soft Capping rule: When Rolling 4 Hours (R4H) becomes superior or equal to DC

then the LPAR is capped. That means that the IMSU consumption will not be able to exceed the DC anymore until the R4H becomes lower than the DC again.

When R4H > DC, IMSU is limited to DC, until R4H < DC. Example of a capped LPAR:

Soft Capping Feature – Invoicing How does IBM Soft Capping feature allow you to

control the Software bill? When using the IBM Soft Capping feature, SCRT is computed as

follows:

So it takes into account either the peak of R4H or the DC.

1 monthSCRT = MAX ( SUM ( min ( Average R4Hs , Average DCs ) )

Without Soft Capping With Soft Capping

Soft Capping Feature – Invoicing (Example)

Enterprise Agreements to frame the used methods ELA (Enterprise License Agreement):

Based on the capacity planning for MLC and IPLA: Yearly valuation of all products consumption in the Datacenter Commitement per year in Currency.

IBM’s method of providing a discount to encourage long-term agreement customer agrees to purchase A 5-year ELA has a larger discount than a 2-year ELA

ELA typically covers MLC products, OTC products,and Passport Advantage (non-Mainframe) products.

Some discounts might apply to MLC Often discounts apply to OTC Discounts always apply to Passport products

Benefits of ELA Some discounts Better for budgeting Total spending divided in even payments (monthly,quarterly, yearly) This takes a lot of effort in planning, so increasing the length of ELA reduces staff time

Enterprise Agreements and Commitments MLC Commintment into an ELA:

Monthly or Quarterly Follow-UP to control the contractual limit What happen at the end of the year with the invoicing:

In case the total of the year reaches the contractual limit: The customer need to budget the gap and pay this amount to IBM

In case the total of the year is less than the contractual limit: The customer waste money

==== capacity planning is mandatory

IPLA Commintment into an ELA: If Sub Capacity is used:

Same follow-up as MLC If Full Capacity is used:

Just pay the bill

ELA: how to define the commitment A relevant Capacity Planning is mandatory:

End Users’ Business Plan (activity evolution hypothesis) taken into account – Elaboration of a capacity plan & Servers capacity optimization – Verification of Sysplex aggregation compliance (if PSLC) Forecast of Software billing levels –

How to do it: Using CPT (CCP-Tool for Capacity and Cost Planning Tool from zCost Management)

Load hypothesis into CPT Servers capacity optimization Forecast of Software billing levels (as described above)

Yearly valuation of all products consumption in MSU Convert MSU in currencies (by using an API)

Elaboration of IT investment budgets Elaboration of optimized Software contracts (including ELA) thanks to CPT

ELA: how to follow-up the commitment How to follow-Up the MLC Commitment:

Using D4Z (from zCost Management and 4bears) monthly valuation Stacked monthly view to follow-up the trend Set the contractual limit as a targetline

Enterprise Agreements and Commitments How to respect the MLC Commitment:

Using ASC from zCost Management Set Up the CPCMAX value for each CPC linked to the contractual limit CPCMAX could be monthly adapted:

By withdrawing MSU to CPCMAX in case the commitment is in danger Or by increasing CPCMAX in case of…….

Example with a 18000 MSUs commitment in the year, so 1500 MSU per month: ASC could adjust the montly limit depending of the activity while controling the yearly limit.(
