[ovirt-users] Max amount of datacenters per ovirt engine

Hi all, i have a somewhat awkward requirement to deploy datacenters to around 500 satelite locations. Each datacenter will have 1 or 2 hypervisors and if 2 a cluster with glusterfs for shared storage will be deployed. I am expecting to run between 4 and 10 vms per data center. During operations it is expected 20% to 40% of the satelite locations will be down or have a very bad connection to the engine. I will still like to manage these datacenters from ovirt engine. Does anyone have any figures on how many datacenters i can add given what requirements for a single engine and perhaps some best practices for dealing with 'bad' connections between the hypervisors and the engine. Thanks a lot!
