This was a swap out with another Intel nic in the same family running CentOS and nothing was necessary for the swithout.

Using HPE optics, I was able to connect this R640 server straight an QSPF+ expansion port on an Aruba 3810. Outstanding card and FS has been very helpful.

fast delivery and good pricing

Exactly what we needed! We regularly use these cards to link our Dell servers to Cisco switches. These network interface cards worked flawlessly on the servers and no compatibility issues so far. Would come again.

Talked with the AM online, I knew the dual port 40G QSFP+ network card supported 4069 rules in packet filtering based on VLAN, which could meet our network environment. The item was packaged well as the man guaranteed. Installed was easy, and I can use 40Gbps rate to deliver data now.

Professional advice from the FS team can be achieved via online talk. And they always reply promptly. Thanks for their recommendation #75604 40G network card for connecting our 40G Cisco switch, and the link is solid without any loss.

This network card was well packaged, I plugged it into my server motherboard, the CentOS system recognized the card, reconfigured my network and rebooted again and it was ready to use.

I wanted to buy a 40G adapter and modules to connect Cisco Nexus 3064 switch. Sent my requirements to FS AM, I quickly received a reply from the AM with the recommendation of #75604 adapter and #36157 module. For now, the transmission is stable.

Wanted to buy a new network card for our server, but we had installed one card in it, the server could only work with low-profile card. So we asked the sales the 40G cards supported low-profile or not. They gave us an affirmative answer, and explained that all their network cards were equipped with low-profile bracket as well as full-height bracket. We could install the new card on our server without any issue. Our linking distance was about 3m, so the sales suggested us use 40G DAC cable to connect the network card and the switch. We got the 40G network card and DAC cable on time. There was no damage to the protective box. Installed them on the server, no compatibility issues.

Bought four for our ASUS motherboard. We installed the cards and drivers immediately and did the test. They could be recognized by the server, and did the work that they supposed to do. A more cost-effective choice than using the Intel original products.

Perfect for our needs. We regularly use these cards to link 2 servers together for data migration, substantially reduces the transfer time. It is quite cost-saving and has worked flawlessly. I will definitely buy this again!
