NVIDIA ConnectX-5 EN 50GbE 2-Port QSFP28 PCIe 3.0 x16 Adapter

Quantity (units)
Overview
Two QSFP28 ports, each at 50GbE, sit on the NVIDIA MCX516A-GCAT. It is a ConnectX-5 EN adapter with a PCIe Gen3 x16 host interface, and it is the dual-port option for servers that want two fast links rather than one.
A pair of ports gives you a choice of designs. You can cable each port to a different switch for resilience, or connect both to the same switch where the host needs more aggregate throughput. Either way, the cages are QSFP28, so the modules or cables must be rated for that form factor and the switch ports must support 50GbE.
The x16 connector uses the full width of a Gen3 slot, and mechanical fit is worth confirming in compact chassis. NVIDIA's code 900-9X5AD-0055-ST0 is recorded as an alternative part number for this card, which helps when a supplier lists it that way.
This part is available in all three conditions. New and refurbished cards carry a choice of 1 year or 3 years of warranty, and used cards carry 90 days. Send the quantity you need and the server model, and we will reply with pricing.
