SAP HANA Server Consists of
  1. Index server
  2. Pre processor server

1. SAP HANA Index Server
  • SAP HANA Database Main server is index server. Detail of each server is as below:
  • It's the main SAP HANA database component
  • It contains actual data stores and the engine for processing the data.
  • Index Server processes incoming SQL or MDX statement. (Learn database concepts from SQL server training)
SAP HANA Index server overview
Session and Transaction Manager: Session Component manage sessions and connections for SAP HANA database. Transaction Manager coordinates and control transactions.
SQL and MDX Processor: SQL Processor component queries data and send to them in query processing engine i.e. SQL/SQL Script / R / Calc Engine. MDX Processor queries and manipulates Multidimensional data (e,g. Analytic View in SAP HANA)
SQL / SQL Script / R / Calc Engine: This Component executes SQL / SQL script and calculation data convert in calculation model.
Repository: Repository maintain the versioning of SAP HANA metadata object e.g. (Attribute view, Analytic View, Stored procedure).
Persistence layer: This layer uses in-built feature "Disaster Recovery" of SAP HANA database. Backup is saved in it as save points in the data volume.
2. Processor server
This server is used in Text Analysis and extracts data from a text when the search function is used.
3. Name Server
This Server contains all information about the system landscape. In distributed server, the name server contains information about each running component and location of data on the server. This server contains information about the server on which data exists.
4. Statistic Server
Statistic server is responsible for collecting the data related to status, resource allocation / consumption and performance of SAP HANA system.
5. XS Server
XS Server contains XS Engine. It allows external application and developers to use SAP HANA database via the XS Engine client. The external client application can use HTTP to transmit data via XS engine for HTTP server.
SAP HANA Sizing
Sizing is a term which is used to determine hardware requirement for SAP HANA system, such as RAM, Hard Disk and CPU, etc.
The main important sizing component is the Memory, and the second important sizing component is CPU. The third main component is a disk, but sizing is completely dependent on Memory and CPU.
In SAP HANA implementation, one of the critical tasks is to determine the right size of a server according to business requirement. Learn advanced database concepts from SAP S/4HANA training. SAP HANA DB differs in sizing with normal DBMS in terms of:
  • Main Memory Requirement for SAP HANA (Memory sizing is determined by Metadata and Transaction data in SAP HANA)
  • CPU Requirement for SAP HANA (Forecast CPU is Estimated not accurate).
  • Disk Space Requirement for SAP HANA (Is calculated for data persistence and for logging data)
The Application server CPU and application server memory remain unchanged. For sizing calculation SAP has provided various guidelines and method to calculate correct size. We can use below method:
Sizing using SAP ABAP report.
Sizing using DB Script.
Sizing using Quicksizer Tool.
