What are the best Practices Cosideration to Build DR.

Hello,

I am looking for the best practices which should be taken in consideration while designing DR in two site mode and looking for Array-based Replication.

what and how should the DB server replicated, if they are required to, should they be bi-directional Replicated?

How should Network be considered? My SRM will be part of Management cluster, does Management Network will be sufficient for DR activities or separate dedicated VLAN is required?

Thanks

BR,
