SAP HANA HA and DR

Scenario 1: Single-AZ SAP HANA HA (System Replication in the Synchronization Mode + Preload on + SUSE HAE) and Cross-AZ SAP HANA DR (System Replication in the Asynchronization Mode + Preload on)

Scenarios

Deploy the primary and secondary SAP HANA systems in the same AZ and configure the System Replication function of SAP HANA and the SUSE HAE function to enable automatic switchover and realize HA. In the other AZ, deploy a secondary SAP HANA system and configure Multitier System Replication function to implement cross-AZ DR. This applies to the scenario where a single SAP HANA node is deployed.

Deployment Plan

Figure 1 shows the deployment plan of SAP HANA HA within an AZ and SAP HANA DR across AZs.

Scenario 2: Single-AZ SAP HANA HA (System Replication in the Synchronization Mode + Preload on + SUSE HAE) and Cross-Region SAP HANA DR (System Replication in the Asynchronization Mode + Preload on)

Scenarios

Deploy the primary and secondary SAP HANA systems in the same AZ and configure the System Replication function of SAP HANA and the SUSE HAE function to enable automatic switchover and realize HA. In the other region, deploy a secondary SAP HANA system and configure Multitier System Replication function to implement cross-region DR. This applies to the scenario where a single SAP HANA node is deployed.

Deployment Plan

Figure 2 shows the deployment plan of SAP HANA HA within an AZ and SAP HANA DR across regions.

Scenario 3: Cross-AZ SAP HANA HA (System Replication in the Synchronization Mode + Preload on + SUSE HAE) and Cross-Region SAP HANA DR (System Replication in the Asynchronization Mode + Preload on)

Scenarios

Deploy the primary and secondary SAP HANA systems in different AZs of the same region and configure the System Replication function of SAP HANA and the SUSE HAE function to enable automatic switchover and realize HA across AZs. In the other region, deploy a secondary SAP HANA system and configure Multitier System Replication function to implement cross-region DR. This applies to the scenario where a single SAP HANA node is deployed.

Deployment Plan

Figure 3 shows the deployment plan of SAP HANA HA across AZs and SAP HANA DR across regions.
