So with Crypto mining being less profitable and miners selling their rigs for cheap I thought how can I get my self a cheap managed network switch. I saw mining motherboards with 12 PCIe 2.0 1x slots(4gbit bandwidth) and tought hey if I plug in some cheap 10g 2port network adapters I can make my own network switch with exactly...
Check out decommissioned Brocade or Ruckus switches on eBay if they’re available in your region. There’s a thread over on ServeTheHome with a licensed feature unlocking method that’ll get you fully enabled hardware for cheap cheap cheap prices.
On my ICX6450-24P I see like, <20W power use while shoveling packets through four 10G ports. PoE drives usage up, obviously, if I’m supplying power to things with it.
If you can find them the ICX7250 is a baller homelab switch, I paid <$250 for mine and I’m putting the 8x10Gb ports to good use. Low power draw here as well.
If you want bigger the ICX6610 is a power hog but offers a couple of 40Gb ports as well as 8x10Gb. These draw significantly more power, they’re powerpc rather than arm, and are loud compared to home gear but they’ll let you link a bunch of machines at 10Gb as well as two at 40Gb - which is awesome for a NAS and/or firewall. I want to say mine drew like 50W at idle so they’re not cheap to run over time.
I’ve also considered rolling my own whitebox router so I can connect 2.5 and 5Gb gear to the rest of my network but it’s not that much cheaper than just buying a cheap chinesium $200 dumb switch with 4-8x 2.5Gb ports and a couple of 10Gb uplinks.
Surprised I’ve never seen this DIY approach mentioned anywhere or thought of it before 🤔 - usually people end up going for those mini PCs that have multiple network cards soldered to the mobo itself
Rolling a whitebox router is so much :effort: when decommissioned enterprise gear is dumped on fleaBay so cheaply. Plus it’s almost impossible to rival the power efficiency of a commercial switch without blowing more money than you’d pay for one.
I’ve kicked the idea around as a way to hook up multigig devices to my network (managed 2.5Gb + 10Gb switches are still expensive) but by the time you’ve built the machine you’re looking at the same cost and you have to maintain it, plus your network is down for however long it takes to reboot the thing after kernel package updates.
Where I live 100W would cost me something like $25/mo to run, continuously, for the life of the device. I think my 8x10Gb + 24x1g switch draws around 15-20W if I’m not using PoE and I spent around $260 on it. Inside a year the commodity switch becomes cheaper to own even if I were given a whitebox equivalent for free.
If I lived somewhere with lower kWh costs I’d be happy to roll my own whitebox but it’s just not viable here.
I buy $2 sale priced ebooks from the play store occasionally and I’ve had a couple dozen hard right trash tracts from folks like Jordan Peterson dropped into my “Books for You” recommendations. The best part is that you can’t flag them as “not interested” from the play store, you have to open a separate app (Play Books), navigate to the same feed, find the book and then you can tell the algorithm to get that shit out of your face.
You can’t anymore. You used to be able to MitM traffic globally on Android by using something like Adguard as a local VPN but Google started verifying that the signing cert on traffic actually matches an expected sender like 2-3y ago.
