Always On with clustered disks

    Hi Experts,

    I am trying to build the 2 node 2 clusters with the AlwaysOn.

    Here isthe landscape.

    2 nodes PROD failover cluster (running once instance)

    2 nodes DR failover cluster (running 2 instances - DR and PRE-PROD)

    Both clusters are in different geographies.

    PRE-PROD can be editable. So out of scope of Always On.

    One instance on PROD -> DR of the other box. [Want to achive thru AlwaysON]

    Now my Question:

    1) Do i need to have all the 4 nodes in same failover cluster group? If yes, then this would become MultiSubnet cluster Or Is there any way those 2 diffrerent failover clusters (one DR and one PROD) can be part of AlwaysOn.

    2) Can i use the clustered disks as in the above landscape for always on?

    Thanks

    Yes, all nodes are required to be members of the same windows cluster. How you network between the two is entirely up to you, you could use VLANs

    The whole point of AO is that the nodes do not require shared storage. Unless you plan on using a failover cluster instance of SQL Server as an AlwaysOn replica, shared storage is not rerquired and probably easier if it's not used.
