I am hoping someone can point me in the right direction here. We are trying to do a proof of concept for a 3 node multi-site cluster on Windows Server 2012 R2 for our SQL Server environment. There will be two different subnets, one in each datacenter. I have come across many articles telling me how to set up the cluster but what I'm having trouble with is the IP address for the cluster.
Does anyone know how I can add the IP from the second datacenter into the cluster? I have come across articles that mention I would have to add an OR dependency for the second IP but I am not sure how to make this IP even appear as an option to add. Am I supposed to have the IP address added to the NIC?
I hope my questions aren't confusing and that I'm conveying them clearly.
