Do you mean 4x, or QDR? They refer to different parts of the IB
architecture. 4x refers to the number of lanes for the data to travel
down and QDR refers to the data signalling rate.
It's probably irrelevant for this conversation, but if you are just
learning about IB, It's good to understand that difference.
