I have a specific question about using a this 2m passive SFP+ cable to connect the 10Gb uplink port on a switch to a NIC in a server.

Switch: Netgear GS752TXS

Server NIC: HP NC522SFP

I'm fairly confident that the switch and server NIC are fine, but can I use that cable to connect a 10Gb uplink port to an SFP+ NIC and achieve 10Gbps results? I've read this question and this question, but my $5000 project depends on this working and I would like an expert's advice before I spend the $$.Those three things are all I need, correct? No transcievers, since I am straight sfp to sfp?

Thanks in advance!

  • indeed, that's the purpose of direct attach cables.

Yes, you can do this in theory.

Keep your receipts because not all DAC cables work with every NIC/switch combination. It's best to use the cables that are known-good according to the switch manufacturer, though.

  • Thank you for your help - I made the purchase and now am waiting for everything to get here.
