SAP-HANA Architecture

SAP HANA Architecture

What is SAP HANA

SAP Hana is an In-memory column oriented RDBMS developed by SAP-AG.

It is a combination of Hardware and Software which integrates different components i.e. HANA Database, SLT(SAP Landscape Transformation Replication, DXC(Direct Extractor Connection).

SAP HANA Index Server

The most important Server in the architecture is the Index server. The actual data is contained here and the engines that process this data are also present in the index server itself.

SAP HANA Name Server

Stores information about the topology of the SAP HANA System. SAP HANA can also run on multiple hosts. In these cases, the name server knows where each component runs and also knows which data is located on which server.

SAP HANA Pre-processor Server

Whenever a text analysis functionality is called upon by the index server, the pre-processor server answers such requests.

SAP HANA Statistics Server

This collects data about the resource allocation, performance and status of the SAP HANA system. It keeps a regular update on the health check of the HANA appliance.

SAP HANA XS Server / XS Engine

The XS Engine allows external applications to access the data models in the SAP HANA database via XS Engine Clients. It transforms the persistence model in the database into consumption model for external clients to be exposed via HTTP/HTTPS.
