Hi,

my company had offices in 4 different geographical location and want to build Multi subnet cluster with active / active, to make database available for all location to update centrally. Our intention is to connect cluster database through local active instance to get performance.

1. I like to know is it possible to build active / active multi subnet cluster ?
2. If not what could be the best solution in sql to resolve this ? We Implemented replication but they create data conflict.

regards
sachin

Yes that's possible with AlwaysOn, provided you only require to write to one replica. We are implementing a multi-subnet cluster right now using AlwaysOn. Works great as long as your firewall holes are open and the cluster is configured properly.

Thanks Tara,

Great, I like to know more on storage configuration, are you using storage replication or how you configure storage?

We aren't using shared storage in our AlwaysOn clusters. The only shared resource is a Quorum disk on our 2-node clusters. On our 3-node clusters, we are using node majority so nothing is shared.
