H!Fiber 10Gb SFP+ PCI-E Network Card NIC, Compare to Intel X520-DA1 (E10G42BTDA), with Intel 82599EN Chip, Single SFP+ Port, PCIe X8, Ethernet LAN Network Adapter Support Windows/Linux/VMware

Confirmed working on windows 11 home. Installed with windows driver 7.13.155.102. Isn’t much more than the intel ones and you get a second sfp port.So far I’m just happy the damn thing is recognized and works with my 10gb sfp rj45.

It fits to synology DS1621+

Works with OpenBSD, FreeBSD, Linux. So for firewall use, it's epic. Just plug it in and poof! The OS just recognizes it. Been using this in a firewall with great results.

Generic X710-DA2 works correctly in both Win 10 and in QNAP NAS. It can be difficult to find generic 10Gb SFP+ cards that are recognized in QNAP TS-x73A or TS-x64 series. I have not tested connections for packets dropped or with fiber adapters, but direct twinax cable operates well.

This is a very fast PCIe card for your ethernet connection. We build custom computers, and many of our clients request that a 10G ethernet card be included with their build. Unfortunately, many are mistaken as to the usability of this board with their present circumstances. Our offices have a 10G network, so all the computers are equipped with 10G cards to communicate with each other at about that speed. Our internet, however, is only 2G, so regardless of the 10G cards in the computers, we only get 2G speed from the internet. You can put this card in your computer, but unless your other computers on your internal network also have 10G cards, you will only communicate at the speed of the slowest computer you are addressing. The same is true with the internet speed. If your internet speed is 1G, that is the speed at which your computer will receive data from the internet regardless of the 10G card in your unit. When internet providers offer 10G service, we will sign up and then have the 10G speed from the internet. As an aside, also realize that all the internet providers limit your upload speed to the internet because they don't want people running a website from your home or office; they fear the traffic you may put on their lines.

Taking one star off, I thought this card would do 2.5 gig - It does not, it is a chipset issue, not a driver issue. Not a problem, put the card into a server on my 10 gig network. Would have loved it to do 2.5 gig - no issues with the card, easy setup and it works. using in Proxmox, Checked on OpenSuse and it worked Speed was right on - though I really didnt check all that much - I dont notice any heat issues on the home server, with a NAS on it.

Good card , works on Windows 11 but you REALLY have to install the driver from the link in QR code (for Windows 11 use setup.exe , not Asus thing or other) because the default driver installed by Windows works, but create a world of problems starting from taking about 10 minutes to apply any change to card setting up to connection disappear sometimes for a minute or two.Also in my case the connection for some reason 1400 on both ports (even the one that have no SFP+ module in it) instead of expected 10G , but since currently this is my only 10G device on the network besides the switch , all others 1GB I do not really care. But it strange.

Windows 10, it worked out of the box. To get it to work on Linux, it took me a little long as it detected the card and showed the interfaces, but I had to dig through the startup log (dmesg) in order to find out that the drivers were not loading. Downloaded the drivers, installed them, and POOF! Working in Linux, too!I don't foresee myself needing to add anymore 10G NICs to any more of my devices, I would definitely consider re-ordering these.iperf3 results[ ID] Interval Transfer Bitrate Retr Cwnd[ 5] 0.00-1.00 sec 1.06 GBytes 9.09 Gbits/sec 53 1.76 MBytes[ 5] 1.00-2.00 sec 1.09 GBytes 9.38 Gbits/sec 9 2.02 MBytes[ 5] 2.00-3.00 sec 1.09 GBytes 9.41 Gbits/sec 32 2.01 MBytes[ 5] 3.00-4.00 sec 1.09 GBytes 9.38 Gbits/sec 2 2.01 MBytes[ 5] 4.00-5.00 sec 1.11 GBytes 9.57 Gbits/sec 44 2.04 MBytes[ 5] 5.00-6.00 sec 1010 MBytes 8.48 Gbits/sec 153 1.99 MBytes[ 5] 6.00-7.00 sec 966 MBytes 8.11 Gbits/sec 131 2.01 MBytes[ 5] 7.00-8.00 sec 1.04 GBytes 8.97 Gbits/sec 15 2.01 MBytes[ 5] 8.00-9.00 sec 1.12 GBytes 9.59 Gbits/sec 66 2.02 MBytes[ 5] 9.00-10.00 sec 1.03 GBytes 8.81 Gbits/sec 163 2.03 MBytes- - - - - - - - - - - - - - - - - - - - - - - - -[ ID] Interval Transfer Bitrate Retr[ 5] 0.00-10.00 sec 10.6 GBytes 9.08 Gbits/sec 668 sender[ 5] 0.00-10.00 sec 10.6 GBytes 9.08 Gbits/sec receiverAs you can see, there is some variation in the speeds, but seeing that this server is now live (I should have saved iperf results before I turned this server loose), but for the most part, I am getting 9+ Gbits per second. Damn impressive.
