OVH KS Proxmox HA

I currently have KS-LE B,C,E and 2. So I want to build a Proxmox HA, my purpose is using the one with NVME to provision VM with NVME Storage, and the one with HDD as storage. But how can I get it into a private network, and is it possible for me to use NVMEE at KS-LE-B and HDD at KS-LE-E? or is there any solution for my purpose?

Setup a private VPN in-between your 3 nodes, with for example wireguard.
Storage type doesn't really matter, its just slower for live migration.
Downside you probably limited by the 300Mbit when you want to live migrate your VM's.
But should work.
I thought so, But I think it will need a long process
Nah, setting up proxmox per node maybe 10-15 minutes each.
Then you setup the wireguard vpn, maybe 30-60 minutes total for a beginner.
You find everything on google though if you search.
How will the failover IP assigned to one service work with another?
Probably with heartbeat and triggering an OVH API call.
But that is all theory.
Be aware that running proxmox in cluster mode across datacenters might incur some weird bugs here and there because corosync (the main status sync for the cluster) kinda requires less than 5ms latency, but if this is not a mission critical operation then just try it out and see, have it running myself across several dcs. Only issues I have seen is with migrations and sometimes I have to recreate lxc/vms several times because of corosync failures.
