This blog post will give quick overview for S/4HANA 1909 Greenfield Implementation.
This Roadmap is intended for SAP BASIS team in an implementation project for SAP S/4HANA on premise. This Roadmap is comprised of different Phases and provide high-level details for each phase.
Phases include -
In the SAP Architecture phase, define overall designing for SAP S/4HANA system. This based on different factors such as - on-premise / hyperscaler (AWS, Azure), OS version (RHEL, SUSE), HANA replication strategy (based on RPO/RTO requirement), backup-strategy.
Here in this example, SAP is deployed on on-premise data center, operating system RHEL 8.1 with PACEMAKER (for ASCS and HANA), HANA replication strategy SYNCMEM.
In the Maintenance Planner phase, create stack.xml file by selecting appropriate software components and download all required components.
In the Installation Preparation phase, perform all pre-requisites for installations.
Consider following pointers -
Following settings are applicable for HANA database -
For detailed steps, please refer SAP note - 2777782 - SAP HANA DB: Recommended OS Settings for RHEL 8
During the installation, the installer

SAP Architecture
In the SAP Architecture phase, define overall designing for SAP S/4HANA system. This based on different factors such as - on-premise / hyperscaler (AWS, Azure), OS version (RHEL, SUSE), HANA replication strategy (based on RPO/RTO requirement), backup-strategy.
Here in this example, SAP is deployed on on-premise data center, operating system RHEL 8.1 with PACEMAKER (for ASCS and HANA), HANA replication strategy SYNCMEM.
Maintenance Planner
In the Maintenance Planner phase, create stack.xml file by selecting appropriate software components and download all required components.
- Login into SAP marketplace
- Select maintenance planner
- Select the Fiori tile Plan for SAP S/4HANA
- Select Install a new SAP S/4HANA
- Then enter SID = S4H ; select Target Version = SAP S/4HANA 1909 ; Target Stack = 02
- Then select choose Co-deployed with Backend for FIORI. For different FIORI deployment approach check this link
- Then Continue Planning --> select OS/DB dependent files --> and Click on Push to Download Basket .
Installation Preparation
In the Installation Preparation phase, perform all pre-requisites for installations.
Consider following pointers -
- OS recommended settings
- Users ids, group creation
- File system creation, mounting and provide appropriate permission
- Define SID, Instance #
- Download all software
OS recommended settings -
Following settings are applicable for HANA database -
- Disable SELinux
- Configure tuned to use profile "sap-hana"
- Disable ABRT, Core Dumps and kdump
- Turn off auto-numa balancing
- Disable Transparent Hugepages (THP)
- Cluster-On-Die (COD) / sub-NUMA clustering technology (Intel 64 platform only)
- Configure CPU Governor for performance (Intel 64 platform only)
- Configure Energy Performance Bias (EPB, Intel 64 platform only)
- Disable Kernel samepage merging (KSM)
- Increase kernel.pid_max
