10G Gigabit Ethernet Converged Network Adapter with Intel X540 Chip, 10Gb NIC Compare to Intel X540-T2 Network Card, Dual RJ45 Copper Ports, PCI Express X8

Bought one of these before and works fine in my server, bought another for the a work station, but this was dead on arrival, tried in two machines (one didnt recognise or see it and other was just red LED didnt do anything) so presumed dead,, sent back got money back once posted return.... will seek another brand.

Purchased this to direct connect my QNAP TVS-882ST3 NAS. My transfer speeds went from 108MBps to over 480 MBps which is close to the limit of the Raid setup. As I add drives I'm sure this card will be able to keep up with the transfer requirements. Note, the card will not speed up your slow network unless you connect it to other 10G cards.

This dual port 10G network card worked like a champ. Installed it in the system, disabled the boot from LAN options (which my system didn't like), but it works great once properly configured. It was NOT hard at all to make the BIOS changes needed OR to install the needed drivers to get it running with the OS.When I need another 2 port 10G network card, I'll go for another one of these!

Plug in play without issue in my Dell R710 Server. Proxmox recognized without having to do anything special. Tested speed hit the expected speeds.

Whatever you do don't get a NIC with a built in fan! The dingy little fan will fail, the card will instantly overheat and your desktop or server will start crash/reboot. A fan on a NIC is an indication of a low quality, low performance / low yield chip. This cards from XZS have a real solid heatsink. Work very well and rock solid stable for our cluster servers.
