It is intended to provide an overview of the various aspects that are most relevant and
important to understand and consider when planning a system landscape which features SAP
HANA.

What is SAP HANA?
SAP HANA Enterprise 1.0 is an in-memory computing appliance that combines
SAP database software with pre-tuned server, storage, and networking hardware from
one of several SAP hardware partners. It is designed to support real-time analytic and
transactional processing.
What are the technical components that make up HANA?
The heart of SAP HANA Enterprise 1.0 is the SAP In-Memory Database 1.0, a massively parallel
processing data store that melds row-based, column-based, and object-based storage techniques.
Other components of SAP HANA Enterprise 1.0 include:
 SAP In-Memory Computing Studio,
 SAP Host Agent 7.2,
 SAPCAR 7.10,
 Sybase Replication Server 15,
 SAP HANA Load Controller 1.00, and,
 SAP Landscape Transformation 1 - SHC for ABA.
SAP HANA Architecture Overview:
The SAP HANA database is developed in C++ and keeps running on SUSE Linux Enterprise
Server. SAP HANA database consists of various servers and the most important component is the
Index Server. SAP HANA database comprises of Index Server, Name Server, Statistics Server,
Preprocessor Server and XS Engine.
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 authenticated sessions
and transactions.
Persistence Layer:
The database persistence layer responsible for durability and atomicity of transactions. It ensures
that the database can be restored to the most committed state after a restart and that transactions are
either totally executed or totally undone.
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.
Session and Transaction Manager:
The Transaction manager coordinates database transactions, and keeps track of running and
closed transactions. When a transaction is committed or rolled back, the transaction manager
informs the involved storage engines about this event so they can execute necessary actions.
SAP HANA Operation
This Technical Operations Manual provides an end-to-end picture of the administration tools
available with SAP HANA and the key tasks that a system administrator needs to perform. Links to the
relevant administration documentation of each of the components included in the SAP HANA solution
are provided for details and step procedures
Migration of SAP Systems to SAP HANA?
SAP HANA in an on-premise landscape. Beginning with an overview of available migration
path options, we provide a general recommendation and further aspects and guidance how to
identify the best procedure for your requirements. Take these aspects into the discussion with your
cross-functional teams and use them as basis for an individual assessment based on the boundary
conditions you are facing.
