    10Gig on here should work.  I've not had hands-on experience with built-in ones, but I've used add-on cards with X540 to great success.

    Did you inspect /var/adm/messages for any complaints from "ixgbe"?  You're using cat6, which is good.  One silly question --> on the BIOS on the OmniOS box, did you enable PCIe mappings for only the low 32-bits?  That's a longshot, I know, but it may be an issue.

    ALSO, we recently had someone else on-list post about X540, and it turned out they needed a firmware upgrade to get it to work.  Please make sure your BIOS and device firmware are up to date.
