Many companies nowadays still use SAP R/3 for ERP purposes. At the firm I'm working this was also the case. A few months ago the decision was made to migrate to SAP S/4HANA, the latest SAP version equiped with many enhancements and, last but not least, an in-memory database which should mean faster queries and performance!
My job was to provide the technical infrastructure for migration and the SAP S4HANA servers and since it was a hard job for me to find an installation manual for the proper SAP S/4HANA server installation here's my 2 cents.
Requirements:
- Suitable hardware. Best practices and recommendations can be found here and here
- SUSE Linux Enterprise Server for SAP Applications license (this link). You'll need at least one 2-socket license per SAP S/4HANA server
Installation steps:
In my situation the SAP S/4HANA servers must be installed on VMware vSphere 6.7 servers, upgraded to the latest version, so the description is based on that.
- Create a new Virtual Machine with the following specs to start with. At a later stage additional VMware Paravirtual SCSI Controllers and disks will be added for SAP S/4HANA purposes.
- Guest OS: Linux, SUSE Linux Enterprise Server (x64)
- CPU: 8 devided over 2 sockets
- Memory: it depends, in my case it was 256GB
- SCSI Controller: VMware Paravirtual
- Disks:
- 50GB (SCSI 0:0)
- 30GB (SCSI 0:1)
- 30GB (SCSI 0:2)
- Network: VMXNET 3
- Boot the Virtual Machine and mount the downloaded SUSE Linux Enterprise for SAP Applications image.
- Select the correct language, keyboard layout and product to install. For a SAP server choose SUSE Linux Enterprise Server for SAP Applications
