I have a Ctera 800 box and a gigabit cisco sg 300. Cisco is set to auto, flow controll on, LAG on nics and switch ports, no jumbo frames, no port security. The Ctera box is set to auto and LAG. The data gets transfered to another server on the same switch and same server config except for LAG. The transfer rate never gets above 50 Mbps. Any suggestions.
