1 Efficient and cost-optimized Operation of existing SAP Landscapes with PBS Nearline Storage and DB2 BLU Stefan Hummel Senior DB2 Specialist, IBM Germany

2 Agenda DB2 Introduction DB2 BLU Acceleration DB2 High Availability Backup & Restore More Information

3 Full usage of Unique DB2 Features Faster Query performance For OLTP and OLAP Workload Ease of use STMM, Real time statistics, online reorg High Availability and Disaster Recovery HADR with Cluster Management High Compression Compression rates up to 70-95% Low TCO IBM DB2 NLS data can run on less expensive hardware Customer can reuse his existing hardware, fully virtualized Flexible design - easily adaptable - to customers needs!

4 DB2 BLU History Blink accelerator technology developed by IBM Almaden Research since 2007 Goal of Blink Predictably fast, interactive and ad hoc querying Any query should run in about the same time Without requiring tuning of indexes, materialized views, etc. User need not to change SQL or apps Products offered by IBM based upon Blink: IBM Smart Analytics Optimizer for DB2 for z/os V1.1 GA d Nov Informix Warehouse Accelerator (IWA) GA d March 2011 DB2 BLU (BLink Ultra) - GA d June 2013 SAP support for DB2 BLU GA d December 2013 SAP NetWeaver BW 7.00 and higher 4

5 DB2 BLU: Dynamic and Hybrid In-Memory Technology Based on Blink Technology Predictably fast, interactive and ad hoc querying No need to change SQL or application code Accelerating Reporting Columnar storage, high compression rates Optimal resource usage: CPU, Memory Revolution and Evolution Part of the DB2 kernel Change everything at once, or change incrementally Near unlimited Capacity 1 x DB2 partition: 2k PB (uncompressed: ~8k -20k PB) x DB2 partitions: 2 mio Petabytes (uncompressed ~8-20 Zettabytes)
