NVIDIA ConnectX-5 Ex EN 40GbE 2-Port QSFP28 PCIe 4.0 x16 Adapter

Overview
Many installed networks still run at 40GbE, and the NVIDIA MCX516A-BDAT is built for them. It is a ConnectX-5 Ex adapter with two QSFP28 ports rated at 40GbE and a PCIe Gen4 x16 host interface.
The QSFP28 cage is listed here while the speed is 40GbE, so confirm what your optics or cables are rated for before you order. Modules must match both the cage and the link speed of your switch. This is a typical detail to settle when upgrading hosts into a 40GbE switch fabric.
Two ports let you build redundant uplinks or connect a host to two different segments. Gen4 x16 gives the pair far more host bandwidth than they can use at this rate, so the card is a good fit in servers where the only free slots are wide ones.
The alternative number 900-9X5AD-0054-ST0 is recorded. New, refurbished and used offers are available. New and refurbished units have 1 year or 3 years of warranty, and used units have 90 days. Send the quantity and server model to begin a request.
