QuestionQ50

Design and implement high availability and disaster recovery (HADR)

You have an SAP production environment that uses SAP HANA databases on Azure.

You need to deploy a disaster-recovery solution for the SAP HANA databases. The solution must satisfy the following requirements:

  • Support failover across Azure regions.
  • Minimize data loss if a failover occurs.

What should you deploy?

  • A HANA system replication that uses asynchronous replication
  • B Azure Site Recovery
  • C Always On availability group
  • D HANA system replication that uses synchronous replication
Explanation

For SAP HANA databases on Azure VMs, native SAP HANA system replication is the appropriate replication technology. Across Azure regions, HANA system replication should use asynchronous replication because the latency and distance between regions make synchronous HANA replication unsuitable. This provides a secondary HANA system that can be taken over in the disaster-recovery region, with replication lag determining the potential data loss.
