Help with recommending a transceiver for Mellanox ConnectX-3 40GB QSFP Dual Port PCI-E Network Card - CX354A

Recommended Posts



I'm going 10Gb Ethernet (because already have cat6a all in place.

After getting half of my network done and working I came to unraid with my used card i ordered from ebay and realized it doesn't have SFP+ connector for my transceiver.


is it possible and can i even get one for QSFP > 10gb ethernet? If so can someone recommend one (cheap but reliable, used is fine).

Thanks in advance
