3. Right-Fitting • IT is getting crunched • Reduce cost • Improve service • i.e. “Do more w/less!” • Efficiency Efficiency Efficiency • Optimization Optimization Optimization • Server Virtualization to the Rescue • As though picking the optimal server was not already hard • Right-Fitting • A function of (assets, workloads, skills, time, cost, risk) • And of course “functional” and “non-functional” requirements!

4. As a Percentage of IT Spend - Hardware costs have plummeted - Software costs have increased - People costs have exploded - Other costs are taking off Costs have changed dramatically 1995 Hardware Other Based on IBM Server Consolidation Engagements People Other Hardware Software Total Cost of Acquisition Analysis Used to capture 80% of spend. It is down to less than 50%. People Software Present

5. Because IT Complexity Drives Many Hidden Costs • Managing today’s mixed IT platform environments can be complex and costly • Thousands of servers • Underutilized assets • Thousands of software licenses • Thousands of distributed control points • Ineffective costing methodologies • The Result • Massive complexity • Spiraling people costs • Increased availability and downtime costs • Increased security breach costs • Sub-optimal investment choices Source:IDC

7. RACEv History and Overview

8. Origins of RACEv • Introduction of CMOS and Specialty Engines into System Z • Changed value proposition • Select group of individuals started working on cross-platform sizing comparisons • Originally tightly controlled, over time began speaking openly with customers • Large number of sizings and comparisons • Customer Requirements for Right-Fitting Applications • Confusion among platform choices, needed a way to make decisions • Account teams began working with customer to develop tools to assist • IBM Management focused on growing System Z • Directed two individuals to find better way to drive new workload onto System Z • Many fits and starts • Needed to shorten sales cycle The “RACE Core Team” was born

9. What is RACEv • IBM Pre-Sales technical support program • Bring “total cost oriented” (aka TCO) tools to IBM sellers and customers • Fee-free customer offering • IBM Internal Use Only tooling • Acronym: • “Right-Fitting Applications into Consolidated Environments” • V is for virtualization • RACE Core-Team • Terry Weinberg, Bob Neidig, Bob Vik, Eduardo Oliveira, Scott Lundell, and Monte Bauman • World-wide community of practitioners • Originally geared for System Z, now used cross platform

10. What is RACEv • RACEv is both a framework and a tool • Implemented as a spreadsheet • People tend to distrust “black boxes” • Highly customizable • Two major functions • Cross platform sizing • TCO Modeling • Tries to bring platform decisions to a common metric -- Money

11. RACEv Major Functions • Cross Platform Sizing • Includes constraint analysis • TCO Modeling

12. Cross Platform Sizing

13. Memory SAP C C C Disk P P P Simplified Computer Architecture Front side bus C Cache design can have a great impact on performance and workload characteristics

14. Reported BW Zero C-C Bus Speed Zero Internal Bandwidth Example Shared Cache C-C Bus Private Cache Memory Cache Processors Effective BW C-M-C Speed C-C Bus Speed Infinite

15. Single system capacity is determined by: Processor speed Memory hierarchy I/O structure What determines system capacity There's more to performance than just processing power CPU Busy I/O Busy CPU Time Memory Time I/O Time Processor, memory, and I/O times vary greatly by application and by machine type

16. Memory Time I/O Time CPU Time zSeries CPU Time Memory Time Others I/O Time Relative single system capacity There's more to performance than just processing power Data Intensive Workloads CPU Busy zSeries Memory Time CPU Time I/O Time CPU Time I/O Time Memory Time Others Compute Intensive Workloads

17. Cross Platform Capacity Method • Capacity Metric can vary (MIPS, MHz, tpm, tpc-c, n° engines, ...) • Value of WLF corresponds to units of capacity • WorkLoad Factor difficult to measure • not enough benchmarks to cover all the cases • driven by cache miss rate, which cannot be directly measured • “Cloud of uncertainty” around measured values • Accuracy vs. Precision • Pathlength reductions need to be accounted for separately IBM Patent obtained on this method

18. Cross Platform Methodology • Multiple “before and after” measurements taken over the years • WLF derived from measurements • Values varies by an order of magnitude from high to low • Sizings done with CPU utilization • Assume CPU is limiting factor (Good assumption when going to zSeries) • Differences in I/O, memory, CPU speed, bandwidth, etc. accounted for by WLF • “Data-mining” of measurements leads to broad categories • Use broad categories to predict future relationships • Need to account for utilization differences and “peaking effects” • Total amount required is seldom the “peak of peaks” • Typically see 30-60% reduction in requirements • Overhead needs to be added for hypervisor • Both true overhead, and loss of efficiency

19. System z Workload Migration Characterization 10. CPU Intensive – e.g. numerically intensive, etc. 9. Protocol Serving – e.g. static HTTP, firewall, etc. 8. Skewless OTLP – e.g. simple and predictable transaction processing 7. Java Heavy – e.g. cpu intensive java applications Superb Candidates for System z 6. Java Light – e.g. data intensive java applications 5. Database – e.g. Oracle DBMS ordynamic HTTP server More Challenging for System z… But z196 is a game changer 4. Mixed High – e.g. multiple, cpu-intense simple applications 3. Mixed Low – e.g. multiple, data-intense applications or skewed OLTP, MQ 2. I/O Bound – e.g. high I/O content applications 1. Data Intensive – large working set and/or high I/O content applications

20. A Server Characterization Approach http://www.ideasinternational.com/ • Comprehensive source of cross-brand server performance • Tracks and licenses server research on all major vendors • Built into the RACEv tool set

21. Sizing Methodology • Also need to count for peaks and valleys of servers • Servers seldom all peak at the same time • RACEv uses two different methods to estimate “peak smoothing” • Statistically based • Can be overridden if real data available

27. Target Cases Analysis Summary Analysis Inputs Case 1 Target Servers Server Server Server Server Case 0 Subject Servers Case 2 Target Servers Server Server Server Server Server Server Server Server Case 3 Target Servers Server Server Server Server Server

28. RACEv Subject Cases • CASE 0 - the “Input Case” - the “Subject Servers” • The servers that are subject to being virtualized. • Two “types” of subject servers: • Brown-field • A set of “existing” servers that are subject to being virtualized). • Green-field • A set of “new” servers that are candidates to instead being built new as virtualized servers.

29. RACEv Costing Categories (1) Energy • The cost of watts to power and cool servers • Nameplate watts converted to steady-state watts for accuracy (2) Floorspace • The cost of floorspace • Floor-standing, rack-mounted, or blade-chassis rack-mounted • each are carefully/separately accounted for (3) Facilities • Cost of new or updated datacenter facilities • CDUs, PDUs, datacenter expansion, new datacenter, etc. • (RACEv input field) (4) Migration • Cost of migrating subject servers to target (virtual) servers • (RACEv input field / IBM Server Makeover Team Link) (5) Engineering • Cost of engineering (building) target server infrastructure • (RACEv input field / IBM Server Makeover Team Link)

32. RACEv Costing Categories (continued) (14) Network Bandwidth • The cost of bandwidth consumed on the physical network (mostly engineering costs) • Different companies have different concerns and costs regarding bandwidth • RACEv helps assess the degree to which various virtualization technologies are able to remove bandwidth consumption from the physical network (15) Administration • The cost of people required to administer the physical layer, the hypervisor layer, and the operating system layer of each case's configuration • RACEv assimilates the full-time equivalents (FTE) ratios associated with various technologies against target configurations to derive a estimated cost of administration (16) Disaster Recovery Equipment Acquisition • The cost of additional equipment required for disaster recovery configurations • RACEv provides easy/automated mechanism with suggested parameters for adding DR equipment in equal measure to “production” equipment configured (17) Disaster Recovery Equipment Operation • The cost of operating the acquired disaster recovery equipment • RACEv provides easy and accurate assessment means to account for total cost of operating additional equipment – aka power space connectivity maintenance etc.

33. RACEv Costing Categories (continued) (18) Outages • The cost of server-based outages • Lost sales • Lost payroll • Overtime paid during recovery • Penalties paid • Also handles growth and tech refreshes • Individual cost categories can be turned on or off • All values are either inputs or can be overridden • Up to 10 Target Cases supported WOW... 18 categories of cost! Pretty complete... What did we miss?
