S4/HANA next generation ERP to change the dynamics of Business

SAP’s much awaited S4/HANA – a SaaS model that runs on Hana and will change the way companies operate is a very calculative move of SAP.

S/4Hana would eliminate 40 percent of the SAP IT load, which comes with the data exchange between systems like CRM and ERP else BW and ERP, SCM with ERP , by running applications on one system

What this means to IT industry is less hardware and less distributed complex architecture to manage, hence reducing the TOC .

With growing sales over internet and companies going global, big data is causing data complexity. With S/4 HANA this complex system setup will be removed and application and database will be combined and many satellite components will run on a single database. This will reduce redundant data and also resolve the issues of non integrated system structures

The Suite will also  integrates with SAP’s acquisitions like Ariba, SuccessFactors and Concur, which is a huge benefit for customers who are using these products or are planning to use these products of SAP.

Fiori, an easy-to-use graphical user interface (GUI) will be fully utilized for usage with S4/HANA. SAP legacy GUI are age old and with IT dynamics switching to mobile devices and apps SAP Fiori will be a life saver for the next generation for Business.

All new customers who do not use SAP will be a easy and very cost affective to implement S4/HANA , where as existing customers may feel the initial pain due to the migration, licensing and hardware cost involved.

SAP announcement of S4/HANA has made it clear HANA is proved and tested database and ready make a mark in the ERP industry. HANA as a database will be the biggest competitor for Oracle, SQl and DB2. And as pricing of the database gets cheaper huge number of customer will start switching from oracle,Sql,DB2 or any other database to HANA .

By 2025 I predict all SAP customers will be running  HANA  and running multiple components on a single database HANA, And also Non SAP customer will be ditching oracle, sql and other database and be switching to HANA.

PROCESSES IN SAP HANA

PROCESSES IN SAP HANA

Daemon:

              starts all other processes.

keeps all other processes running.

Index Server:

Index server is the main SAP HANA database component

It contains the actual data stores and the engines for processing the data.

The index server processes incoming SQL or MDX statements in the context of authenticated sessions and transactions.
Preprocessor Server:

The index server uses the preprocessor server for analyzing text data and extracting the information on which the text search capabilities are based.
Name Server:

The name server owns the information about the topology of SAP HANA system. In a distributed system, the name server knows where the components are running and which data is located on which server.

Statistic Server:

The statistics server collects information about status, performance and resource consumption from the other servers in the system.. The statistics server also provides a history of measurement data for further analysis.
XS Engine:

XS Engine is an optional component. Using XS Engine clients can connect to SAP HANA database to fetch data via HTTP.

BASIC ARCHITECTURE OF SAP HANA DB

SAP HANA needs at least 128GB of RAM, ideally 1 core can control 16GB of memory, SAP HANA can use 90% of available memory

Sap HANA and SAP HANA Studio should be the same version to avoid issues.

The disk layer has the data volumes and the log volumes and this is a non volatile data storage.

The storage engine helps in data pages and exchange from RAM to disks

Relational engines has the column store and row store the place where it stores data in the RAM

Process or execution engines- process and executes the queries

External interfaces – communicates with HANA Databases, helps in admin data loads and queries.
