Availability groups RRS feed

  • Question

  • Hi experts,

    I want to Configure 'Always On'  using multiple instances that are installed on my stand alone desktop.

    Please let me know how this can be done, as I understand that the configuration needs all the instances to be in a single domain and have different IP addressess.

  • Hi Sudhakar,

    No, you can't configure AlwaysOn on multiple INstances on single Server\Desktop.

    Please read the requirements clearly - all the SQL instances should also be part of same Failover Cluster so its quite different from DB Mirroring.

    "Deploying AlwaysOn Availability Groups requires a Windows Server Failover Clustering (WSFC) cluster. Each availability replica of a given availability group must reside on a different node of the same WSFC cluster. The only exception is that while being migrated to another WSFC cluster, an availability group can temporarily straddle two clusters."

    Incase you want to test & wanna play with Always ON, setup a few machines using HyperV or similar Virtualization technique so that you can create a Failover CLuster and configure it.
