Three Tier SAP S/4HANA Stack Deployment using Terraform and Ansible Automation

Description

This automation solution is designed for the deployment of Three Tier SAP S/4HANA Stack using IBM Cloud Schematics or CLI. The SAP solution will be deployed on top of one of the following Operating Systems: Red Hat Enterprise Linux 8.6 for SAP, Red Hat Enterprise Linux 8.4 for SAP, SUSE Linux Enterprise Server 15 SP 4 for SAP, SUSE Linux Enterprise Server 15 SP 3 for SAP in an existing IBM Cloud Gen2 VPC, using an existing bastion host with secure remote SSH access.

The solution is based on Terraform scripts and Ansible playbooks and it is implementing a 'reasonable' set of best practices for SAP hosts configuration.

It contains:

Terraform scripts for the deployment of two servers, in an EXISTING VPC, with Subnet and Security Group. The servers are intended to be used: one for the data base instance and the other for the application instance. The automation has support for the following versions: Terraform >= 1.5.7 and IBM Cloud provider for Terraform >= 1.57.0. Note: The deployment was tested with Terraform 1.6.6
Bash scripts used for the checking of the prerequisites required by SAP servers deployment and for the integration into a single step in IBM Schematics GUI of the server provisioning and the SAP S/4HANA Stack installation.
Ansible scripts to configure the LVM and filesystems, the OS parameters, a Three Tier SAP S/4HANA primary application server and a HANA 2.0 node. Please note that Ansible is started by Terraform and must be available on the same host.

SAP HANA installation media used for this deployment is the default one for SAP HANA, platform edition 2.0 SPS07 available at SAP Support Portal under INSTALLATION AND UPGRADE area and it has to be provided manually in the input parameter file.

SAP S/4HANA installation media used for this deployment is the default one for SAP S/4HANA 2.0 available at SAP Support Portal under INSTALLATION AND UPGRADE area and it has to be provided manually in the input parameter file.

1.2 Server Configuration

The Servers are deployed with one of the following Operating Systems for DB server: Red Hat Enterprise Linux 8.6 for SAP HANA (amd64), Red Hat Enterprise Linux 8.4 for SAP HANA (amd64), Suse Linux Enterprise Server 15 SP 4 for SAP HANA (amd64), Suse Linux Enterprise Server 15 SP 3 for SAP HANA (amd6) and with one of the following Operating Systems for APP server: Red Hat Enterprise Linux 8.6 for SAP Applications (amd64), Red Hat Enterprise Linux 8.4 for SAP Applications (amd64), Suse Enterprise Linux 15 SP4 for SAP Applications (amd64), Suse Enterprise Linux 15 SP3 for SAP Applications (amd64). The SSH keys are configured to allow root user access. The following storage volumes are creating during the provisioning:

HANA DB VSI Disks:

the disk sizes depend on the selected profile, according to [Intel Virtual Server certified profiles on VPC infrSAP HANA DB Server Disks:
the disk sizes depend on the selected profile, according to Intel Virtual Server certified profiles on VPC infrastructure for SAP HANA - Last updated 2023-12-28 and to Bare metal servers certified profiles on VPC infrastructure for SAP HANA - Last updated 2024-05-13

Note: For SAP HANA on a VSI, according to Intel Virtual Server certified profiles on VPC infrastructure for SAP HANA - Last updated 2022-01-28 and to Storage design considerations - Last updated 2024-01-25, LVM will be used for /hana/data, hana/log, /hana/shared and /usr/sap, for all storage profiles, with the following exceptions:

/hana/data and /hana/shared for the following profiles: vx2d-44x616 and vx2d-88x1232
/hana/shared for the following profiles: vx2d-144x2016, vx2d-176x2464, ux2d-36x1008, ux2d-48x1344, ux2d-72x2016, ux2d-100x2800, ux2d-200x5600.

For example, in case of deploying a SAP HANA on a VSI, using the value mx2-16x128 for the VSI profile , the automation will execute the following storage setup:

3 volumes x 500 GB each for <sid>_hana_vg volume group
- the volume group will contain the following logical volumes (created with three stripes):
  - <sid>_hana_data_lv - size 988 GB
  - <sid>_hana_log_lv - size 256 GB
  - <sid>_hana_shared - size 256 GB
1 volume x 50 GB for /usr/sap (volume group: <sid>_usr_sap_vg, logical volume: <sid>_usr_sap_lv)
1 volume x 10 GB for a 2 GB SWAP logical volume (volume group: <sid>_swap_vg, logical volume: <sid>_swap_lv)

In case of deploying a SAP HANA on a Bare Metal Server, using the value bx2d-metal-96x384 for the Bare Metal Server profile, the automation will execute the following storage setup:

4 disks x 2.9 TB each for <sid>_vg0 volume group
- the volume group will contain the following logical volumes (created with raid10, mirror and two stripes):
  - <sid>_hana_log_lv - size 384 GB
  - <sid>_hana_shared - size 384 GB
4 disks x 2.9 TB each for <sid>_vg1 volume group
- the volume group will contain the following logical volumes (created with raid10, mirror and two stripes):
  - <sid>_hana_data_lv - size 100%FREE
1 directory /usr/sap
1 SWAP file of 2 GB /<sid>_swapfile

SAP APPs VSI Disks:

1 disk with 10 IOPS / GB - SWAP (the size depends on the OS profile used, for bx2-4x16 the size will be 48 GB)
1 x 128 GB disk with 10 IOPS / GB - DATA

In order to perform the deployment you can use either the CLI component or the GUI component (Schematics) of the automation solution.

1.3 VPC Configuration

The Security Rules inherited from BASTION deployment are the following:

Allow all traffic in the Security group for private networks.
Allow outbound traffic (ALL for port 53, TCP for ports 80, 443, 8443)
Allow inbound SSH traffic (TCP for port 22) from IBM Schematics Servers.

The passwords for the SAP and HANA systems will be hidden during the schematics apply step and will not be available after the deployment.

Steps to follow

Make sure that you have the required IBM Cloud IAM permissions to create and work with VPC infrastructure and you are assigned the correct permissions to create the workspace in Schematics and deploy resources.
Generate an SSH key. The SSH key is required to access the provisioned VPC virtual server instances via the bastion host. After you have created your SSH key, make sure to upload this SSH key to your IBM Cloud account in the VPC region and resource group where you want to deploy the SAP solution
Create the Schematics workspace:
1. From the IBM Cloud menu select Schematics.
  - Push the Create workspace button.
  - Provide the URL of the Github repository of this solution
  - Select the latest Terraform version.
  - Click on Next button
  - Provide a name, the resources group and location for your workspace
  - Push Next button
  - Review the provided information and then push Create button to create your workspace
2. On the workspace Settings page,
  - In the Input variables section, review the default values for the input variables and provide alternatives if desired.
  - Click Save changes.
From the workspace Settings page, click Generate plan
From the workspace Jobs page, the logs of your Terraform execution plan can be reviewed.
Apply your Terraform template by clicking Apply plan.
Review the logs to ensure that no errors occurred during the provisioning, modification, or deletion process.

In the output of the Schematics Apply Plan the private IP address of the Servers, the hostname of the servers, the VPC and the Activity Tracker instance name will be displayed.
