Chapter 2. Installing RHEL 10 for SAP Solutions
Before installing RHEL 10 for SAP Solutions, verify that the system fulfills the requirements of the SAP software, e.g., regarding the RAM size, the swap space, and the storage. For RHEL 10 systems running the SAP HANA database, you must use a RHEL 10 minor release for which the E4S repos are available and which SAP supports. For RHEL 10 systems running the SAP ABAP Platform, you can use any RHEL 10 minor release after SAP has validated SAP ABAP Platform for RHEL 10.
You can install RHEL 10 in interactive mode or you can perform an unattended installation using Kickstart. This document explains how to perform an interactive installation. Please take a look at the product documentation for Red Hat Enterprise Linux 9 for further guidance on how to install RHEL 10.
