Emantor | See https://openwrt.org/docs/techref/targets/realtek and https://github.com/plappermaul/realtek-doc | 13:13:28 |
emily | right | 13:13:48 |
emily | yeah those are the ones I was looking at | 13:13:49 |
magic_rb | I have an idea, connect a orangepi zero to the management ethernet, put nixos on it, then flash openwrt on the switch and write a openwrt management nixos module :P | 13:13:54 |
emily | they should be able to run Liminix at least | 13:13:55 |
hexa | well I assume you get them used for cheap on ebay | 13:14:20 |
emily | cheap in relative terms yeah | 13:14:34 |
emily | but I haven't yet talked myself into spending ~$1k on a homelab switch | 13:14:55 |
magic_rb | https://www.ebay.com/sch/i.html?_nkw=mellanox+sn2010&_trksid=p4432023.m4084.l1311&_sacat=0 | 13:14:59 |
hexa | ohh, I linked the wrong one 😄 | 13:15:00 |
magic_rb | That is not cheap lol | 13:15:04 |
emily | oh, no you linked the right one | 13:15:11 |
emily | I just linked the other one | 13:15:12 |
hexa | Redacted or Malformed Event | 13:15:13 |
hexa | ah, lol | 13:15:18 |
hexa | I cannot brain right now, ok | 13:15:26 |
emily | the one from that post is not interesting to me, because it is gigabit copper | 13:19:06 |
hexa | yeah, same | 13:20:54 |
hexa | but otoh I don't want a full sfp+ switch either for home usage | 13:21:22 |
hexa | copper sfps are too expensive for that 😄 | 13:21:30 |
adamcstephens | In my understanding they also draw significantly more power | 13:22:11 |
hexa | more than specced for the port, yeah | 13:22:30 |
hexa | otoh dacs tend to use less power than a copper link for some reason I don't grok | 13:22:54 |
hexa | the new double port 10Gbase-T card from intel still uses 5.7W with both ports up | 13:24:29 |
hexa | and an SFP+ module usually eats less than a Watt | 13:24:41 |
hexa | at least up to and including LR optics | 13:25:16 |
hexa | so for anything >5Gbps just use SFP+/SFP28 if you can 🤷 | 13:25:51 |
magic_rb | A 1gig sfp+ module cant eat that much | 13:27:32 |
emily | AIUI it's because the range is much less | 13:28:18 |
emily | like 8P8C would be a lot simpler if it could only go up to 7 m | 13:29:00 |
