Scenarios

This solution allows you to deploy a high availability (HA) environment on Huawei Cloud for SAP S/4HANA with just a few clicks, facilitating digital transformation and providing a highly-reliable and high-performance SAP S/4HANA service architecture on the cloud. It is suitable for the following scenarios:

Enterprises want to quickly deploy SAP S/4HANA at a low cost and demand a highly-reliable and high-performance service architecture.
SAP S/4HANA cloud migration

Architecture

This solution uses Elastic Cloud Server (ECS), Elastic Volume Service (EVS), and Scalable File Service (SFS) to provide a secure and reliable compute, storage, and network environment for SAP S/4HANA, facilitating cloud migration for SAP S/4HANA.

The following figure shows how can you deploy this solution.

Figure 1 Solution architecture

This solution will:

Create one Virtual Private Cloud (VPC) and four subnets. The subnets are used for service/client, internal heartbeat communication, and SFS Turbo file system.
Create two security groups, associate them with ECSs and SFS Turbo file systems, and configure security group rules to protect ECSs.
Create four ECSs and attach two NICs to each ECS. One NIC is used for service data communication, and the other is used for heartbeat communication. Configure the mapping between IP addresses and host names in the hosts file for installing SAP S/4HANA.
Create two virtual IP addresses (VIPs). Bind one VIP to the active and standby SAP HANA database nodes, and the other to the active and standby SAP S/4HANA nodes for HA.
Create 20 EVS disks and use scripts to automatically attach EVS disks to corresponding directories on each ECS based on the file system plan.
Create two SFS Turbo file systems. They will be automatically mounted to the corresponding directories on the ECSs to provide shared file storage.

Advantages

SAP-certified
Huawei Cloud has many SAP certifications for servers, virtualization, SAP HANA, SAP ASE, SAP NetWeaver Application Server, SAP Business One, and more.

Flexible Scaling
Compute and storage resources are provisioned on demand and can be flexibly scaled so that you can have a well control over the costs on running the SAP system.
Easy Deployment
Quick resource provisioning and environment configuration

Notes and Constraints

Before deploying this solution, you have registered an account with access to the target region.

Read the SAP S/4HANA (1809) HA Deployment Best Practice, and this solution automatically performs operations in Software Installation. You need to manually install the software.
If you use the OS SUSE Linux for SAP 15 SP3 provided by Huawei Cloud KooGallery, you need to pay for the according image. This image is used by default. You can also upload a SUSE Linux for SAP OS to create a private image, and enter the image ID for according parameters to complete cloud resource creation.
Currently, SFS Turbo cannot be purchased on a yearly/monthly basis. After it is created, you can manually change the billing mode to yearly/monthly.
