11. Does Geo-redundancy of GMiD™Box require?

It is not necessary but it can be a benefit. If we want to provide good SLA to the service providers, geo-redundancy is good to have. But it is pretty similar as any other equipment you have in different data centers. You can deploy a GMiD™Box in every DC you have equipment like GGSN/PGW and CGN. It is not necessary to have a centralized GMiD™Box. They can be decentralized but need to have connectivity between instances in order for data replication.
