There is a hardware limitation because there are only 4 10G MACs available. You cannot have 8 10G ports.

After some google search I cannot get a definite answer regarding the breakout capabilities of this card. I would like to know if the card's 40G ports can be split into 4x10G ports for each 40G port. I see from the documentations that only 4x10, 2x2x10A, 2x2x10B are available but I'm interested in knowing *if this is a software limitation or a a hardware one*. I also see that the total throughput is 40G but this is not a problem for my setup. I need both QSPF ports to be split into 10G ports. So is this possible? ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
