Can we finally get some affordable 10GbE switches too?

[–] yaroto98@lemmy.org 33 points 5 days ago (3 children)

Right?! Most affordable 10G switches are SFP+ which requires a lot more research to make sure you get the right modules and cabling.

[–] eleitl@lemm.ee 20 points 5 days ago (2 children)

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

[–] yaroto98@lemmy.org 12 points 4 days ago

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.

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.

Cisco c3850-12x48u is about $150 on eBay.

  • 802.3bt (60watt) PoE on all ports
  • 36x 1gig rj45 ports
  • 12x 1/2.5/5/10gig rj45 ports
  • Has a module slot that you can add 4x or 8x (8x is rare so expensive) 10gig sfp+

The main problem is the idle power consumption. About 150w with nothing plugged in.

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.

This is going to be a huge help for home video editors.

[–] REDACTED@infosec.pub 2 points 3 days ago

I recently started using USB 3.2 2x2 (20Gbps) and it's orgasmic experience to what I had before

[–] SirEDCaLot@lemmy.today 37 points 4 days ago (9 children)

About damn time. We got a boost every few years from 10 to 100 to 1000. Then we just... Stopped. Stagnated. It's understandable why, for a good long time one gigabit was all anybody needed, 100 MByte/sec is pretty good even for a NAS.

Of course then fiber ISPs got in the game, now in a lot of places you can buy 7-8gbps as a consumer product. And even multi-gig, which was supposed to 'fix' this, really ended up being insufficient. You could make a salad argument that multi gig was a waste of time and we should have just started moving to 10 gig.

Unfortunately, 10 gig switches still carry a significant premium. But this will start to shake that up. Sooner the better.

[–] ftbd@feddit.org 13 points 4 days ago (3 children)

100MB/s are frustrating for a NAS. SSDs have been common for a decade, and the old spinning rust storage in my NAS is still faster than the network can handle?

but home Internet is still stuck at Gigabit speeds.... and only in some cases are they maybe letting you go to 2 Gb. Wasn't there that post floating around lemmy a while ago about how China can potentially give everyone like 5Gb for home or something? Can't find it now but swore it was here....

[–] lud@lemm.ee 23 points 4 days ago (7 children)

That depends on where you live. I could get 10 Gbit/s WAN if I wanted to pay the subscription for that but 500 Mbit/s is enough.

Also 10 Gbit/s is mainly useful for LAN. Like connecting to a NAS.

I think 10GbE is more intended for local applications than for internet. Say, you have a NAS with a RAID array of nvme drives for video editing purposes that you want to access from a few workstations.

Even the other day I was quite happy to have 2.5GbE when I installed my new gaming PC, and steam was able to pull all my games directly from my old computer rather than downloading them over the internet again.

Anyway, LAN speeds have always been an order of magnitude higher than common internet speeds, so I don't see the issue.

[–] interdimensionalmeme@lemmy.ml 5 points 3 days ago

Yes, this is the chicken and egg logic we have been served for the last 25 years that we have spent locked at 1 gigabit. This is because commercial players still had money left to milk to 10GBe deployments and 25 years later it it becoming obsolete in these environment. So we can have the free upgrade to 10GBe as the commercial deployments switch to 25, 40 and 100 GBe.

The thing manufacturer want to avoid collectively is product line cannibalization. And that means making sure that 10GBe was not the port you find on every random computer.

Of course, with the cloudification of general purpose computing. Most people in their homes just need a browser and streaming desktop client. So there could be other forces at play at preventing high speed LAN proliferation.

Imagine if a company could just make a 100$ nvme drive you can connect into your home router and it "just working". No cloud, no serves, no redirect. It opens the port, update IP dns client, update certificates, works everywhere.

[–] 50MYT@lemmy.world 4 points 3 days ago (1 children)

The China article was true that they launched the service, but bullshit they are the fastest.

Plenty of other countries are running 10GB and faster services you can get to your home.

Sweden for example

Realtek are monsters of semiconductor creation.

Destroyed

  • sound card industry
  • network card industry

What's next?

[–] muusemuuse@lemm.ee 18 points 4 days ago (1 children)

Literally anyone else could have done this. They all chose not to. So fuck them.

If only they were also monsters of incrementing the pcie device id when their chip revision breaks compatibility.

So you don't spend forever trying to Google on your phone or other laptop that you have to pull and rebuild the latest kernel, without an internet connection, because only that one knows that revision K needs power management set before the link will come up.

It's impressive that they got the power consumption down to less than 2 watts. I think this is the first 10GBASE-T NIC I've seen that doesn't have a heatsink on it.

[–] AA5B@lemmy.world 14 points 4 days ago (9 children)

And they did it on Cat5e! I have a Cat5e “trunk” that I really don’t want to try to restring, but it’s a choke point that I’d like to upgrade from 1Ge. If only someone will build SOHO switches with it

Excellent!

Now if we can only teach realtek how pci device id's work, so they don't use revision id's to control power management, and links silently don't come up if your kernel driver doesn't support it properly.

I know this was a decade ago, but yeah, I'm still pretty damn pissed.

[–] exu@feditown.com 34 points 5 days ago

Great to (maybe) see 10GbE coming and the initial price sounds reasonable compared to currently avaipable 2.5G and 5G Realtek adapters.

Apparently Linux 6.16 will have the driver included.
https://www.phoronix.com/news/Linux-6.16-Realtek-RTL8127A

Realtek itself has demonstrated its RTL8127 NIC working with an unknown switch using cheap CAT5E cables, and the company’s representatives at the booth emphasised this fact. However, we do not know which switch or router the company used. Yet, most 10GbE routers and switches are designed for CAT6 cabling.

Funny update about the cabling they used during the demo. There's really no reason Cat 5e couldn't work for short enough distances with little interference. It's more about the guaranteed minimum distance you can get, 55m with Cat 6 and the full 100m for any rating beyond that.

[–] avidamoeba@lemmy.ca 31 points 5 days ago (1 children)

Wasn't it Realtek who made 1GbE popular as well by making the cheap 8111 IC over two decades ago?

[–] InverseParallax@lemmy.world 15 points 4 days ago

And fucked it up by releasing the 8169 with a stepping change that added power management.

The kernel driver didn't know this, so links would silently not come up, and you wouldn't know why till you googled and learned you had to rebuild your kernel for your new motherboard.

[–] corsicanguppy@lemmy.ca 19 points 5 days ago (1 children)

At least it's not Marvell. But, man, can we pay another 17c and get .... I guess not Broadcom as they're waxing seriously dinkish, but who else?

[–] sugar_in_your_tea@sh.itjust.works 22 points 5 days ago (6 children)

Intel is probably still the gold standard. I'd pay a few bucks more to have something much more reliable.

Serious question: What do you use a 10GbE adapter for? Are there ISPs which offer 10gigabit bandwidth? I suppose it would be useful on a LAN

edit:

[–] mike_wooskey@lemmy.thewooskeys.com 28 points 5 days ago (6 children)

E.g., NAS on my LAN, especially for streaming high res video to devices in my house.
