Hello, I am trying to find out what kind of network connectivity is typically required between 2 Active-Active data centers? (Keeping in mind the global traffic management would be required between the 2 sites and all the traffic would typically be coming to Site A first though Akamai).

We currently have a GigE (provided by InterNap) coming to our data center.

Also, has anyone had any experience with SharePlex, which transfers and applies the database changes at Site A to Site B and visa-versa. What kind of network connectivity does it typically require.
