Azure site recovery node limit

Does anybody know if there is a limit to the amount of VMs you can replicate to another region using ASR? We currently have a few subscriptions and I am trying to decide if it would be better to have just 1 vault controlling DR, to make it easier with failover plans etc or to have one per subscription which would allow a more granular level of control and less chance of hitting any limits.

How have others set this up when using multiple subscriptions? Is it better to use multiple vaults?

    As far as I know there's no hard limit on how many virtual machines you can replicate to Azure. If your production workload exceeds 650 virtual machines, you should deploy another configuration server.

    I'd use a single Recovery Service Vaults, even for multiple regions, it just makes administration easier, then make sure to configure availability zones for your virtual machines.

    Best regards,
