3 INTRODUCING SAP HANA Radically simple. Astonishingly fast. HANA processes massive amounts of data and provides access to vital information that business users can act on in real-time. HANA has completely transformed the database industry by combining database, data processing and application platform capabilities in a single in-memory platform. HANA also provides libraries for predictive planning, text processing, spatial and business analytics all on the same architecture. HANA makes it possible for applications and analytics to be rethought without information processing latency, allowing sense-and-response solutions to work on massive quantities of real-time data for immediate answers without building pre-aggregates. Simply put HANA is the platform for building and deploying next generation, real-time applications and analytics. Massive speed SAP and Intel engineers jointly tested the scan speed of a HANA database across a variety of Intel CPU processors. These tests achieved results of 3.19 billion symbol scans per second, per core. Radical efficiency A SAP application development team ran a simulation of productive customer data with a 100 million-line financial accounting data set. Porting the data from a classic database to HANA, eliminated unnecessary index and aggregate tables, enabling operational reporting directly within HANA and reducing the data footprint by a factor of 37. Extreme scale SAP, with its partners, set a new record for the world s largest data warehouse using the HANA platform and SAP IQ software. The data warehouse is 12.1 PB of data four times larger than the prior record. 3

4 Approximately 50% of the data used in the data warehouse is structured and 50% is unstructured, representing today s typically complex data warehouse. The data compression rate is approximately 4 to 1. Lower cost A dual OLTP-OLAP architecture reduces the data footprint, which saves on storage costs. Eliminating the need for data extraction and transfer from OLTP to OLAP saves time and resources. Forrester projects 37% cost savings over four years when migrating to SAP Business Warehouse (BW) powered by HANA in year one, SAP Enterprise Resource Planning (ERP) powered by SAP HANA in year two and using HANA for custom application in year three. Flexibility HANA is an ideal big data analytics platform, capable of efficiently loading and rapidly analysing multiple data types in both structured and unstructured forms. With SAP Data Services traditional sources of structured data, such as pointof-sale transactions and customer records, as well as unstructured sources, such as website logs, social media, and video can be loaded into HANA for seamless modelling and analysis. Choice HANA hardware appliances are ideal for large enterprises and companies that require on-site hosting. Appliances are available from nine industryleading hardware partners. HANA cloud options range from basic, entry-level instances to enterpriseclass managed cloud offerings suitable for running ERP and business-critical applications. Cloud-based deployments are ideal for smaller deployments, start-ups and independent software vendors (ISVs) and for situations where a pay-as-you-go model is preferred over larger capital expenditure. An open platform HANA is an open platform that runs thousands of third-party applications on hardware from nine industry-leading partners. Its cloud offerings are provided by external hosting and management partners on three continents. Independent, third-party application developers and start-ups choose SAP HANA to run their applications and commercialise them via the SAP HANA Marketplace. SAP certification programs help third parties optimise their applications for integration with SAP and sell them to SAP s global customer base. 4

5 However Despite the wonderful attributes of HANA, there is still the small detail of TCO. HANA hardware costs are coming down, but it is still expensive, yet still the view remains that you simply migrate all your data to HANA why not, HANA can handle it? Yes, it can handle it easily, and yes there is compression to consider, however, why would you take data that is of no benefit to your business onto such advanced technology? Removing business complete data will significantly reduce your HANA TCO. This reduction in TCO is the key aim of rightsizing data for HANA. RightSizing BW for HANA Volume Assessment In this RightSizing BW for HANA volume assessment exercise, we will produce a complimentary report on your behalf, which outlines: > Data to take to HANA > Data to move onto cheaper NearLine Storage (remaining accessible) > Data that can be removed completely > What size HANA hardware is recommended Reducing the amount of data can also significantly reduce the amount of time it takes to migrate to HANA. Your RightSizing BW for HANA Volume Assessment This assessment is quick, straightforward and non-invasive, using nonconfidential data supplied by you that allows us to understand the data volume of your BW InfoProviders. To begin your assessment, simply follow the attached instructions and send your results to: RightSizingHANABW@proceedgroup.com. If you encounter problems when following the extraction instructions please contact us. 5

6 Information about your system s InfoProviders A) Information about your system s InfoProviders: (Hints for all database systems) To identify the existing InfoProviders of your BW, we need data extracts of the corresponding tables RSDCUBE, RSDODSO and RSTSODS: 1. For InfoCubes start transaction SE16 for table RSDCUBE. 2. Set the maximum hits to and start the selection in dialog mode (F8). 3. Export the results list: System - List - Save Local File (unconverted). 6

7 Extraction of table information B) Extraction of Table Information B1) Oracle database: SAP transaction DB02 (here for SAP BW 7.x) 1. Start SAP transaction DB Branch to menu section Space - Segments - Detailed Analysis (doubleclick). In the pop-up window, enter the Owner (when known). Select all segments for the analysis using the asterisk (*) in field Segments (see screenshot. 3. Results appear after a while (depending on data volume and system resources). Save the data in an unconverted local file via button Export. Export 7

8 IBM DB2 database (here for SAP BW 7.x) B2) IBM DB2 database (here for SAP BW 7.x) 1. Start SAP transaction DB Branch to menu section Space, Tables and Indexes (double-click). In the pop-up window, select all data/tables via the asterisk (*) and start the analysis (F8). 3. Results appear after a while (depending on data volume and system resources). Save the data in an unconverted text file via button Export. (Unfortunately, we can t provide screenshots for illustration. Process is very similar to the Oracle database on p.7). MAXDB database (here in analogy to SAP ECC 6.0) B3) MAXDB database (here in analogy to SAP ECC 6.0): 1. Start SAP transaction DB Select button Table Size Statistics. Branch to tab Largest Tables. Leave field Total Number of Tables empty to ensure selection of all available tables. If this would lead to an unacceptable runtime, please limit with an appropriate value. Start in dialog with F8. 3. Save the results in an unconverted text file. Export 8

9 Extract table details from AS400 (here in analogy to SAP 6.0) B4) Extract table details from AS400 (here in analogy to SAP ECC 6.0) 1. Start transaction SE16 for table DB4TABLE_STAT. 2. Call menu option: Settings è List Format è Choose Fields. 3. Select fields TABNAME_LONG and TABSIZE. 4. Set maximum hits to and start the selection (F8). 5. Export the results list in a text file: System List è Save Local File (unconverted): 6. Save data of part A) and B) and forward the (zipped) files to us: info@proceedgroup.com. 9
