I want a card with SFP+ ports. I tried a few others and bought this one. So far so good.

This card has good support on almost all common operating systems and has very low power consumption, especially when using a DAC instead of optical fiber.

This worked great, original chip, detected as an Intel chip in my Dell R710 server. Came with both normal and low profile brackets and a decent heatsink. All-in-all a quality card for a good price.

Very quick delivery!

Cannot go wrong with the Intel 82599ES chipset. Very easy installation process. Accessories are comprehensive.

I was looking to upgrade from 1GB ethernet for our server environment. I did a bunch of research on the different options and came to the conclusion that I didn't need RDMA or DCB or some of the new cutting edge things in more expensive cards. Mainly I just needed 10GB wire speed instead of 1GB wire speed. The cards dropped into my existing VMWare environment without issue, and moving the Port Groups over was super easy. Would recommend it to anyone looking for a value option with solid performance for 10GB ethernet.

It has exceeded my expectations. I tried to find an external ethernet adapter online, but there were too many choices. The FS chat was a simple and easy process that made some sense of my online searching results and I felt comfortable with their suggestion for the JL82599ES-F2 Ethernet Network Adapter. It works great with Linux server and looks nice too!

Perfect fit to my Dell Server. My company send me generic NIC's, but they were both electrically and physically incompatible with my Dell Servers. Went on FS website and entered my service tag and got exactly what I needed. Super easy.

We started working with FS this year, and it has been great! Fast shipping, items are in stock, helpful and kind customer service associates.
Thank you to you and your team!

Windows 10 Pro, 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, or I would definitely consider re-ordering these.
