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.
