Does secondary replicas in AlwaysOn "have" to reside in a Windows cluster servers?, or in a single Windows server

  • Hello:

    I know now that AlwaysOn feature HAS to be installed/configured on a Windows Clustering environment, BUT the secondary replicas, like the Disaster recovery replica residing in a different Data Center HAS to be also in a Windows Clustering environment or can it reside on a SINGLE SQL Server INSTANCE?.

    Appreciate your help.

    Thanks

  • All of the nodes involved in the AlwaysOn group must be part of the same windows cluster

    Standalone SQL Instance works for secondary replica.

    I have implemented for DR setup.

  • Why would you want to put your replica on a stand alone for DR? The AlwaysOn option was built for DR auto failover...hence the name High Availability. I wouldn't recommend using AlwaysOn for with a stand alone instance for a DR site. Nope.

  • In a standard always on config all replicas are stand alone instances. However, the nodes must all be members of the same windows cluster
