Overview
The X in this part number signals a 10GbE speed class on SFP28 hardware. The NVIDIA MCX4121A-XCAT is a ConnectX-4 Lx EN adapter with two SFP28 ports rated at 10GbE and a PCIe Gen3 x8 interface, which suits networks that are still built on 10GbE switching.
SFP28 cages accept the cabling you plan to use at this speed, so verify the optics or direct attach cables that your switch expects. The card's role is mostly as a like-for-like replacement or as a stepping stone: the connector style allows a later move to faster optics without changing hosts.
Because the rest of the family is named almost identically, match the full MPN to your system. Cards of different speeds can look alike, and only the letters in the number tell them apart.
NVIDIA's alternative code 900-9X4B0-0052-0T1 is on record. Refurbished and used offers are available, with 1 year or 3 years of warranty on refurbished and 90 days on used. Send your quantity and server platform to request pricing.
