If you read the first part of this series you saw that, to enable the intelligent enterprise, first you need the right database back-end capable of supporting the S/4 HANA environment. And SAP HANA was the answer there.
Now, you can migrate to S/4 HANA to get real-time analytics and integration with SRM, SCM, EWM, BI, and ERP. Another benefit is consuming application modules from the cloud while the SAP HANA instance remains on-premises. That means you are not stuck with the large instance and storage expenses in a cloud environment.
This on-premises storage solution is a great benefit we will further discuss below but now, the big question is:
Who can help me migrate to S4/HANA?
And the answer is quick and easy: Lenovo and SUSE!
We can help you ease the transition to S/4 HANA with a more agile infrastructure that enables you to meet customer demands for faster services.
Lenovo has a great history of product reliability and it is in use at SAP’s own datacenter. It also provides end-to-end solution (HW, SW, services and support) and has the architectural know-how encompassing SAP solutions of all sizes on bare-metal, virtualized, or hyper-converged.
The SUSE product Eco-System is the basis of SAP’s own software-defined infrastructure. No other software defined infrastructure engages with SAP the way SUSE does. SUSE also has superior features in HA scenarios, security, and configuration options.
What else, you ask? On-premises storage even if you`re running in the cloud!
As we mentioned earlier, you can consume S4/HANA in the cloud while your SAP HANA instance remains on-premises to save on storage expenses. In addition to the server systems, Lenovo provides several storage configurations for SAP HANA. From integrating into an existing SAN to Lenovo DM storage to a solution that we (SUSE & Lenovo) jointly developed called “Lenovo Storage Solution for SAP HANA powered by SUSE Enterprise Storage” (or DSS-C).
In this particular setup (which was approved by SAP), the four larger server SES nodes are performing multiple duties (OSD nodes, monitors, and gateways nodes). With a smaller server (ThinkSystem SR530-like) as the admin node.
You grow the environment based on requirements:
- If performance is the issue, you buy smaller nodes (like the SR530) and move the gateway servers.
- If capacity is the driving requirement, add more OSD nodes leveraging the same ThinkSystem SR50 platform.
- And, as the cluster grows, move the monitor servers from the OSD nodes and place them on their own platform. A lower-end ThinkSystem SR530 with 16GB of RAM will suffice.
This particular design is for SAP HANA environments. However, with additional nodes and/or gateways that can be tailor-configured, other use cases could be satisfied. For example: SAP backups, or as a data back-end for a data lake to be accessed by SAP Data Hub to name a few.
To the SAP HANA server, the SUSE Enterprise Storage cluster presents two block devices and one shared filesystem. And, installation and configuration services for both the SAP HANA and the SUSE Enterprise Storage cluster are available through Lenovo Professional Services.
