Introduction
This blog is part of a series to help you pass the
SAP Certified Technology Associate - SAP HANA 2.0 certification exam,
C_HANATEC_13.
For an overview of the exam, see
For the sample questions, see
Topic Areas
There are 10 topic areas and you can expect about 8 questions for each topic.
In this blog, I will discuss the
System Architecture topic.
On the
SAP Training website for C_HANATEC_13, the exam objective for this topic is stated:
Design a system architecture for an SAP HANA implementation
that includes hardware sizing, data persistence,
network requirements and integrates with the existing customer landscape.
Study Material
The study material for this topic comes from training
You can download the index of the guide with the units and lesson objectives from the
SAP Training website.
Unit 4 of HA200 covers the SAP HANA Architecture in 2 lessons with the objectives:
- Explain SAP HANA architecture and technology
- Explain SAP HANA memory management and data persistence
Unit 2 of HA100 covers the SAP HANA Architecture in several lessons of which the 'Understanding the key features of SAP HANA database' lesson is the most important (it is also its objective).
These topics are also addressed in the following SAP HANA guides:
SAP HANA Architecture
Components
A good understanding of the SAP HANA architecture is important for this topic area. Technically, we distinguish different components (server, client, studio, AFL, etc.). From a licensing perspective, these are bundled in editions and options.

SAP HANA 2.0 Editions and Options
Note that feature scope description has changed this year (2018). For the most current state of affairs (at the time of writing), see
There are no questions about which edition contains which component but knowing the different pieces of the platform is certainly relevant.

Deployment Options
You also need to be familiar with the different deployment options: MDC, MCOD, MCOS, etc.
The video tutorial below explains these concepts for SAP HANA 1.0 SPS 12 but this also applies to SAP HANA 2.0.

Under the Hood
Although not in great detail, you might get a question or two about SAP HANA under the hood: its services, the startup process, savepoints (see also the
Backup and Recovery topic), data persistence, and memory management.
For an earlier release, I have recorded a tutorial video about the architecture. This certainly needs an update as XS Advanced and Multitenant Database Containers are not included. However, for the role of the nameserver and indexserver process, the webdispatcher, the client interfaces, etc. not all that much has changed, so if you are new to this topic you still might find it helpful.
The backup and recovery concepts video covers savepoints.

For the documentation, see
Table Management
Additionally, you can several questions related to table management, like column versus row-based tables, column compression and merge operations, table redistribution, data temperature, etc. For this, see
SAP HANA XS Advanced Model (XSA)
You can also expect a couple of questions about XSA, so it is relevant to have some understanding of the architecture and how it compares to XS classic.
There is a lot of documentation and blogs about XSA, so it is to drown in this topic. However. in my exam, there were maybe 2 or 3 questions about XS classic (repository) and only 1 or 2 about XSA so you might want to take this into consideration about how to spend your study time.
If you just want to refresh and test your XS knowledge, try our quiz (where we cover the key concepts):
There is a full playlist about XS Advanced on the SAP HANA Academy:
You do not have to watch all 100+ videos. For this topic, the overview video suffices:
