SAP HANA Admin - Architecture Overview
In SAP HANA system architecture, it contains all the server components that gets installed at the time of installation. Each server has defined set of tasks and different services are run for each server in a SAP HANA distributed environment.
The most important server system and the heart of HANA system is the Index server. This server is responsible for processing SQL/MDX statement using engines in the Index server. It also contains Session and Transaction Manager to keep track of completed and running transactions.
Persistence Layer in the Index server is used for backing up data and transaction of log files.
Following table lists all the key server components in HANA, the corresponding services, and OS process details.
| Server Component Name | Service Name in HANA system | OS Process Name | Component Details |
|---|---|---|---|
| Index Server | Indexserver | hdbindexserver | Responsible for processing SQL statements using SQL/MDX Processors. |
| Name Server | nameserver | hdbnameserver | To maintain topology of SAP HANA system. This is used to manage all the running components and data stored on each component. |
| XS Classic Server | xsengine | hdbxsengine | It can be used to develop and host applications on the top of SAP HANA system. |
| Data Provisioning Server | dpserver | hdbdpserver | To provide SAP HANA smart data access function. |
| Preprocessor | preprocessor | hdbpreprocessor | To analyze the text data and perform search capabilities. |
| Compile Server | Compileserver | hdbcompileserver | This is used to perform compilation of SQL Procedures and doesn’t contain any data. |
| Web Dispatcher | Webdispatcher | hdbwebdispacher | It is used to process HTTP/HTTPS request to HANA XS Engine. |
