Two 3 node clusters (6 nodes)

I'm in the process of designing a new HA cluster across two locations. The two locations are connected together with multiple dark fibers and I would like to create an robust HA system that can migrate vm's between the locations.

For storage I'm planning on using Ceph as I have experience with it and within Ceph you can define failure domains so when one of the locations fails the whole system can run on the other location.

As I want to have 3 nodes (to have an quorum) on each location with an total of 6 nodes, which is an even number, what is bad. I was wondering if there is something like a failure domain in Proxmox HA/Pacemaker?

Or how do other people have an similar kind of setup? As I said, this is currently all theory and no hardware has been purchased at this moment so I'm open to suggestions.

Thank you in advance!
