What do you run on your cluster? CAD compute?

No, but that'd be neat! I don't have GPUs in my cluster though. My big services are a Ceph cluster, a VPN, Borg (backups) and a K8s cluster (using kubespray). In K8s I have the main stuff: Plex, Gitlab, Gitlab runner (for CI), vaultwarden (passwords), miniflux (RSS, might be moving to freshrss though), rust desk (remote-desktop), home assistant (smarthome). My next project is to stream metrics into grafana. I have so…

> I have soil moisture sensors in my garden connected to stm32 boards, I just need to setup the receiving side and I can control my drip lines (they're using opensprinkler) with soil moisture information along with weather info.

This is a use case close to my interests. I want a network of environmental things monitoring and doing some detection stuff.

I do use Rclone as well, but Cryptomator has one feature that rclone does not, it allows me to access my data "on the go" from my phone. Personally i have never experienced any of the issues you mention, but my Cryptomator vaults are also mostly below 1TB in size.

If you are using android there is RCX ( https://github.com/x0b/rcx ) as a frontend to rclone. Rclone can also be used in termux. Not sure about apple.

Looks good but the last update was in 2021. Is this still being worked on?

I used to have a home network, until lightning hit nearby. It came up the power connection and the copper phone connection. The modem/router/switch fried, then it spread out though the twisted pair Ethernet and fried every interface connected to the network. These days I use WiFi unless I really need low latency / high reliability in a particular location. Optical would be nice, but WiFi is the poor man's lightning s…

When I was younger lightning struck our apartment building and it killed my consumer router. I replaced it and put it on the surge protector.

A few months later we got struck again. The router survived but the building caught fire.

Now that I'm older I just accept the risk that "sometimes nature hates you". Instead of jumping through hoops to protect my gear from nature I just set aside money to replace anything I can't afford to lose.

Life's too short to play tug of war with the planet and I'd rather set aside $50/month to pay for replacements when I need them.

I've also been curious about this in the context of making a dumbwaiter, but not enough to do the research. I would think having passive automatically closing fire rated doors would take care of it, but I don't know.

You could look into it but I think the reason laundry chutes aren't made anymore has more to do with kids getting stuck in them and less to do with fire code (after all, stairways are chutes connecting floors).

Got stuck in a clothes a chute growing up, can confirm that those things are evil.

And not a single mention of the noise level in this room. Those rack servers get insanely loud. I had a single SuperMicro in the basement one summer and it had to go after a month or so. You could hear it everywhere.

Was it a 1U server? 2U and 4U servers can be typically be configured or modified to run at a noise level comparable to a gaming desktop. Performance 1U servers you'll hear through the floor though for sure. I can tell you my 1U R620 servers lasted less than 6 months before I sold them for 2U R720s. I still wouldn't want to sit in a room with the R720s but you couldn't hear them through a door. Sold those when I moved…

Definitely a performance server. Multiple high-pitched fans running nonstop.

Curious why you didn't stack them like... 1. 24p Patch Panel (Odd ports of switch) 2. 48p Switch 3. 24p Patch Panel (Even ports of switch) 4. 1u Cable Mgmt Then you could have bought 4-6" Cat 5e/6a pre-made patch cables to connect in the majority of your patch panel ports. The only cables that would traverse through the cable mgmt panel would be longer cables to the servers in your rack. I have a similar Cisco switch…

The reason its arranged like that is because it started as 1 switch and 1 patch panel, and slowly evolved, so its not ideal, but I am fairly happy with the outcome If I could re-rack it all, I might make some changes. But that means turning everything off, and I'm not sure when, if ever, I want to do that

Great setup!

When I put together my own home setup (see https://www.reddit.com/r/HomeDataCenter/comments/ktz6yo/my_s... )

I had the patch panels above a collection of switches in both the MDF and IDF closet. About a year in I rearranged it to the more common interleaved switches and panels, mostly just to make it look a bit cleaner.

I moved from 10g to 40g for switch interconnects in a few places, as well as used the fiber I installed to do 10g to most of the desktops, etc. Fun stuff for sure!

To all the comments on energy usage, check this out! this person is using solar power, https://blog.networkprofile.org/17kw-enphase-solar-install/

I have a similar network setup (actually a bit bigger) and a much larger computation setup. I also have a 20kw 53 panel solar setup, and a complete 42kwh battery setup.

Overall power usage throughout the year for me is pretty high, on the order of 8MWh/month, and I get about 25 MWhs of total solar production. My servers and network gear take about 4kw sustained, which is 35MHws, so my solar covers about 70% of my computation and network power usage. I live the NW, so I produce most of that power in the central 5 months of the year.

I find this really disturbing. On the one hand this looks really nerdy and cool but then I see the immense amount of hardware that also relies on power... so much power. This is completely unnecessary but then I also see the pictures of an F150.. so yeah it makes sense. I have to categorize this as a (un)typical American person that does not care about the environment. Do like the fact that he runs a RIPE probe thoug…

Yes, we should care about the environment. No, we should not be using less energy, but more. The way we use energy is the reason why it hurts the environment, not the amount of energy. I think this mindset is hurting our ability to innovate.

Cool setup. I have worked in Telecom industry before and going to build something similar from second hand devices, but then switched to dev and now mostly wires left (sold all this telecom stuff to pay expences) :)
