NVIDIA ConnectX-5 Ex EN 100GbE 2-Port QSFP28 PCIe 4.0 x16 Adapter
MCX516A-CDAT · Refurbished · 1 year warranty
The Ex in ConnectX-5 Ex marks the PCIe Gen4 generation of ConnectX-5, and the NVIDIA MCX516A-CDAT uses it: two QSFP28 ports at 100GbE connected through PCIe 4.0 x16. A Gen4 slot gives the two ports more host bandwidth than a Gen3 slot of the same width.
That is the practical reason to choose this card over a Gen3 ConnectX-5 EN when your server has Gen4 slots and the workload keeps both ports busy. For hosts that only offer Gen3, the title shows other cards in the family built for that bus.
You will need QSFP28 modules or cables for both cages, and a switch that supports 100GbE on those ports. Check the mechanical fit of an x16 card in your chassis before ordering.
NVIDIA's alternative code 900-9X5AD-0056-ST7 is on file for this part. It is offered refurbished and used. Refurbished cards have 1 year or 3 years of warranty, and used cards have 90 days. Tell us the quantity and platform with your request, and we will reply with availability.
