I have an existing 3 server hyperv cluster using Dell R715 AMD machines.
Now I'm planning out what to do if our server room is damaged in a disaster. The plan is to have a single, fairly powerful, server waiting at another location to restore to. The locations are connected by a 50mbit connection.
If we have some warning, I'd like to migrate the virtual machines between locations. If not, we'll be restoring from off-site backups.
Here's the problem: None of Dell's new servers have AMD processors. Mixing AMD and Intel processors isn't ideal, but it's not in my budget to throw out the AMD servers - and since AMD servers seem to be being phased out, I don't want to be stuck buying older servers.
I know you can't do live migration between AMD and Intel processors. But can you do it while the virtual machine is powered off?
There are a few scenarios where I don't know if I will run into problems:
- Restoring backups from a VM that was running on AMD processors to a host running Intel processors. I doubt this would pose a problem, but you never know.
- Hyper-V replica - can it be done between AMD and Intel servers?
- Live/quick migration of a powered off VM - will the Hyper-V tools allow me to migrate a powered off VM this way, or will it still check processor compatibility? Is my only option to export/import the VM?
