6. Top 5 Tech Areas Against Exadata 1. Complex Oracle Exadata Architecture Shared memory & disk. Limited scalability and unpredictable performance Two tiered architecture complexity (indexes/scans) Exadata is proprietary and expensive. Price discounting will slow 2. Complex Oracle RAC RAC node management Stability Issues with high workloads and (15+ way setups) Complex transition from non RAC environments 3. Poor Workload Management Conditional parallelism causes unpredictable performance Lack of mission critical SLAs Lack of dynamic resource control and hardware utilization 4. Struggles with Mixed Workloads Optimizer maturity, complex queries and high concurrency 5. Higher Risk and Support costs DBA support (tuning, indexes, workload mgmt etc.)6 >

Teradata Shared Nothing vs. Oracle Shared Disk Teradata Oracle (RAC) P P D M D M P P B B B B B B M D M D Node 1 Node 2 Shared nothing = no resource Shared everything = resource contention contention Parallelism is unconditional and Parallelism is conditional and predictable unpredictable Linear scalability with a slope of one Scalability with diminishing returns7 >

10. Exadata Support Issues Significantly higher learning curve than claimed > 285 days of new DBA training for existing Oracle DBAs, Role of DBA changes > Must re-evaluate indexes, tuning and workload choices > Customers taking 8-12 months to move into production High levels of patching > Monthly database patch and quarterly storage image update > Often necessitating System Restart > Unpredictable system stability and performance variation Manual workload management and query control > Workload Management for Oracle Exadata is difficult to learn & maintain > Demotion of problematic workloads is difficult with Exadata due to the fact that resources cannot be freed up dynamically > Oracle compensates by recommending artificial limits to jobs (before they even start) > Exadata is designed and tuned for restricted workloads, batch reporting and concurrency levels below 30 conc. Queries > TD13 has a significant RDBMS lead on Exadata & Oracle 11g on EWD workloads10 >

11. Top Exadata Claims against Teradata 1. Infiniband is faster than Teradata BYNET Irrelevant argument we move data differently Higher on 6650 and almost equal on 2650 2. Oracle Smart Flash delivers industry leading query throughput Cache good for OLTP random workloads, not table scans Ingest rate of RAC nodes half of flash scan rate 3. Hybrid Columnar Compression provides 10-50x compression Real world numbers of 4-6x seen Teradata ALC & BLC offer equivalent compression with greater flexibility of choice Teradata near future will offer additional compression options 4. Exadata provides consolidation platform and end to end solution ERP and DWing workloads unlikely to occur on the same platform Need to focus on best in class solution and not settle for less11 >

14. Oracle Marketing ClaimsAnd Counterpoints

15. Softbank Mobile Claims and Counterpoints Same reference ad shown 4 different ways! Oracle Claim Response 2 racks of 2650! The Teradata systems were very old by 36 racks of Teradata todays standards (circa 2003). Those 36 racks were systems were roughly equivalent to only two racks of 2650 given the replaced with 3 dramatic performance and packaging advances made by racks of Exadata Teradata since that time. 660X performance improvement was realized by a US hospitality company after migrating from Oracle to a Query performance Teradata Data Warehousing Appliance. The Oracle claim increased 8X for Softbank Mobile compares Oracles Exadata system to the old, production Teradata system. What do those comparisons mean? Our current 2650 platform is greener than Exadata on 1/10th of the energy both a rack to rack basis and on a performance equivalency consumed basis. (See chart below.) This is false. In fact, based on a variety of sizing metrics such as customer data volume, spinning disk, TPerf or Softbank Mobile was nodes Softbank Mobile is not even in the Top 20 Teradata Teradatas largest systems or customers in Asia! It is true that Softbank Mobile customer in Asia. was, at the time, the largest Teradata customer in Japan not Asia.15 >

16. Teradata is greener than Exadata on a cabinet-by-cabinet basis AND on a performance equivalency basis. Teradata Data Warehouse Appliance Oracle Exadata X2-2 2650 Full Cabinet (9 nodes) Full Cabinet Power 7080 watts 14000 watts Heat 27k BTUs/hr 47k BTUs/hr Weight 1540 lbs 2131 lbs/rack Source is Teradata 2650 prep guide and Oracle Exadata X2-2 data sheet. Looking at Teradatas recommended config of 15n, 2650 vs. one full rack of Exadata X2-2, then the numbers are: Teradata Data Warehouse Appliance Oracle Exadata X2-2 15 nodes (5 cliques) Full Cabinet Power 12760 watts 14000 watts Teradata Data Heat 45k BTUs/hr 47k BTUs/hr Warehouse Appliance 2650 Weight 2571 lbs 2131 lbs/rack Oracle Exadata X2-2 2650 vs. X2-2 Were 2x better per rack on power, and approximately 15% better on a performance equivalence basis (15 nodes). Were just under 2x better per rack on cooling and16 >

17. The Bigger Picture: Teradata is Winning the Migration Battle Large number of Oracle migrations since the launch of Exadata The number of migrations doubled in 2010 Oracle attack advertising appears to be actually helping Teradata recognition and product evaluations Less than a handful of Teradata replacements. > Mostly due to political or consolidation reasons. Teradata has now migrated well over 250+ customers Our overall win rate is near our all time high17 >

18. Oracle is not Teradata Technical Differences Teradata Oracle Shared Nothing Architecture Shared Disk Architecture Data Linearly scalable, Easily Managed access management overhead, Single System Image more complex system mgt Pervasive, Always On Parallelism, Bolted-on parallelism is conditional, designed in from the beginning unpredictable, and harder to use Superior Cost-based Optimizer Performance depends on query- and query executor produce robust specific indexes and tuning options, results regardless of SQL complexity and even optimizer hints Mixed Workload Management Different workloads split onto marshals system resources to meet separate nodes of RAC system SLAs of diverse tasks on one system Ease of Use automatic resource Toolkit approach is complex to mgt. yields quicker time to value setup, execute and maintain Multi-dimensionality scalability Limited ability to scale along one or of data and user volume, workload two dimensions at a time mix, volume and complexity18 >

32. Summary

33. What to Say About Exadata Oracle Exadata is proprietary > They are directly attacking HP and IBM > Their former tactic of claiming Teradata to be proprietary is no longer valid Oracle Exadata can be expensive Oracle Exadata is complex > RAC, shared data architecture now complicated with a function- specific Exadata layer > Exadata has 285 days of training (2 years) > High Risk due to complex tuning and bug patching > Impossible to run at 100%, even 50% is a challenge > Indexes? Compression? > Mixed workload concurrency? > Workload vs node management? (Not virtual like Teradata) Current Exadata implementations are OLTP or simple reporting like typical Oracle Classic data marts33 >
