A lot of those modules would work fine if the companies didn’t fuck with their drivers.
The Linux ixgbe driver (for Intel 82598 and 82599 chipsets) was submitted with a whitelist for Intel SFP+ adapters. Linux devs added a module option to shut off the whitelist, and tons of stuff is perfectly compatible.
DACs are great, agreed. However try telling that to the guy next door. The reason ethernet got to be so popular was because of how familiar it was and similar it us to telephone wire. There were several other competing standards befofe ethernet won.
10GbE cards and switches help regular folk upgrade without needing to learn about DACs.
Yeah, that power consumption is a non-starter. Even assuming a relatively modest $0.15/kWh, that’s ~$200/year, and just for a switch. 10GbE is nice, but I’m not convinced it’s worth that much. 2.5G is plenty for a fraction of the power draw.
I’d like something that can replace my dinky little unmanaged 16-port gigabit switch for less than $300. Right now The only things I can find in that price bracket have maybe 5 ports. I’d settle for something that can just do 2.5/5Gb on all ports.
That’ll be a while, there isn’t much push yet (1gbe is still pretty fast) and you can do 2.5 if you want to push, they’re basically starting to replace 1gbe with 2.5gbe as a drop in.
WiFi kind of screwed everything because it’s 90-95% of all user clients, so if wifi can’t handle the bandwidth, the bandwidth is considered ‘commercial’ and they charge you through the nose.
16x2.5gbe with a couple of 10gbe uplinks (a couple so you can either daisy chain, or connect 1 to another switch and another to a sever with 10gbe) would be amazing - that’d handle wifi on a single port and allow multiple devices to all use their full 2.5gbe
i’ve seen a couple with 5x2.5gbe and 2xSFP+, which i guesssssss is okay
Can we finally get some affordable 10GbE switches too?
What about a cheap low power PC, like a thinkcentre, with a couple of these cards? Could double as a NAS, or is security barring that?
I’m not sure where security comes in for this, but that sounds like a reasonable build to me.
I was thinking about the switch most people have I guess, the xDSL “box” who doubles up as a gateway and protects from intrusion and so.
Right?! Most affordable 10G switches are SFP+ which requires a lot more research to make sure you get the right modules and cabling.

Just use DACs within the rack. Single mode fiber patches and SFP+ optics are also cheap and easy to find.

Always amazes me how few people seem to know about DACs. I use them extensively in racks. They’re inexpensive and easy to use.
Cisco c3850-12x48u is about $150 on eBay.
The main problem is the idle power consumption. About 150w with nothing plugged in.

Not to mention the fans volume.
what is “affordable” to you? there are $100-$300 10GbE switches out there.

Best I can do is 8x2,5 +2SFP+
The CRS310-8G+2S+IN at 250€. Good luck with configuration though

I have a few 4x2.5gbe and 2x10gbe, and I think one is 8x2.5 + 1x10gbe.
Theyll get better, networking is actually easy to sku once you get going, they’ve just enjoyed the premiums till now.
And again, wifi was considered the main connector, which is why we got 2.5gbe in the first place, it fit 802.11ac and most of ax.
