(I know I could use a 1-Gig Enet board, but I would like to | use a 4-port-board to get a 400Mbps bandwidth to my file server) We used to do that with Netware with multiple single-port NICs; it was referred to as load balancing. The server answered get nearest server broadcasts on ports in a round-robin fashion, which caused clients to always TX to those ports. Server TX was sent out whatever port wasn't busy. All ports had to be plugged into a switch for it to work right. How do the Intel NICs that support "teaming" do it? I've always suspected it was something similar, but moved instead from layer 4 to the driver layer. I imagine that FreeBSD would complain if all 4 ports had the same IP address, but that would kind of round-robin accomplish what you're after. It'd also work if the switch and the server both supported multilink trunking. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
