Hi MSFT, One of our customer required to setup SAP HANA Business One in High Availability mode, From Microsoft I only can find below document. What we want to know, whether 2 serves should be sufficient or we need 3 VM to build HA. https://learn.microsoft.com/en-us/azure/sap/workloads/business-one-azure Below is the SAP guide where it says need 3 VMs and one of the server is SAP components and 2 are HANA database in HSR. Can you please provide if any similar document is there Setting_Up_SAP_HANA_Database_High_Availability_for_SAP_Business_One_10.0_for_Automatic_Failover.pdf

    Hi @Sanjay Singh

    According to the SAP HANA high availability for Azure virtual machines documentation, for SAP HANA database high availability, you need to deploy three VMs. One VM is for the SAP HANA system replication (HSR) primary instance, one VM is for the SAP HANA HSR secondary instance, and one VM is for the SAP Business One components.

    So, to answer your question, you need three VMs to build high availability for SAP HANA Business One.

    You can refer to these document https://learn.microsoft.com/en-us/azure/sap/workloads/sap-hana-availability-overview
    https://learn.microsoft.com/en-us/azure/sap/workloads/sap-high-availability-architecture-scenarios Also, these articles provide a good overview of using SAP HANA in Azure:

    It's also a good idea to be familiar with these articles about SAP HANA:

    Beyond being familiar with deploying VMs in Azure, before you define your availability architecture in Azure, we recommend that you read Manage the availability of Windows virtual machines in Azure.

    I hope this helps. Let me know if you have any further questions.
