Good morning folks, question on what is the recommended go-to adapter for 2.5g Ethernet in FreeBSD 14.1? Before you respond, I've searched the forums and not found much. Most of the threads on 2.5gbe are folks talking about how pointless and stupid 2.5gbe is, it's just crippled 10gbe, it's pointless so don't bother. Well, hear me out, I have a specific use case.
I have an embedded system I'm building for a client that requires very low power passively cooled hardware. It also needs slightly more bandwidth than 1gbe can provide. 2.5 gbe is the next logical hop. I know adapters like the Mellanox and Chelsio 10gbe cards are well supported, however I read the spec sheets and these older server adapters all consume ~12 watts or so, which is too much. I've tested them, and they get scorching hot and are unsuitable for my use case. They all seem designed for a rack server with forced-air cooling in an air-conditioned data center.
Here's a Chelsio T520 with an 80mm fan blowing directly at it (on the test bench). The finished product can have no fans, and will be in a hot environment, so notgonnawork.
dev.t5nex.0.temperature: 62
The i225 adapter for 2.5gbe however consumes under 2 watts. Perfect. But the internet says the intel 225 is buggy and should be avoided.
Is there a "recommended" 2.5 gbe adapter here in 2024, for FreeBSD 14.1? (10gbe adapter is also acceptable, but it must only consume 4 watts or less).
Thank you in advance.
