Oracle / Mellanox ConnectX-3 QDR InfiniBand Network Card 40Gbps CX354A – Low Profile

Alright, so this is a used Mellanox ConnectX-3 card—specifically the CX354A model, sometimes branded as Oracle 7046442.

It's a QDR InfiniBand adapter pushing up to 40Gbps, which is still a beast for high-performance computing or building a super fast home lab network.

It's got a low profile bracket, so it should fit in just about any server chassis or desktop you throw it in.

The card has been used before, so there might be a little scuff or two cosmetically, but electrically it's fully operational and ready to rock.

No original box, just the card itself.

A solid pick if you need to connect to InfiniBand gear without dropping a ton of cash on new old stock.
