6 Power Systems Portfolio Consistency Binary compatibility Mainframe-inspired reliability Advanced Virtualization AIX, Linux and IBM i OS Power 750 Power 770 Power 780 Complete flexibility for workload deployment Power 755 HPC

7 August 2010 Express Power systems provide the same capabilities sized right for MidMarket clients Power 740 Higher qualities of service at affordable prices The reliability, security and scalability of Power in the broadest and most affordable portfolio ever providing enterprise service levels at commodity like pricing. Outstanding Energy Efficiency 2X to 4X the energy efficiency of previous generations save costs and enable new capabilities within the same energy envelope Easy to purchase and deploy Express and Solution Edition configurations simplify acquisition and deployment with popular ISV application solutions Workload-optimizing capabilities improve performance, utilization and efficiency Whether you run one application or up to 160 on a single system, get maximum ROI with higher utilization and workload performance Choice of 1 or 2 socket configurations with UNIX, i or Linux Over 15,000 available applications to meet your business requirement with choice in performance and expandability without compromises in scalability, utilization or efficiency. The introduction of these new POWER7 based servers include several new innovative technologies that provide the flexibility to maximize performance based on client workloads and computing needs. In addition to the 6-core or 8-core POWER7 processors, both the Power 750 Express and the Power 755 are Energy Star qualified servers meeting the rigorous energy efficiency guidelines set by the EPA and the U.S. Department of Energy. Workload optimization capabilities can help clients get the most value from the Power 750 Express server. For example, Intelligent Energy optimization enables the POWER7 processor to operate at a higher frequency if environmental conditions permit, for increased performance and performance per watt; or alternatively operate at a reduced frequency for significant energy savings. Thread optimization technology enables workload optimization by selecting the most suitable threading mode for the application. Single Thread or Simultaneous Multi Thread-2 or 4 modes can be dynamically selected. One partition may be running a batch job in SMT1 mode while another partition could be running a highly threaded application in SMT 2 0r 4 mode. Consequently, thread optimization can enable optimal application performance. In addition, If available processors are underutilized POWER7 processors can intelligently access their available cache to deliver improved performance for those processors that can use it. With POWER7 based servers we also introduce Active Memory Expansion which can make the physical memory on the system appear to the application as if it were significantly larger than it actually is. Active Memory Expansion can provide additional memory capability to applications transparently and enable more partitions to be run on a server or enabling a partition to do significantly more work by having access to more memory. These capabilities combined with the Power 750 Express servers support for up to 320 virtual machines by year end enable clients to run even more workloads and increase utilization. These capabilities deliver a no comprise approach to maximize server utilization and run applications in the way they run best. Finally, Our Express offerings continue to focus on ease of ownership for clients by offering customer installable, popular configurations that are easy to buy and maintain with dramatic improvements in energy efficiency. 7

10 DB2 exploitation of IBM POWER Systems IBM DB2 is fully optimized for POWER architecture Deep integration with AIX APIs for superior performance Multi-year TPC-C, TPC-H and SAP benchmark leadership Autonomic exploitation of POWER features such as larger page sizes Enabled and optimized for IBM Virtualization technology - PowerVM Deep enablement of POWER6 and POWER7 hardware features in DB2 Decimal Floating Point, Storage Keys

11 Overview of latest Hardware architecture and trends Multiple cores in a chip Dual Core, Quad Core, Hexa Core, Octi core, etc Multiple hardware threads per physical CPU POWER Simultaneous Multi threading (SMT) NUMA (Non Uniform Memory Access) topology Architecture that hardware designers have adopted for constructing large systems to improve scalability over symmetric multiprocessing (SMP) Latency of all memory accesses are NOT equal Remote memory accesses are very expensive and induce stalls Smaller L2/L3 cache Ratio of physical memory available to L2/L3 becoming smaller and smaller Can t fit all data you want in a small L2 Must keep instruction foot print to the minimum requires optimized software HW that uses out-of-order execution limits stalls 11

12 How DB2 addresses the challenges DB2 has been optimized for POWER architecture Intelligence built into DB2 automatically detects architecture and takes appropriate decision DB2 has smarts built in to take maximum advantage of hyper/multi threading Proper distribution of work between hardware threads allows DB2 to efficiently use available CPU to do useful work On POWER architecture, DB2 also uses hardware thread priorities yielding up to 30-35% performance for certain workloads Judicious use of L2 cache prefetch instruction embedded into DB2 to limit cache stalls Careful placement of hot and critical structures along processor cache line boundaries Reduced instruction footprint by use of advanced compiler optimizations and workload profiling DB2 has been optimized for current hardware trends. DB2 internal cache lines are optimized for reduced cache sizes. Prefetching of DB2 instructions before they execute enables us to keep the CPU busy all the time. Threaded architectures allows for many simultaneous activities with lower overhead than a process based solution. 12

13 DB Memory Simplification through threading AIX threading greatly simplifies DB2 s memory model one big flat address space Lower memory footprint Buffer Pool Log Buffer db2wdog User User User db2agent db2agent db2agent db2pcln db2pfchr db2loggw db2loggr db2dlock db2sysc db2cart Containers Control File Logs One of the reasons for the ease of use enhancements with respect to configuration parameters on the previous slide is that in DB2 9.5 the engine is a threaded architecture on UNIX and Linux as well as on Windows. This means that every DB2 process in previous releases is now run as an operating thread within a single DB2 process (db2sysc). The blue rectangle above represents the single DB2 process and the blue ovals within it are all now DB2 threads. The benefit is that DB2 now has one large shared memory address space to which all working threads in DB2 can access. There is no separate agent private memory and database shared memory. Instead, all of the memory is shared (under the database shared memory) and therefore DB2 can now automate the allocation of memory more easily and with a greater impact on the overall throughput of the system by allocating memory where it is needed most.

14 Efficient Logging Logging is the most critical factor in high volume OLTP TPC-C proves that DB2 has a more efficient logger DB2 logged less than ½ that of Oracle and SQL Server DB2 logged 1/8 th the amount of Oracle RAC DB2 9 on POWER = 2.4KB of log per transaction Oracle 11gR2 = 4.9KB of log per transaction Oracle 11gR2 RAC = 19KB of log per transaction SQL Server 2005 = 6.0KB of log per transaction Reduced logging = increased performance In very high volume transactional systems the logger can quickly become the bottleneck. DB2 (and other RDBMSs) can do most of the work a transaction requires completely in memory. However there is one thing that cannot happen in memory. Whenever a transaction performs a COMMIT the information that tells the RDBMS how to redo that transaction (i.e. the log information) must be flushed to disk. In order to achieve very high concurrency and high throughput, it is essential that the logger be as efficient as possible since these I/Os can quickly become the bottleneck (since disk access is significantly slower than memory access). There is a very strong proof point that demonstrates DB2 has a much more efficient logger than our competitors. TPC-C is an industry standard transaction processing benchmark that all major database vendors participate in. Each vendor runs their own benchmarks to try to demonstrate they have the best RDBMS. DB2 comes out on top more often than any other database vendor (but more on that later). One interesting thing to note about TPC-C is that one of the requirements of the benchmark is that you also publish how much log space you consume during the benchmark run. By comparing the log space consumed (and knowing that this standard benchmark requires every vendor to run the exact same transactions over and over again) we can compare the efficiency of the 3 database vendor s loggers. The most current TPC-C results (as of Sept 18, 2010) are shown on this chart.

15 Unique Features of POWER Core Only DB2 Exploits POWER7 on core Decimal Floating Point Unit DB2 is the only DBMS vendor to natively support DECFLOAT data type Performance advantage for retail and finance 40% performance gain in SAP BW Have seen up to 6x faster performance POWER7 Core POWER7 chip has on-chip L2/L3 cache with edram L3 Cache DB2 is cache aware Optimizes power of the core POWER7 Chip DB2 supports the ANSI DECFLOAT data type which provides for the precision of the floating decimal points and the performance of DECIMAL. - on AIX we leverage the hardware implementation for decfloat arithmetic DB2 aligns data structures on cache line boundaries to ensure we do not get false conflicts and also prefetches program data with cache instructions

16 Hardware Memory Protection Exploitation Without Storage Keys DB2 CALL my_unfenced_udf ( ) With Storage Keys DB2 CALL my_unfenced_udf ( ) Client Error returned to CALL statement Agent Bufferpool my_unfenced_udf() BUG Memory Overwrite! X my_unfenced_udf() BUG No Overwrite! This slide shows how storage keys can prevent a memory overwrite. This slide is best viewed in screen show mode. On the left, an unfenced UDF has access to DB2 shared memory space which could result in a buffer pool corruption if the UDF has a bug in it. However on the right when the bug tries to corrupt the bufferpool when storage keys are turned on, the UDF is prevented from doing so and will abort the transaction.

17 Simplicity Tuning knobs AIX 6L removes many tuning knobs required previously vmm, aioservers DB2 transparently uses 64K OS pages where available DB2 automatically configures Initial configuration based on machine size Ongoing tuning with STMM Dynamic reconfiguration of DB2 to react to added or removed resources in an On Demand manner in virtualized environments

19 DB2 purescale Unlimited Capacity Buy only what you need, add capacity as your needs grow Application Transparency Avoid the risk and cost of application changes Continuous Availability Deliver uninterrupted access to your data with consistent performance Learning from the undisputed Gold Standard... System z DB2 purescale is an optional DB2 feature that reduces the risk and cost of business growth by providing unlimited capacity, continuous availability, and application transparency. Unlimited Capacity You can grow the system as you need to up to 128 Members in the cluster. Application Transparency Avoid the risk and cost of application changes. As you grow the system, you do not need to make the application cluster aware in order to get good scalability. Continuous Availability DB2 purescale is designed for systems that need continuous availability. If a member or the PowerHA purescale server fails, transaction continue to process uninterrupted. DB2 purescale uses the same architecture as the undisputed gold standard of reliability System Z. Businesses trust this architecture to run their most critical systems. We ll be walking through how DB2 purescale can help your business and how DB2 purescale works.

20 The Key to Scalability and High Availability Efficient Centralized Locking and Caching As the cluster grows, DB2 maintains one place to go for locking information and shared pages Optimized for very high speed access DB2 purescale uses Remote Direct Memory Access (RDMA) to communicate with the powerha purescale server No IP socket calls, no interrupts, no context switching Results Near Linear Scalability to large numbers of servers Constant awareness of what each member is doing If one member fails, no need to block I/O from other members Recovery runs at memory speeds Member 1 Member 2 CF Group Buffer Pool Group Lock Manager Member 3 PowerHA purescale Now for the first time, the capabilities found in the coupling facility are available on a non-mainframe platform. By providing centralized locking and centralized caching, DB2 purescale delivers a scale-out active-active solution that is second to none. DB2 purescale is designed for modern hardware capabilities, including InfiniBand and Remote Direct Memory Access (RDMA), which will be discussed in more detail in the next section. Centralized locking and caching are provided by the PowerHA purescale cluster acceleration facility (henceforth referred to as the CF) in DB2 purescale. By placing hot data in a centralized buffer pool, and by accessing that data without costly IP socket calls the scalability of the solution is greatly improved. As well, by centralizing lock information, the CF is aware at all times what data pages are in process of being updated by any member in the cluster. As such, if any member fails, the CF holds all the page locks from the failed member to speed recovery processing. There is no need to lock out other nodes from accessing the shared disk during recovery processing as is the case with Oracle (more on that later).

21 DB2 Advantages for Mixed Workloads Many OLTP workloads already have a large batch component DB2 already has strong customer proof points Large Chinese Financal with OLTP/Batch on a 40TB system Large global ERP system with 24TB Add in purescale to allow Batch on one node and transactional on the other nodes in the cluster Transaction Processing Member 1 Transaction Processing Member 2 Batch and Utility Member 3 Mixed workloads are characterized by highly intensive transaction processing workloads mixed with either complex query (as in the case of SAP and other ERPs) or large batch components (as it typically the case with roll-your-own OLTP systems). DB2 has a very strong presence in this type of workload with many large customer references. Add to this the fact that purescale can be used to add separate resources so that you can dedicate some processing power to batch or complex query workloads and you can build out a solution to deliver the best of both worlds.

22 DB2 on Power Advantages for Consolidation Consolidation needs: Effective workload management DB2 WLM integrated with AIX WLM delivers most effective resource utilization across the entire server Oracle workload management does not share across instances and cannot be used with AIX WLM Dynamic resource allocation DB2 self tuning memory can immediately leverage additional resources or scale back if resources needed elsewhere Oracle can only share resources within a single instance Ultra high reliability purescale delivers higher availability than Oracle RAC Power Systems 3x-4x more reliable than x86 servers Simplified problem determination Exadata has separate storage servers and database servers making problem determination even more difficult Scalability (scale out and scale up) transparently to the application There are a number of factors that are required in order to truly deliver on the cost savings message of consolidation. This chart talks about the requirements for a consolidated environment and how DB2 delivers superior capabilities in these areas.

23 Consolidation for Cost Savings on DB2 purescale Start with the server sizes customized to fit your application Don t overbuy servers Flexibility in server size and cores per server Flexibility in amount of storage allocated Standby CF 2 cores Payroll Member 1 4 cores Primary CF 2 cores Payroll Member 2 4 cores Power core Power core DB2 purescale can be customized for a given workload. There is no need to buy 28TB of storage for a database that is only 1TB in size (or less). Similarly the building blocks are more granular than ¼ rack, ½ rack, full rack increments. Start with what you need and grow as you need to.

24 Consolidation for Cost Savings on DB2 purescale Grow with next generation servers Scale up on existing servers or out onto new servers Mix and match servers to fit your application profile Leverage resources across the cluster (utilize the strengths of PowerVM) Primary CF 2 cores Payroll Member 1 Standby CF 2 cores Payroll Member 2 HR Member 1 6 cores Primary CF HR Member 2 6 cores Standby CF 4 cores 4 cores 2 cores 2 cores Power core Power core Power core 750 supports up to 64 cores Power core DB2 purescale also allows for a mix of hardware. For example you could have your HR system and your Payroll system spread across different hardware generations of different sizes.

25 Consolidation for Cost Savings on DB2 purescale Consolidate onto the number of servers that make sense for your business Purchase the most cost effective servers not one size fits all Standby CF 2 cores Primary CF 2 cores Payroll Member 1 Primary CF 2 cores Standby CF 2 cores Payroll Member 2 ERP Member 2 8 cores HR Member 1 6 cores Primary CF ERP Member 1 8 cores HR Member 2 6 cores Standby CF 4 cores 4 cores 2 cores 2 cores Power core Power core Power core 750 supports up to 64 cores Power core As you need to grow you can grow out or scale up depending on your needs. Chose the configuration that gives you the best price/performance and the simplest management configuration.

32 Latest DB2 on Power TPC-C Result Optimized for performance = reduced license costs Replace almost 3 cores of Oracle/Sun with DB2/Power DB2 9.7 on 3 64-core Power 780: 10,366,254 tpmc, $1.38 /tpmc, Availability 10/13/2010 Oracle 11g RAC on core Sun T5440; 7,646,487 tpmc, $2.36 /tpmc, Availability 03/19/2010

33 DB2 Outperforms Oracle by 16% in Apples to Apples Comparison Both on exactly the same server (8way 1.9GHz p5 570) DB2 leads in performance by 16% over Oracle DB2 vs Oracle on 8way p570 tpmc % Faster DB2 Oracle Results current as of May 10,2010 Check for latest results DB2 on 8way p5 570: 429,899 tpmc, $4.99 /tpmc, Availability 09/30/2004 Oracle on 8way p5 570; 371,044 tpmc, $5.26 /tpmc, Availability 09/30/2004 It is not very often that you get an Apples to Apples comparison where two database vendors run their benchmarks on the exact same hardware. This result is dated (using DB2 v8 against Oracle 10g) however it shows that on exactly the same hardware, DB2 delivered 16% better performance than Oracle. In fact you would need 10 CPUs of Oracle to match the performance of 8 CPUs of DB2 on this class of server.

34 Longevity in Transaction Processing Performance Benchmarks are often a game of leapfrog However, DB2 has demonstrated sustained superiority over competitors Results as of Sept 23, 2010 This chart represents days of leadership for TPC-C Since Jan 1, Clearly DB2 is the dominant performance leader having lead Oracle and Microsoft longer than both of them combined.

35 Performance Leadership in SAP with DB2 and Power The clear leader in SAP Performance Joint design and development leads to better products DB2 on 32 core IBM Power 595 DB2 on 4 core IBM Power 570 Oracle on 64 core HP Superdome Oracle on Sun Won t Say Oracle on 16 core Sun E6900 DB2 on 4 core IBM Power 570 Oracle on 16 core Sun E6900 Day Processing Night Processing Similarly DB2 on IBM Power dominates Oracle on Sun in SAP benchmarks. The classic 3-tier SAP SD benchmark has long been the metric for high end SAP benchmark performance as it simulates a real world customer environment (where the database runs on its own server and the SAP application servers run on a set of middle tier servers). In this benchmark once again DB2 on a 32 core IBM Power 595 outperforms Oracle on a 64 core HP Superdome by a wide margin. Again Oracle on Sun is a no show in this benchmark. Similarly SAP has a transaction banking benchmark in which DB2 on just 4 cores of IBM Power 570 outperform Oracle on a 16 core Sun E6900 by a wide margin. The 32-core IBM eserver p5 595 three-tier SAP SD Standard Application Benchmark result (168,300 benchmark users, 1.95 second average response time, 16,896,670 fully processed line items per hour, 50,690,000 dialog steps/hour) on SAP R/3 Enterprise Release 4.70 solution. SAP Certification number The 64-core HP Integrity Superdome three-tier SAP SD Standard Application Benchmark result (100,000 benchmark users, 1.75 second average response time, 10,210,330 fully processed line items per hour, 30,631,000 dialog steps/hour) on SAP R/3 Enterprise Release 4.70 solution. SAP Certification number SAP and all other SAP product and service names mentioned herein are trademarks or registered trademarks of SAP AG in Germany and several other countries around the world.

36 Longevity in Data Warehouse Performance First to publish 10TB TPC-H Leader in 10TB TPC-H Only vendor to hold both 10TB TPC-H and leading TPC-C at the same time Results as of Sept 23, 2010 DB2 is also the database performance leader in TPC-H. Having led longer than all other vendors combined at the 10TB scale factor (common database size for many data warehouse customers).

37 Summary DB2 Performance on IBM Power Higher Performance = Lower Costs DB2 High Availability with IBM Power More Reliable DB2 and IBM Power Lowers Total Cost of Ownership Deep Technology Innovation Delivers More Value DB2 on POWER7 delivers even more integration and more value to customers The bottom line is, due to the close working relationship that has existed for almost 20 years now within a single company, the combination of DB2 on IBM Power servers is unmatched in terms of performance, availability and lowering overall costs.
