Overview

Where the AN version drops security features, the NVIDIA MCX631105AC-GDAT keeps them: its title lists Crypto and Secure Boot. Everything else matches the one-port 50GbE ConnectX-6 Lx design, with a single QSFP28 cage and a PCIe Gen4 x8 connection.

Buyers usually reach for this card when a host has a free x8 slot and the switch side offers 50GbE on QSFP28. It suits hosts where one fast link is more useful than several slow ones. Make sure your cables or modules are QSFP28 rated, since the cage will not accept SFP28 modules.

Because a cousin card shares the speed and port, double-check the suffix when you order. The letters are the only difference between the Crypto and No Crypto versions on a quote.

The NVIDIA ordering code 900-9X601-0045-ST0 is an alternative part number. We offer refurbished and used units. Refurbished cards have 1 year or 3 years of warranty, and used cards have 90 days. Request pricing and include the server model.
