Overview
Flexibility in slot generation is the point of the NVIDIA MCX512A-ADAT. The product name lists PCIe 3.0/4.0 x8, so this ConnectX-5 Ex card is described for both Gen3 and Gen4 hosts, which helps when a fleet contains servers of different ages.
The card offers two SFP28 ports at 25GbE. That is the standard speed for modern server access links, and the ports take SFP28 optics or direct attach cables. Only a x8 connector is needed, so it fits in slots that a wider adapter would not.
The suffix letters in the MPN separate it from other two-port 25GbE cards, so check them on your order. NVIDIA's alternative code 900-9X5AZ-0053-ST5 is listed for this card, which helps when matching against an older purchase record.
Refurbished and used offers are available. Refurbished cards come with a warranty choice of 1 year or 3 years, and used cards with 90 days. No new offer is listed. Include the quantity and the server platform when you send your request.
