Just Linked mode will not give you DR solution. Linked mode is used when there are two vcenters and they are linked together to achieve a centralized management. It will show all you Inventory in both the vCenters. The First vcenter will have both its and 2nd vCenters inventory and the Second will have its own and 1st's inventory.
But by using a multi-site SSO the users/permissions will be replicated, and since you have array replication, both of them should work together and give you DR.
