WHAT IS SAP HANA?

SAP In-Memory Appliance (SAP HANA)

HANA is a hardware and software combination that integrates a number of SAP

components including the SAP In- Memory Database. SAP HANA is a flexible,

data-source agnostic appliance that allows customers to analyze large volumes

of Enterprise data in real-time. In-memory computing or HANA, has built in

calculation engine for more complex business calculations. With SAP HANA,

SAP can deliver hardware or software (in the cloud) appliance to the

customers. These appliances could be pre-configured to work for certain

business scenarios and the partners (ISVs) could then setup the landscape to

provision the entire solution. It’s based on Linux operation system.

WHAT IS SAP HANA?

Promise of HANA

SAP HANA will bring in-memory, real time analytics to enterprises. Real time analytics would

imply there is no BW (business warehouse) staging required for generating reports. In fact

the way to think about information would be not to think in terms of reports, but in terms of

data analysis, using tools like Business Objects Explorer or ever pivot tables in excel.

Imagine bypassing the need to ask data analysts to prepare specific reports, which can take

hours, if not days to prepare. Imagine if this data (or rather information) is instead available

instantly. And imagine you could do data analysis on the most current data in real time, even

if the data size was millions of transactional records.

This should be possible with HANA. OLTP (online transaction processing) and OLAP (online

analytical processing) will finally come together in real time, which can give significant

advantages to most businesses, especially the ones that have to react very quickly (retail,

energy, emergency response, etc...)

SAP HANA will change the way SAP currently delivers its products

SAP HANA SCENARIOS

There are four kinds of SAP HANA scenarios:

Custom built scenarios

SAP HANA Accelerators

SAP HANA Applications

SAP HANA for existing SAP solutions

SAP IN MEMORY TECHNOLOGY

All data are stored in memory

Maximization of ratio cores: data

High degree of parallelism of operations

High scalability with growing data amounts

High compression rate in memory

Data are stored in columns

Role of disk/storage is reduced to persistency and

recovery

SAP HANA COMBINATION TECHNOLOGY

RDBMS V/S SAP HANA

Today’s database and business software was designed

and optimized for hardware of the 70’s and 80’s

•Single or dual CPU systems •Limited memory space (16-bit and 32-bit) •Data is resident on large capacity slow disk technology •The database is optimized for OLTP applications

SAP HANA ARCHITECTURE

SAP HANA ARCHITECTURE HANA has appliance as the hardware and the database is software.

Data can be brought into HANA with any of the three options

1) Replication services

2) Data services

3) DXC direct extractor connection(leverages the BW extractor)

Once data is into HANA it goes to In-Memory Database

1) Row & column Storage: how the data should be stored in HANA.

These 2 relational engines act as in-memory databases, that is, there primary data persistence is RAM.

2) Calculation and planning Engine: Calculation engine decides how data gets out of HANA. It’s the heart of HANA.

SAP In-Memory Computing Studio:

1) Administration of HANA database.

2) Modeling (business rules applied here in information modeler)

Reporting tools: How data gets out of HANA:

1) SAP business object BI suite(will discuss later)

2) Excel

SYSTEMS MANAGEMENT AND MONITORING

To ensure the smooth running of your SAP HANA systems, it is important to monitor system availability and key performance indicators regularly.The SAP HANA studio includes several tools for monitoring your systems:

System Monitor :

This editor provides you with an overview of all your SAP HANA systems at a glance, including system availability and current resource usage information. From the System Monitor you can drill down into each individual system in the Administration editor.

Monitoring Dashboard:

This Web-browser based view visualizes key aspects of system health and configuration on a single screen with the option to drill down to more detailed views.

Administration :

This editor provides detailed information about resource usage, current alerts, system performance, system configuration, as well as tools for analyzing and troubleshooting issues in your system.

SAP HANA SOFTWARE COMPONENTS

SAP HANA SIZE

SAP HANA LIFECYCLE MANAGEMENT

SAP HANA software includes lifecycle management

procedures for customizing and updating your SAP

HANA platform and for managing SAP HANA content

products and transports. It is provided with each SAP

HANA system.

The services offered by SAP HANA lifecycle

management roughly cover two aspects:

1)Platform lifecycle management to install and

customize the SAP HANA platform

2)Application lifecycle management to manage SAP

HANA content products and content transports

SAP HANA VERSIONS

HANA 1.0 SP2 - Revision 12 - 1.00.12.xxxxx

SP3 - Revision 20 - 1.00.20.xxxxx
