Agenda Introduction HANA Dynamic Tiering o Key Features of DT With HANA 2.0 HANA Extension Nodes Data Hub Appendix 2

Introduction Simplified Data Management Introduction Efficient Data Management strategy important for customer. Keep actual data in memory and historical data on disk. Not all data has the same value. Because of cost and performance reasons many customers want to move historical data to a different storage tier. In this session we describe different options to move data to different storage tiers. 3

Data Volume Introduction Data Growth Data growth dilemma Typically only ~20% of company data are operational Strong dependencies between database size and HW costs in SAP HANA Scalability may saturate The data growth challenge Decouple data growth from CPU/memory Analyze your data (value, growth rate) Analyze your applications (data access, SLAs) Evaluate your hardware (limitations, extensibility, scalability) Define your Data Volume Management from the beginning Data Growth Dilemma Data Growth Hardware Costs Add HW Nodes Time 4

HANA Introduction Multi-Temperature Data Management HANA data tiering is the assignment of data to storage classes/media based upon data type, operational usefulness, performance requirements, frequency of access, and security requirements of the data. Hot Store This tier is used to store mission-critical data for real-time processing and real-time analytics. Data is retained in-memory of the SAP HANA database. Warm Store This tier is used to store data with reduced performance SLAs, which is less frequently accessed. Data is stored on a lower cost storage tier, managed as a unified part of the SAP HANA database. Cold Store This tier is used to store voluminous data for sporadic or very limited access. Data is stored on low cost storage tiers, like disk or Hadoop, managed separately from the SAP HANA database, but still accessible at any time. 5

HANA Dynamic Tiering Use cases for DT in HANA solutions SAP HANA native data marts / warehouses or applications Add option to manage HANA memory footprint for native scenarios Evaluate use of DLM tool (from SAP Data Warehousing Foundation) see Documentation Table and data management: responsibility of data mart architect / application developers Verify whether your required advanced functionalities are supported with extended or multistore tables (e.g. predictive, geospatial, text ) SAP HANA SAP BW on HANA makes limited use of dynamic tiering: Dynamic tiering can be used for Write-optimized DSOs and advanced DSOs in the propagation and transformation layers of SAP BW (7.40 SP 8 and above) SAP recommends to use extension nodes for warm data management in BW SAP BW/4HANA currently does not support SAP HANA dynamic tiering SAP Bank Analyzer (OLTP Workload) Financial results for previous years could be sent to DT 12

HANA Dynamic Tiering Architecture HANA Dynamic Tiering Architecture Dynamic Tiering (DT) option adds to SAP HANA a disk-based extended store. Extended Store (ES) with Dynamic Tiering (DT) integrates SAP IQ technology into SAP HANA. It is not an IQ database installation, but SAP HANA Dynamic Tiering component installation. Extended Store (ES) uses persisted indexes to accelerate data access, and loads pages with currently accessed data into a buffer cache in memory. Dynamic Tiering is fully integrated into SAP HANA and appears as one database management system with the extended store as an additional disk-based data store. The Extended Store is managed by a separate server process in the SAP HANA system, the extended store server (ES server). It is running besides the Index server process for the In-Memory component. (See slide after next) The Extended Store is fully integrated into database backup and recovery. Backup and recovery includes the whole database, with tables in the extended store and the in-memory stores. Incremental and differential delta Backups supported for dynamic tiering since HANA 2.0. Since HANA 2.0, two-tier HANA synchronous system replication is integrated with DT node in the landscape. 13

Data and system management with dynamic tiering Data Management State as of HANA 2 SPS 03: Application controlled data aging Multistore tables with time selection partitioning, and extended tables Tool support using DLM Cross-store query optimizer, including Calculation Views Encryption of the dynamic tiering store Not supported at this time: Scale out for larger data volumes Multistore table Backup & Recovery State as of HANA 2 SPS 03: Integrated backup (whole system) Full point-in-time recovery Full, file-based backup Delta backups supported Backint interface implemented Full backup encryption Not supported at this time: Storage snapshots HANA Index server Name server HA/DR State as of HANA 2 SPS 03: Automatic failover Two-tier a/synchronous and three-tier system replication Not supported at this time: Cluster managers Data Center 1 HANA host Primary (active) DT host Data Center 2 Secondary (active/active for HANA data) HANA host DT host Hot_P1 Hot_P2 Warm_P3 Warm_P4 Dynamic tiering XS engine DT table spaces One Data backup Data / Log Data / Log Data / Log Data / Log 21

SAP HANA dynamic tiering Multistore table new for HANA 2.0 Add-on option to SAP HANA Manage data of different temperatures Hot data (always in memory) classical HANA Warm data (disk based data store) Introducing two new types of database table: Extended table disk-based columnar table with all data on disk Multistore table HANA partitioned table with some partitions in memory, and some on disk Extending the SAP HANA database Deep integration Common installation, monitoring, administration Data backup and system replication for high availability Consistent transaction management Transparent query processing & optimization Encryption for data security Target scenarios Data warehousing, analytical applications SAP HANA Database In-memory-store Extended store Column table T_C Multistore table T_M Partition 1 Partition 2 Partition 3 Extended table T_E 22

Heterogeneous multistore table partition by range on two columns New for HANA 2.0 Flexible partitioning: first-level partitions may have different second-level partition ranges Supported for HANA column tables as well Partitioning columns do NOT need to be part of primary key The first level partition may reside in either default or extended storage (second-level resides in the same store as first-level) Only range-subrange partitioning is supported Example (simplified syntax): CREATE COLUMN TABLE (P INT, S INT, ) PARTITION BY RANGE (P) PARTITION P_1 USING DEFAULT STORAGE SUBPARTITION BY RANGE (S) (S_A, S_B, S_C) PARTITION P_2 USING DEFAULT STORAGE SUBPARTITION BY RANGE (S) (S_D, S_E) PARTITION P_3 USING EXTENDED STORAGE SUBPARTITION BY RANGE (S) (S_F) PARTITION P_4 USING EXTENDED STORAGE SUBPARTITION BY RANGE (S) (S_G, S_H) PARTITION P_5 USING EXTENDED STORAGE You can specify that some partitions are read-only by specifying the INSERT ON/OFF clause Memory P_1 P_2 The PRIMARY KEY UPDATE clause specifies whether you can update primary key columns S_A S_B S_C S_D S_E Useful for tables that don t have evenly distributed data, and have empty partitions. Disk P_3 P_4 P_5 HANA supports only 16000 partitions in a table S_F S_G S_H 23

Dynamic tiering to HANA shipping optimization Compressed ITAB (New for HANA 2.0) ID Name Brand Mnfctr Price P1 Prod1 XYZ ABC 10.99 Dynamic tiering sends dictionary compressed result as a BLOB, instead of sending uncompressed results row by row. P2 Prod2 XYZ ABC 15.50 P3 Prod3 AAA ABC 12.00 P4 Prod4 BBB ABC 25.00 P5 Prod5 CCC JKL 19.99 Big advantage when results are returned from tables that are highly compressed in dynamic tiering. HANA keeps the data result compressed in memory, and calls functions to acquire the values from the compressed ITAB. Allows much larger result transfer which was not possible before due to memory usage. Advantages 2-3X faster than SP02 HANA P6 Prod6 AAA JKL 5.00 P7 Prod7 BBB JKL 8.99 SP02: 7 rows, 7*10 + 5*7 + 3*7 +3 *7 + 7*8 = 203 bytes ID Name Brand Mnfctr Price P1 P2 P3 P4 P5 P6 P7 Prod1 Prod2 Prod3 Prod4 Prod5 Prod6 Prod7 XYZ AAA BBB 1 1 2 3 2 2 3 ABC JKL 1 1 1 1 2 2 2 10.99 15.50 12.00 25.00 19.99 5.00 8.99 DT 2-5X memory saving SP03: 1 rows, 7*2 + 5*7 + 3*3 +7 +3 *3 +7 + 7*8 = 137 bytes 24

Intermediate result caching Performance optimization for cross-store join operations (New for HANA 2.0) HANA DYNAMIC TIERING Cross-store query optimization: Now turned on by default DT will pull data from in-memory HANA tables during cross-store JOIN operation, and cached Cache can be re-used by subsequent query requests if subset of columns and predicates are subsumed by cached query. Configuration parameters allow users to control cache size and usage by individual result sets Use of cache will be visible in esserver trace files, and also IQ query plan PRODUCTS table in memory ID Name Brand Mnfctr Price P1 Prod1 XYZ ABC 10.99 P2 Prod2 XYZ ABC 15.50 P3 Prod3 AAA ABC 12.00 P4 Prod4 BBB ABC 25.00 P5 Prod5 CCC JKL 19.99 P6 Prod6 AAA JKL 5.00 P7 Prod7 BBB JKL 8.99 Query 1 SELECT P.Name, P.Brand, P.Mnfctr, P.Price, O.Customer, O.Date Query 1 pulls data from HANA FROM PRODUCTS P, ORDERS O WHERE P.ID = O.Product and P.Mnfctr = ABC Query 2 SELECT Query 2 uses result cache P.Name, P.Brand, O.Customer, O.Date FROM PRODUCTS P, ORDERS O WHERE P.ID = O.Product AND P.Brand = XYX AND P.Mnfctr = ABC ORDERS table on disk ID Customer Date Product Quantity O1 C1 1/1/2017 P1 3 O2 C1 1/1/2017 P2 2 O3 C2 1/1/2017 P3 5 Result cache ID Name Brand Mnfctr Price P1 Prod1 XYZ ABC 10.99 P2 Prod2 XYZ ABC 15.50 P3 Prod3 AAA ABC 12.00 P4 Prod4 BBB ABC 25.00 25

HANA dynamic tiering security features Encryption capabilities (New for HANA 2.0) The dynamic tiering store may be encrypted, similar to the SAP HANA store Dynamic tiering store uses strong AES encryption with 256-bit page encryption key Dynamic tiering uses the same data volume encryption root key as SAP HANA SAP HANA and dynamic tiering stores have their own database page encryption keys Backup encryption: Dynamic tiering full backup may be encrypted Dynamic tiering incremental and log backups have the same encryption state as the HANA database HANA Server HANA Server Secure Store in File System (SSFS) SAP HANA System HANA Server Storage subsystem Encrypted hot data DT server DT server Encrypted warm data 26

HANA dynamic tiering supports full array of backup capabilities Full and delta backups with point in time recovery (New for HANA 2.0) HANA dynamic tiering supports: Full data backup Delta backups: Differential backup (delta since last full backup Incremental backup (delta since last delta backup) BACKINT with a single database setup (interface to third party backup tools) Redo log backups Recovery of a full data backup with no log or delta backups Recovery to point in time using full, delta and log backups ( latest time uses log area, too) Backup and recovery using either HANA Studio or HANA Cockpit HANA dynamic tiering does not yet support: Storage snapshots 27

HANA system replication (HSR) with dynamic tiering Two-tier asynchronous and three-tier replication (New for HANA 2.0) Data Center 1 Data Center 2 Two-tier a/synchronous and three-tier replication supported Delta store (RLV) may be enabled on primary only for 2- tier synchronous HANA Server data / log Primary DT Server data_es / log_es A/Synchronous log shipping INITIAL full data shipping HANA Server data / log Secondary DT Server data_es / log_es Supports logreplay and logreplay_readaccess operation modes only Active/active is supported on secondary site, but dynamic tiering data will be excluded from query results (operation: logreplay_readaccess) Data Center 1 HANA Server data / log Primary DT Server data_es / log_es Synchronous log shipping INITIAL full data shipping Data Center 2 - HA HANA Server data / log Secondary DT Server data_es / log_es Asynchronous log shipping INITIAL full data shipping Data Center 3 - DR HANA Server data / log Tertiary DT Server data_es / log_es Dynamic tiering may be added to an already replicating HANA system without disrupting replication Supports arbitrary number of tenants configured with DT New registration of secondary site requires full data shipping for DT. HANA can use backup or snapshots for optimized initialization of memory store. DT now supports delta synchronization of failback site Cluster managers not yet supported Takeover of a non-primary site causes DT server to be restarted no hot standby Optional asynchronous restart available (HANA does not need to wait for DT restart during takeover) Does not support near-zero downtime (NZDT) upgrade Proxy monitoring views can see HANA memory store only, not DT 28

Dynamic tiering support on cloud and virtualized environments The machines of a HANA system must be running on either all bare metal machines, or all virtual machines. No mixed mode allowed at this time. Virtualization support of dynamic tiering: Internal quality assurance of dynamic tiering is performed on VMWare and OpenStack virtual machines Dynamic tiering is running in HEC on virtual machines running XEN hypervisor Public cloud support (dynamic tiering must run on separate machine from SAP HANA): Dynamic tiering is supported on Amazon Web Services Dynamic tiering will announce support for MS Azure in Q2 2018 SAP Note and blogs: https://launchpad.support.sap.com/#/notes/0002555629 https://blogs.sap.com/2018/01/02/sap-hana-dynamictiering-now-supported-on-the-amazon-aws-cloud/ https://aws.amazon.com/blogs/awsforsap/sap-hanadynamic-tiering-now-validated-and-supported-on-the-awscloud/ 29

Additional Info On Extension Nodes

Table data Extension Nodes Deployment Options Extension Nodes Deployment Option 1: Simple Simple deployment option (with up to 100% table footprint): n TB 0.5 * n TB RAM size Working memory log data Legend master worker standby Extension Table data log data log data shared log data log data log data FC Storage NAS Storage (NFS) Minimal re-configuration required, as extension node has same hardware as other slave nodes (size of CPU, RAM, Storage). Extension node has relaxed static memory and dynamic working memory ratio requirement (compare with 1:1 ratio of master/slave nodes). Maximum size of table data distributed on Extension node is ntb (assume extension node has ntb RAM) (e.g. 2 TB extension node 2 TB table footprint) Enablement steps: model warm data, and redistribute data. Generally released since the Datacenter Service Point (DSP) of HANA SPS12. 46

Table data Extension Nodes Deployment Options Extension Nodes Deployment Option 2: Advanced n TB Working memory 0.5 * n TB Table data RAM size Legend master worker standby Extension log log log log log data data data data data shared log data FC Storage NAS Storage (NFS) Advanced deployment option (with up to 200% table footprint): Extension node has same RAM size as other slave nodes; But need to re-configure storage and I/O level (hardware vendor dependent). Extension node has relaxed static memory and dynamic working memory ratio requirement (compare with 1:1 ratio of master/slave nodes). Maximum size of table data distributed on Extension node is 2*nTB (assume extension node has ntb RAM, and not all the tables are loaded into memory). (e.g. 2 TB extension node 4 TB table footprint) Enablement steps: model warm data, and redistribute data. Generally released since the Datacenter Service Point (DSP) of HANA SP12. 47

Extension Nodes Deployment Options Hardware Configurations for Option 1 + 2: Since SAP HANA Extension Node setups with Option 1 and Option 2 use standard HANA HW configurations ALL hardware partners have matching offerings (the configuration of an SAP HANA Extension Node is then done following the guidance in SAP Note 2343647/SAP Note 2415279). Some partners may have offerings that go beyond this with special configurations please check this with your hardware contacts. 48
