About this item
For homelab builders and data center techs, the Mellanox ConnectX-5 MCX516A-CDAT is a dual-port 100GbE network card with QSFP28 ports. An independent eBay seller lists this one as open box at $399.99, so read the condition notes closely.
What do I need to run a 100GbE QSFP28 network card?
You'll need a server or workstation with a suitable PCIe slot, compatible QSFP28 transceivers or DAC cables, and a switch or a second card on the other end.
- Open box condition: read the seller notes and photos for the bracket type and any wear.
- Firmware: ask whether the card has standard Mellanox firmware or a server maker's version.
- Cables: the title doesn't mention optics or cables, so budget for them.
- Cooling: 100GbE cards run warm, so plan for airflow over the card.
