When I started building my VMware ESXi server, I did not have a Switch that could handle 10Gbe SFP+. Now that I have a Dell X1052, I figured I would cable up a 10Gbe DAC and get moving. Much to my surprise, I received a link light on the switch, but not on the motherboard.
Digging into the VMware side, I noticed that the 10Gbe NICs are not available, only the 1Gbe NICs.
A quick Google search brought me to a great site for VMware knowledge, tinkertry.com. It appears that the drivers for the 10Gbe are not loaded. So following the directions here, we open the SSH Console and enter the following command.
esxcli software vib install -v https://cdn.tinkertry.com/files/net-ixgbe_4.5.1-1OEM.600.0.0.2494585.vib –no-sig-check
We then reboot our host to get the new VIB to be loaded.
Low and behold on reboot we see the two 10gbe NICs.
