For SAP HANA several hardware and software requirements need to be fulfilled.
You can find a complete list of all SAP HANA components and the respective SAP HANA hardware and software requirements in the Product Availability Matrix (PAM)
on the SAP Service Marketplace
Software Requirements: Operating System for SAP HANA
For the SAP HANA system the following operating systems are available:
- SUSE Linux Enterprise Server (SLES) 11
- Red Hat Enterprise Linux (RHEL)
For a new installation, you need to have at least 20 GB RAM
in total just for the software - 15 GB for the basic software plus 5 GB for programs as well as some space for trace files. The additional memory required for data and log volumes varies according to your requirements.
During the update and the installation of the SAP HANA, a hardware check is performed in order to ensure that problems do not arise due to wrong or unsupported hardware configurations in combination with the SAP HANA platform.
The check is a script that is automatically called by the SAP HANA installer and aborts the installation process if it doesn't succeed.
It is not possible to disable the check because SAP HANA is highly optimized for specific hardware configurations which have been designed and tested together with our hardware partners. Outside of these validated configurations, SAP HANA performance and stability cannot be guaranteed.
Hardware Requirements for SAP HANA Network Connection
SAP recommends dedicated server network communication of 10 GBit/s between the SAP HANA landscape and the source system for efficient data replication.
Important directories and their sizes:
The SAP HANA lifecycle management tool hdblcm
requires certain file systems in order to successfully install an SAP HANA system.
The file systems can be defined manually before installation and then specified during installation, or the default file systems can be used. It is important that the file systems listed below are available and have the recommended disk space before starting the hdblcm program.
File System Structure for a Multi-SID Installation
- An SAP HANA system in a production environment must not share any infrastructure with another SAP HANA system.
- Hosts running more than one SAP HANA system (sometimes referred to as multiple-SID installations) can only be used for non-production purposes such as development, quality assurance, or testing.
