This blog post describes how to install SAP S/4HANA and SAP HANA on IBM Power Systems using Red Hat Ansible Engine as well as Red Hat Ansible Tower. The goal is to automate the installation of SAP S/4HANA and SAP HANA.
Red Hat Ansible
is a powerful command line interface (CLI) automation engine that can automate IT tasks. Red Hat Ansible uses simple YAML syntax to describe a desired configuration, offers secure access to remote systems and integrates with other solutions. For more information about Red Hat Ansible see
Red Hat Ansible documentation
.
Red Hat Ansible Tower
is a web-based console designed to make Red Hat Ansible adaptable for IT teams. Red Hat Ansible Tower helps IT teams to scale automation, roll-out updates, build configurations, organize inventory management, and job scheduling. Red Hat Ansible Tower comes with a web interface and a REST API that can be embedded into other IT processes and tools. The Red Hat Ansible Tower web-based user interface shows overview dashboards about all job exit status, successful and failed playbook runs, status of host inventories, a role-based access control, and a permission system for running playbooks.

The following figure shows two techniques to install SAP software. The first is the installation of SAP software using Red Hat Ansible CLI and the second is the installation of SAP software using Red Hat Ansible Tower. You can use either one of them although depends on your skill set and purpose for use. To install SAP HANA, SAP S/4HANA and SAP NetWeaver, you need to install prerequisites that are specific to Red Hat Enterprise Linux operating system (OS) for target systems like IBM Power Systems; then run SAP installer and SAP product packages. These tasks are automated with Red Hat Ansible CLI or Red Hat Ansible Tower.
Deploying SAP software is requiring SAP admin skill level. Powerful tooling allows to handle
complex deployment scenarios encapsulating this SAP admin skill level in ease-of-use
automation workflows. As an option, Red Hat Ansible can be a choice for this job. You do not
need to program extensive shell scripts because there are already developed open source
packages called Ansible Roles that can be reused from Ansible Galaxy community. Red Hat
Ansible configuration files called playbooks contain instructions for the Red Hat Ansible
Engine. They are written in YAML like key-value pairs hence you do not need to learn a new
programming language. The configuration of required prerequisites and specific
configurations for SAP S/4HANA and SAP HANA has been implemented and published by
the Red Hat Enterprise Linux community.
Red Hat Ansible Tower is a web-based GUI solution to automate the installation of SAP S/4HANA and SAP HANA on IBM Power Systems. Red Hat Ansible Tower offers a graphical dashboard and a navigation menu to show your host status and configuration, to navigate to your job runs and templates, to show your projects and so on. Therefore, using Red Hat Ansible Tower visual user interface (UI) and with a few clicks, you can create a new job template to automate the complete SAP software installation.
Red Hat Ansible runs commands by way of SSH. Therefore, you do not need to install additional software on your server to implement authentication for client hosts. The following table shows many of the features using Red Hat Ansible CLI or Red Hat Ansible Tower:
