Just a note on this thread, we got everything sorted out. There was a little asymmetric routing going on, but the great folks at HGC was very quick in helping us fix this. We had some problem with HGC support at the Hutch before, but they are great and fast now. At the other end in Johannesburg, we have our sister company and Ruhann was great with helping us out. In the end, with the Riverbed we get 1.5MBytes/sec bidirectional for SMB2 (active/active SQL database log shipping). With High-Speed TCP setting, we could get to 7MBytes/sec.
