**This is more of a networking question, but I am applying it to FileMaker Server directly
I've got two virtual single machine FM 14 servers under different subnets/buildings that I want to setup to be a hot/cold availability situation. The backup VM is synced from the production every 15 minutes (one of the great reasons to use ZFS filesystem). This server does have a static IP address assigned, but I forgot that I can't use the same IP address under a different subnet. So when the backup server is turned on, it will broadcast to a different IP address. Which isn't ideal, considering it will confuse end users to switch to a different server/IP - I wanted to make this transparent. Unless I move the backup hardware to the same building/subnet, this is going to be an issue that I need help with.
Can I use a DNS round robin technique for this situation? I know it's more for load balancing, but if I change the IP address of the backup to something appropriate to that subnet, then I believe it'll work so the end user only deals with one IP. I do also have to consider WebDirect/IIS and an installed certificate.
If anyone has experience with this and/or can give me some ideas, I would be very grateful!
