10Gtek 10Gb PCI-E NIC Network Card, Dual SFP+ Port, with Intel 82599ES Controller, PCI Express Ethernet LAN Adapter Support Windows Server/Linux/VMware, Compare to Intel X520-DA2(E10G42BTDA)

My system already had 10Gb ethernet, but I disliked the heat from the translation between SFP+ and RJ46 so I got this so I could just use a DAC cable between my system and the switch. No issues installing, I just had to download the driver from Intel and install it manually, otherwise it worked pretty quickly without issues. Tested getting full 10-gig speeds through iperf3 no problem. 10Gtek seems to be establishing themselves well in the industry. Great cables, wonderful adapters, and now solid NICs to add to the list of items of theirs I've gotten and used. All work solid and as expected.

I'm using this as a direct attached connection between my Linux box and my Ubiquiti core network switch. It's vastly improved the responsiveness of my network filesystem connections on my macs, and I'm quite happy with it. Zero problems connecting it; I'm on the latest AlmaLinux, and all it needed was configuration after boot. Going from a 1gig ethernet to this was like night and day.

Works great, very little setup needed on my Ubuntu Linux device

I bought 3 of these cards for a couple Synology NAS devices (DS 1618+ and DS 2419+) and my main computer, mainly for faster media transfers and an attempt to edit 4K footage direct from my NAS in real time. The price is significantly more expensive here than buying direct from 10GTek and having it ship from HK and used NICs are apparently very cheap if you look around. I installed the cards in my computer and the DS 1618+ to start with. It was a painless experience and the small form factor bracket was easy to switch on for the Synology. From a networking standpoint there are many ways you can go about it. I opted for a Mikrotik switch with 4 SFP+ ports, which made things a breeze. You can plug directly from one device into another if they both have a 10Gb NIC but you'll need to do some configuration with static IPs. With more than 2 10Gb devices you'll want to get a switch. In terms of cabling, I was only doing short distance networking (7 meters max) so I went for SFP+ DACs. You can also network with a transceiver and RJ45 if you have an existing CAT6 or newer setup, or a multimode fiber, which is good for longer distance networking. The Synology connected to the internet & LAN immediately upon being switched on - completely plug-and-play. My computer wasn't and I don't have a DVD drive so I had to try to find the drivers online. You can essentially treat this as an Intel NIC for most intents and purposes so I went to Intel's website and downloaded the Intel® Ethernet Adapter Complete Driver Pack. That was useful because it not only installed the drivers I needed to be able to connect but also gave me tools to test that the connections were working properly. I've only done one test so far but immediately saw 3-4x transfer speed improvements. Before I was seeing about 113MB/s, bottlenecked by a 1Gb connection. I saw high 300s MB/s during a file copy from my NAS to my SATA SSD, equating to about 3Gb speeds. Your bottleneck will now be the speed of an HDD array or SATA (6Gb). You can achieve even faster speeds with NVMe to NVMe transfers. Overall, definitely happy with this card so far. Seems to be completely plug-and-play for most people.

Easy to install, value for the money, great speed. The machine I have this on is a custom-built desktop running Windows 11, and I had to obtain the driver from Intel. Great product!

Drivers for Windows 11 took an hour to find and required downloading the entire Intel network driver set just to get it installed. Constantly disconnects/reconnects every 5 seconds, so the driver is faulty. Worst of all even when connected via 40gb fiber to a machine across the room it didn't get over 1.2gbps. I'm assuming the Windows driver is at fault, and it may work fine on *nix, but this is just unacceptable. Intel needs to work with Microsoft to get the driver situation fixed so that end users don't have to deal with this kind of crap - it's not like we can troubleshoot things like we can on Linux. We have to endlessly read forums with unpaid volunteers telling us to run chkdsk over and over and over again. Replacing with NON-intel network devices. I'm looking forward to at some point never using Windows or any other Microsoft product ever again. Others who are using this device with Windows - server os or otherwise - verify your actual network throughput using iperf3.

Works fine but the EEPROM is configured for 2 interfaces so the card allocates 8 PCIe lanes even though only 4 are needed.

Great card so far. Works with either fiber sfps, 10G copper sfps or with DAC cables. One caveat with Windows 11: I had to find and install the older Intel x510 drivers for it to be recognized and work. Linux (Pop OS 22.04 LTS) had the drivers and libraries available natively. As far as stability and connectivity is concerned, zero issues so far. A quick Google search found an old Redfit article with a link to the driver pack, so 10 minute fix.

La tarjeta funciona perfectamente a 10 Gb

Excelente producto

funziona su server dell R720

Really impressed with this 10Gtek 10GbE dual port NIC and it's working perfectly in Windows 10. I've installed a couple of 10Gbe SFP+ modules and connected via fiber patch leads to my network and have had absolutely 0 issues. The card is a PCI Express x8 card so make sure you have a suitable slot available to plug it into. For Intel based systems some of your slots may not be directly attached to your CPU and will be limited by your chipset. I've installed the card into an x16 slot which I know will have dedicated PCI lanes and offer the best performance. The card comes in a plain cardboard box with a driver DVD and small form factor back plate. I also highly recommend downloading and installing the latest Intel drivers to leverage the full capabilities of this card (such as VLANs and Teaming etc.)
