Hi all,
So here's the situation I am facing at the moment.
We just finished our Primary site with all the servers that we need and now we are starting on the DR site. The original plan is to keep both sites connected all the time and have all servers in both sites members of the same active directory forest and domain.
to do that and as part of the original plan we planned on assigning different IP Subnets for both sites so that we can connect them and have domain controllers in both sites replicating AD like one happy family. Also the original plan includes DPM 2012 replication between the 2 sites.
Today, I found out we are required to use the same IP Addresses on both sites for all servers. so it would be something like this:
Primary Site DR Site
Server1 Server2
192.168.1.100IP NAT’ing IP NAT’ing 192.168.1.100
In the primary site server1 knows that server2’s IP Address is 192.168.2.100
In the DR site server 2 knows that server1’s IP Address is 192.168.3.100
When say knows, this really means that we’ll have to use standard primary DNS zones so that we can make static entries for the server names and also disable dynamic registration to avoid the servers registering their actual IP Addresses.
The NAT’ing changes the source address in the header of each packet.
If you ask me this very stupid and I would never choose to do it if it was up to me, but you know how it is.
So here’s what I need help with:
- Does this setup have any chances of success?
- Is there an articulated blog or article that can explain such setup as a good or bad idea?
- What are the potential problems that we should expect to deal with; a side from that fact that it may not actually work at all?
Any help, comments or suggestions are much appreciated and I appreciate you actually taking the time reading my post.
Thanks
