A clustered SAP solution helps protect critical workloads and keep all the solution components up and running if there is a local hardware failure or a data center failure. In that scenario, the clustered SAP solution enables the business to apply critical security patches and other planned maintenance while the system remains available so that users can continue to access their workloads and keep the business going.
Other benefits for customers include:
- Deployment of an SAP HANA HA solution using technology that SAP already provides for SAP HANA. SUSE is the leading provider of operating system distributions that are specific to SAP HANA installations, and SUSE Pacemaker clusters are already part of the SAP operating system distribution. This solution provides guidance that simplifies the configuration and validation of an HA cluster for both database and applications.
- Rapid failover in the event of a failure of the primary SAP HANA database. In that scenario, the failure is automatically detected by the Pacemaker cluster. The cluster shuts down the primary database (if it is still partially running) and activates the secondary database. It also relocates the virtual IP of the tenant database to ensure that all application servers using the database can reconnect to the new primary database. Because all the data is already preloaded in the memory of the new primary database, the failover is very fast.
Note: A focus on SAP HANA is critical because SAP will require all customers to have SAP HANA as their only database to run SAP systems by 2027.
