 magic_rb | And our "but can it run nixos" attitude :) | 13:10:37 |
 Emantor | In reply to @emantor:stratum0.org
I tried to find some references, mostly remembered it from the OpenWRT GPN session, let me check… These look to be the rtl930x/rtl931x devices, but they are MIPS devices… | 13:12:57 |
| 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 (clat on linux when) | 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 (clat on linux when) | 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 (clat on linux when) | Redacted or Malformed Event | 13:15:13 |
| hexa (clat on linux when) | ah, lol | 13:15:18 |
| hexa (clat on linux when) | 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 (clat on linux when) | yeah, same | 13:20:54 |
| hexa (clat on linux when) | but otoh I don't want a full sfp+ switch either for home usage | 13:21:22 |
| hexa (clat on linux when) | copper sfps are too expensive for that 😄 | 13:21:30 |
 adamcstephens | In my understanding they also draw significantly more power | 13:22:11 |
| hexa (clat on linux when) | more than specced for the port, yeah | 13:22:30 |
| hexa (clat on linux when) | otoh dacs tend to use less power than a copper link for some reason I don't grok | 13:22:54 |
| hexa (clat on linux when) | the new double port 10Gbase-T card from intel still uses 5.7W with both ports up | 13:24:29 |
| hexa (clat on linux when) | and an SFP+ module usually eats less than a Watt | 13:24:41 |
| hexa (clat on linux when) | at least up to and including LR optics | 13:25:16 |
| hexa (clat on linux when) | 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 |
