Moss Introduction - Agenda Typical IBM Mainframe Expenditure Profile Software Asset Management Evolution IT & Software Asset Management Interaction Do You Know Your z/os Software Portfolio? Software Cost Reduction: Why Bother? Market Comparisons: What Information Is Out There? New Mainframe Workloads & Others TCO Reduction Options: 1) Sub-Capacity Pricing: VWLC 2) Software Contract Negotiations 3) MIPS/MSU Reduction Techniques 4) Simple Product Replacement 5) CPU Reduction: Application Tuning 6) Considered Product Migration 2 Typical IBM Mainframe Expenditure Profile zseries TCO Analysis zseries TCO Analysis % 10% 25% 40% Software Hardware People Other 43% 10% 27% 20% Software Hardware People Other Source: zjournal January 2009 Source: IBM May 2006 Software expenditure increases over time and by ~50% in 4 years zseries servers might be a commodity, sourced only from IBM Year-on-year, Mainframe personnel manage more resources! Software expenditure is significant, so why not optimize usage? 3 Software Asset Management (SAM) Evolution #1 The Traditional/Typical Model Identify Acquire Sunset Replace Software Asset Management Process Use Maintain Renew IT Department Procurement Department Historically, which business group handled software negotiations? Historically, were all software purchases business case justified? Today, TCO, ROI and compliance justify the need for a SAM process Why is compliance mandatory, but cost reduction optional? 4 Software Asset Management (SAM) Evolution #2 Identify Acquire Sunset Replace Software Asset Management Process Use Maintain Renew SAM can tell you more about your own business than you think SAM puts you on an even footing for equitable vendor negotiations A successful SAM process will be self-funding, not another overhead Many companies have delivered good cost savings with SAM! 5 Asset Lifecycle Management IT & Software Asset Management Interaction Accurate Inventory SW License Management Total Cost of Ownership Software Asset Management Purchasing Vendor Contracts Business Services Costs Financial Management IT Asset Management Leases Warranties Maintenance Asset Costs Audit Readiness Service/Support Agreements Disposal External Audit Internal Audit Don t lose sight of the big picture, IT Asset Management 6 Do You Know Your z/os Software Portfolio? DORANA SoftAudit MRO TADz - Tivoli Asset Discovery for z/os TAMIT - Tivoli Asset Management for IT IBM acquires Ubiquity & ISOGON, reducing to 1 Tivoli product IBM acquires Maximo for MRO Asset Management function z/os Software Auto-Discovery Tool What software is installed; Who uses it; Why is it used; When is it executed, Where is it installed; How With this inventory information, you re empowered to make the best software decisions, because it s your business! Software Asset Management should be evolutionary as opposed to a radical revolution. Inventory your environment, and then ISV negotiation becomes a whole lot easier Software usage compliance is just as good for you as it is for the ISV! Duplicated or redundant software is typical after nn years MVS use Information is not power, it s empowering; empower your business! Software usage via Auto-Discovery is the best starting place for SAM 7 Software Cost Reduction: Why Should We Bother? Sample IBM zseries Server Pricing Configurations Using Industry Standard Pricing 75 MSU - ~500 MIPS 150 MSU - ~1000 MIPS Program # Software Description MLC Program # Software Description MLC 5635DB2 DB2 for z/os ~ 15, DB2 DB2 for z/os ~ 22, M15 CICS TS for z/os ~ 16, M15 CICS TS for z/os ~ 23, A01 z/os V1 Base ~ 22, A01 z/os V1 Base ~ 40,000 IBM WLC Total Monthly Cost ~ 53,000 IBM WLC Total Monthly Cost ~ 86,000 IBM WLC Annual 10% ~ 63,000 IBM WLC Annual 10% ~ 103,000 But, Industry Averages State ~$2,000-$5,000 (~ 1,500-3,500) Cost per Year for Software MIPS Total z/os Software Annual Cost ~ 750,000 Total z/os Software Annual Cost ~ 1,500,000 Total z/os Annual 10% ~ 75,000 Total z/os Annual 10% ~ 150,000 Core z/os products are a significant component of overall cost Reducing MIPS/MSU consumption is of course the biggest saving! MIPS/MSU prices reduce year-on-year, but software stays the same Even for a small user, 10% savings are conservative & worthwhile! 8 Market Comparisons: What Information Is Out There? There is no compare-the-market web site, but: If you know what software you use, contract negotiations with the ISV will be much easier & you can have major influence in discussions If you re using legacy products with stabilized function, search the market for alternatives, they do exist, maybe from smaller ISV s with flexible pricing (E.g. Subscription based) When was the last time an ISV called you proactively and offered a no cost education session to safeguard you re getting value from their and thus your software solution? You pay ~15-25% support costs per year, get bang-for-your-buck! ISV s wait for compelling events, keep them on their toes Collaboration is the key, a value based customer & ISV relationship! It s good to talk, so talk with the incumbent & perhaps other ISV s 9 New Mainframe Workloads & Others zenterprise 196 (z196) System z Solution Editions: Cost efficient integrated offerings combining servers, Middleware, maintenance and storage: ACI (Electronic Payments) Application Development Chordiant (Customer Experience) Cloud Computing Data Warehousing (DB2) Enterprise Linux (Virtualization) GDPS (DR/Availability) SAP Applications (DB2) WebSphere (SOA) Saints or Sinners - Radar Screen Observations: TurboHercules: Mainframe emulation for small users or DR solutions, building on Hercules foundations. NEON zprime: Offloads CPU resources to speciality engines. Mantissa Corporation z86vm (z/vos): Utilizes z/vm to potentially host Windows images. TmaxSoft OpenFrame: Rehost traditional Mainframe workloads on IFL engines. Could zbx bring a meeting of IT Management minds? Mainframe, UNIX, Linux & Windows The IBM System z Solution Edition Series offers special package pricing for their most popular solutions that is competitive with other ISV/IHV alternatives, delivering outstanding ongoing cost of ownership (TCO) with a low acquisition cost (TCA), but of course, there s znalc also. Only you can decide, but please perform comprehensive due diligence, and as always, all that glisters is not necessarily gold! Choose the best TCO option from day #1 and research the market! 10 Sub-Capacity Pricing: VWLC #1 Sub-Capacity Pricing Checklist: Obtain internal organizational support Engage your IBM account team, talk with them about your plans to investigate WLC scenarios Create a software inventory Consider Capacity Planning forecasts Define a current baseline CPC usage report Perform a Sub-capacity Analysis, either IBM SCPT/SCRT and/or LCS from Al Sherkow Determine WLC benefits for 1, 2 & 3 year terms, from planning and forecast data Decide whether WLC is right for you Engage your IBM account team, talk with them about WLC T s & C s The worst question is the question not asked;start asking questions! Communicate with your suppliers, start as you mean to go on Even if WLC is not for you; learn even more about your environment Software savings: Sub-capacity planning is the best place to start! 11 Sub-Capacity Pricing: VWLC #2 Workload Charges Summary: Grow hardware capacity without necessarily increasing software charges Support for most zseries server configurations Once WLC is chosen, PSLC or ULC pricing structures no longer apply Lower cost for incremental growth Usage based pay for what you use pricing Full Capacity (CPC) WLC structure or Sub Capacity (LPAR) pricing for eligible products, z/os, CICS, DB2, IMS, MQ, Debug Tool, COBOL, PL/I, SA, Netview, OPC/TWS, Domino, QMF, Encryption Facility This example is for a 2 LPAR 119 MSU CPC. LPARA has an R4HA of 73 MSUs, LPARB 52 MSUs and an aggregate of 98 MSUs. Thus the customer would be charged for 98 MSUs usage. The LPAR utilization capacity is the highest sum of measured four-hour rolling MSU averages for the LPARs in the CPC in which a sub-capacity eligible product runs concurrently during a given month. The peak interval is the highest utilization determined from the sum of the utilization for all LPARs in which a particular product ran in a given hour. Pay for capacity on a R4HA, not on the maximum capacity reached! If MSU usage decreases or is seasonal, billing is proportional Most customers benefit from VWLC pricing, by ~5-10% per annum Usage based pricing should apply to all ISV software, not just IBM 12 Sub-Capacity Pricing: VWLC Soft-Capping Evolution VWLC Price vs. Performance Observations: Some customers require billing certainty, the Defined Capacity (DC) metric introduces softcapping for LPARs, which can impact performance! Aggregated granularity can be applied to multiple LPARs with the Group Capacity Limit (GCL) function, optimizing costs, but does not address the price vs. performance challenge An IBM recognized VWLC optimization solution, AutoSoftCapping (ASC) monitors R4HA activity, allowing a customer to define an MSU resource usage policy, dynamically managing DC metrics, transferring MSU resource between LPARs! Only you can decide, what is most important, price or performance? Many customers find a good balance using standard VWLC & GCL Cost optimization without performance impact is possible via ASC! By definition R4HA includes unused MSU resource, which can be used! 13 Software Contract Negotiations: The Enterprise Word! Enterprise Software Contracts Good savings are possible, but balance risk with reward and beware of the compelling event; maybe consider deploying an external consultant 14 MIPS/MSU Reduction Techniques IBM Speciality Engines; ziip & zaap Introduction Requires z9, z10 or z196 hardware architecture zaap was originally targeted for Java workloads, now includes XML parsing ability ziip offers more MSU offload capability largely based on SRB enclave type applications IBM software that is ziip eligible includes DB2 Connect, DB2 Data Serving, DRDA, Parallel Queries, DB2 Utilities LOAD, REORG, and REBUILD INDEX functions; Communication Server IPSec; XML System Services; Global Mirror (zgm); HiperSockets; Common Information Module (CIM) ISV software that is ziip eligible include utility tools, SOA solutions, XML processing (E.g. SQL) ziip/zaap analysis is uncomplicated and based on your CPU usage A speculate to accumulate implementation, but ROI is short-term Delivers system-wide benefit, releasing General Purpose CPU cycles! Arguably a workload runs for free on a ziip or zaap speciality engine 15 Simple Product Replacement Systems Management/Utility/Tool: No application data or code Data/Subsystem Management: Level 2 data Application: Database Code Systems Management/Utility/Tool Observations: Typically each and every product can be replaced by several competitive products An incumbent product will have been purchased, OTC, IPLA, et al, or is on a monthly rental/lease; but most smart ISV s will replace a product with subscription based licensing An incumbent product might be decades old, not benefitting from enhancement, whereas another competitive product might have higher function, use less resources and be lower cost From the larger ISV s you might have nn software products installed; maybe converting just 1 or a few products might keep them on their toes and improve the relationship Conversions are typically straightforward and are transparent to the business, with no risk Sub-Capacity pricing should apply, so if you submit SCRT reports to IBM, the ISV should accept these also, for the relevant major IBM product; z/os, DB2, CICS, MQ, et al A better product for less cost, improved ISV relationships, why wouldn t you? 16 CPU Reduction: Application Tuning Application Tuning Observations: Many major ISV s have announced a MIPS Usage Assessment, which inevitably uses one of their own software tools, that you might have installed Over time, business applications evolve, are modified and have interoperability with major subsystems and software (E.g. RDBMS, OLTP, Disk), and so although their logic might be OK, overall performance could be improved (E.g. Batch, Query, Search, Etc.) Do you have these tuning tools installed; Strobe, ExpeTune, APPTUNE, SQL Explorer, SmartTune, TRILOGexpert TriTune, Application Performance Analyzer Automation Assistant? Then, maybe find the time to use them Significant cost savings possible, releasing General Purpose CPU Cost saving is a by-product of a faster and optimized application! You should take credit and pride in optimizing your LOB application Let Application Tuning become part of your evolving SAM discipline 17 Considered Product Replacement Subsystem Management Solution Policies/Parameters Tape Scheduler Security Sort Subsystem Data Management Solution Policies & Data Data Mover (HSM) Databases & Code Business Logic RDBMS Output Management Change Management Programmes Considered Product Replacement Observations: Typically each and every product can be replaced by several competitive products An incumbent product will have been purchased, OTC, IPLA, et al, or is on a monthly rental/lease; but most smart ISV s will replace a product with subscription based licensing The further down this list we progress, the more complex, time consuming & thus risky is the conversion. They have been performed before, by ISV s, the internal customer or consultancy companies such as RSM Partners, SystemWerx, Ithaca, but such migrations should only be considered as a last resort, for compelling business reasons. When policies & data require conversion, the GIGO (Garbage-In and Garbage-Out) principle applies. Clean-Up the current environment first; consider, if data requires conversion, it must be restored/recalled/recovered to its original non-proprietary vanilla status before displacing the incumbent product! Anything is possible, but there are easier and less risky cost reduction options! 18 z/os Software Cost Optimization: Summary Ground Zero: z/os Software Inventory Lease TADz for 1-3 Months (low cost) Step 5: Application CPU Usage Pragmatic performance tuning Step 1: Sub-Capacity Pricing Determine VWLC benefits Step 4: Product Replacement Pragmatic product swap-outs Step 2: Vendor Communication Negotiate better/flexible costs Step 3: MIPS/MSU Reduction Investigate ziip/zaap/ifl et al The longest and most difficult journey always starts with a simple first step 19 The IBM z/os Software Cost Reduction Offerings Portfolio Review & Analysis (PRA): An IBM service with a ~4 week duration that leverages from TADz (ITLCMz) software to project current z/os software portfolio costs for 60 Months (5 Years). Outputs will also review software portfolio from a Replacement, Renegotiate, Removal and Rehosting viewpoint, perhaps suggesting IBM software products Financial Management & Accounting Workshop (FMA): An onsite workshop to analyse the existing customer environment (E.g. Hardware, Software, Manpower, Facilities, Processes, et al), while delivering a best practices recommendations summary for applying FMA methodology. Total Cost of Ownership Studies (ztco/eagle): A gratis IBM service with a ~30 day duration that is specifically targeted to highlight which platform is best suited for the customers business applications. Typically ztco (AKA Eagle) is initiated when there is pressure to decommission or commission the zseries platform for cost saving reasons. Not surprisingly, IBM are well versed in this area, being zseries innovators 20
