Intel's X520 is the gold standard for 10G NICs. Dual SFP+, supports pretty much any optic or DAC. Runs well in Linux, Windows, BSD. Just make sure you have airflow—they run hot without it. 5

I received very prompt and professional service . We required an OCP3.0 NIC with the x520 chipset due to software requirements, the more readily available x810 chipset NICs would not work in our environment. Linkreal produces a x520 NIC and was a pleasure to do business with. Communication was prompt, service was great, shipping of samples was faster than expected, and most importantly the device works flawlessly. This sample has allowed us to begin evaluation of a new platform, and if the overall platform evaluation is successful, I would not hesitate to order from Linkreal and deploy these units in production 5

Plugged it into my Dell R710 and it worked instantly — no extra drivers needed. Delivers full 10Gb performance on my ESXi VM. Solid piece of hardware. 5

It is a good all around 10Gbs Nic to use on your network. I am still not sold on the jumbo packet camp. I wish I did not have to pick. Maybe one day they will add or change it so I can have 1Gb and 10Gb LinkAgg together with large sized traffic on one Nic and small fast traffic on another Nic. 5

This was excellent. Super clean, works perfectly. I ran a network benchmark on it for ten minutes straight and didn't have even the slightest slowdown. 5
