matthewcroughan @fosdem | Oh, trying to avoid that because hot | 12:10:34 |
emily | the Broadcom chip that powers the 80–100 m 10GBASE-T SFP+s runs much cooler | 12:10:42 |
magic_rb | You think that native 10gb will be less hot? | 12:10:48 |
emily | just make sure you get ones with that | 12:10:48 |
emily | there are cheap ones on AliExpress | 12:10:52 |
emily | but also ^ | 12:11:01 |
emily | it's still cramming the same stuff into the same ports | 12:11:07 |
matthewcroughan @fosdem | I don't mind the switch getting hot compared to the bpi-r4 | 12:11:18 |
emily | admittedly probably more surface area | 12:11:18 |
magic_rb | In reply to @matthewcroughan:defenestrate.it I don't mind the switch getting hot compared to the bpi-r4 Yes, so why not copper? What | 12:11:31 |
emily | uhh | 12:11:27 |
matthewcroughan @fosdem | I want the bpi-r4 to remain cool because I don't trust it to run at those temps stable | 12:11:32 |
magic_rb | I dont get it | 12:11:33 |
emily | can you make up your mind? | 12:11:36 |
magic_rb | Yes | 12:11:36 |
magic_rb | You run fiber between the bpi and the switch | 12:11:46 |
magic_rb | And 10gig copper sfp between switch and computer | 12:11:54 |
magic_rb | Which part of this is not making sense | 12:12:00 |
emily | ^ | 12:12:03 |
matthewcroughan @fosdem | Why involve the SFPs later, when I could just have regular copper cat6a | 12:12:25 |
matthewcroughan @fosdem | and tell people to get a cheapo 32 quid sabrent 5gbps dongle later | 12:12:51 |
emily | because you can get a more flexible switch that also works with non-10GBASET | 12:12:52 |
emily | like does that thing you want even support negotiating lower data rates? | 12:13:02 |
emily | ok it does | 12:13:11 |
matthewcroughan @fosdem | now that could be the thing that kills it | 12:13:12 |
emily | so there's that at least | 12:13:13 |
emily | but like you can get something cheaper off AliExpress and a multi-pack of good Broadcom chip 10GBASE-T SFP+s | 12:13:38 |
emily | and have more flexibility for later | 12:13:43 |
matthewcroughan @fosdem | Yeah so I could get this 100 quid switch that pumps out 10GbE, and then people can grab a cheapo sabrent usb c dongle, and they'll be able to get 5gpbs on the LAN | 12:13:45 |
matthewcroughan @fosdem | total cost is less than 200GBP | 12:13:54 |
