According to "http://communities.intel.com/community/wired/blog/2009/06/08/understanding-pci-express-bandwidth"; 8x PCIe should have a bandwidth of 4GB/s. 2 10Gigabit ports is 2.5GB/s. The 82599 only goes up to 8x, so I'd expect that it should be sufficient to handle the full traffic. To any of the Intel guys out there...any ideas? Can an 82599 on an 8x bus handle max line rate with minimum size packets?
