R740 & Mellanox MCX416A-CCAT
Can anyone advise whether R740 will accept the above ConnectX-4 100G Mellanox card? My plan is to direct connect two R740 servers.

i can say that we successfully use the Dell version of Mellanox ConnectX-4 100 GbE QSFP Adapter in our R740xd servers. Our cards dont have the MCX416A-CCAT designation on them. I'm pretty sure the one you want to use will work, but we cannot guarantee it. Its also possible that the non-Dell version card may cause the fans to run higher than normal.

These cards work fine in my R740. I installed one each in two R740s, and could also team both ports on the card to get a 200 Gbps network connection. Sweet!

As I can see both server and the card are compatible with PCIe 3.0 x16 interface. But I can't search network cards " MCX416A-CCAT ConnectX-4 100G Mellanox". I can search part number in our tech spare part system. So without the Dell part number unfortunately we can't verify it. Might be sales team can help with it.
