NIC Selection

Didn't know it was against the rules to talk about the client side.

You're in a subforum for TrueNAS CORE hardware. Questions about which NIC to put in your Mac are as irrelevant here as questions about which motherboard to use for your next Windows build. There is an off-topic forum here, where such questions would be more appropriate.

What if someone uses as direct connection without involving a switch? Does it still apply the same?

Of course it does, because it's the same scenario. There's absolutely no reason you should concern yourself about having the same model of NIC at each end of a connection. It's obviously important that they both speak the same protocol.

Is that not allowed to do so? I mean my Mac has PCIe slots and I'm upgrading to my entire network to SFP+ this year. Didn't know it was against the rules to talk about the client side.

It's not so much against the rules than against logic. Expertise here is not necessarily about the client side—and then, not without you indicating what the client is.

The very same. Chelsio/Intel with matching Chelsio-coded/Intel-coded optics in the NAS; whaterver goes in your MacPro with its own matching optics.
But for the sake of serving your whole network and easier expansion it would be better to put a switch in there.

So, it means no one can ask what they should be putting in client side computer in the main TRUENAS Core/SCALE forum and can only discuss in off-topic forum? I mean is that you're trying to say for real?

Okay cool. Got it. Yes, i do have a Mikrotik CRS312-4C+8XG-RM switch and was using Base-T till now. So planning to upgrade it to SFP+ this year.

Hello,

I'm deciding between T580-CR or T50-CR. In a while, i plan to move to 40GbE so i think T580 would be the one. I've a couple of questions.

- Is there any newer T6 Card for 40GbE?
- Would it be really safe/fine to use a used NIC?
- Is there a major specs/performance difference between T580-CR or T580-LP-CR or is it just the form factor? The product brief itself says that T580-CR is Ultra High Performance Dual Port4 0GbE Unified Wire Adapter whereas, for T580-LP-CR, it says High Performance, Dual Port 40 GbE Unified Wire Adapter

This is your first post. It is in a "TrueNAS CORE" subforum and makes no mention of a MacPro. So the logical assumption is that you're seeking advice for a NIC in your TrueNAS CORE system. (We are geeks, not telepaths.)
The question for your MacPro would have fit in the "Off-topic" section of this forum, with an explicit mention of the MacPro/macOS. Or on MacRumors.

If you do want the same NIC on both ends, which is NOT necessary, the list boils down to Intel X520/X540/X710 cards for SFP+ and Intel XXV710 for SFP28.
On the Mac side, note that the mlx5 driver actually supports ConnectX-4 and later.

That's how I'd understand it, yes.

I mean is that you're trying to say for real?

Yes, it is. Why are you so incredulous at this thought? How is it that you understand "TrueNAS CORE Hardware" to mean "hardware for any device that might connect to TrueNAS CORE over the network"?
