I'm designing an off-site server room for disaster recovery purposes. This off-site space will house duplicates of production servers and backup systems (around 10 Windows systems in total). The backup site and main site LANs will be connected via a WAN link.
My question is: Am I going to be able to keep the IP addresses and server names the same on both networks. Ideally, I'd like the backup site to mirror the main site as much as possible so if there is a problem with the first site, we can fall back to the backup site.
