Does anyone have an implementation of ISVA that is replicated to a Disaster Recovery Center?
Do you know the reference mode for this implementation?

I was looking for a solution that would be near-realtime replication. Could be Active Cluster (production environment) with HotStandby Cluster (Disaster Recovery Center).

Or implemented as a Active-Passive, where the passive would "wakeup" if the active cluster would go down (similar to AIX HACMP behavior)

Or worst case scenario the synchronization by applying a backup from a prod ISVA cluster to the Disaster Recovery center ISVA cluster.

If you have some type of architecture that is working in your environment, it would be great if you could share how you made it work.

Another possible solution would be to create a single cluster with 4 nodes. 2 on the DR center, and the other 2 on the main data center.
This way they could replicate all changes automatically to all nodes.
Perhaps by having 1 master node on each data center, and the others could just be read-only members.

In this solution I am not sure the effect of latency on the replication. Is the replication done synchronously or asynchronously?

Thanks
