Been planning to migrate from my Supermicro monolith server for a while and finally finished the migration. Red thing is opnsense on an APU engine, Lenovos run a proxmox cluster, below is a mini PC with attached JBOD running TrueNAS.

Next step is to get another shelf for my Raspi and openDTU.

Does that sticker say "no God, no State, no cable salad" in German ? Because that is peak Lemmy.

[-] tofu@lemmy.nocturnal.garden 2 points 1 month ago

Yes, "Kein Gott, kein Staat, kein Patriarchat" and similar ones are the German versions of "No gods no masters". Got it from Kaoskvlt

KEIN GOTT, KEIN STAAT, KEIN KABELSALAT!

love it :D

[-] tofu@lemmy.nocturnal.garden 0 points 1 month ago

Yeah, couldn't resist the sticker :D

[-] nibbler@discuss.tchncs.de 0 points 1 month ago

Ah, it looked like the work of a lasercutter.... Guess I'm stealing the design :D

[-] 30p87@feddit.org 2 points 1 month ago

Das da unten sieht mir aber nicht nach "kein Kabelsalat" aus

[-] tofu@lemmy.nocturnal.garden 1 points 1 month ago

Die sind nicht angeschlossen, die zählen nicht!

[-] sntx@lemm.ee 1 points 1 month ago

Nur weil Kabel den Anschluss verlieren, darf man sie nicht direkt ausschließen!

[-] irmadlad@lemmy.world 2 points 1 month ago

Nice rack! I really like these small form racks.

[-] Tanoh@lemmy.world 1 points 1 month ago

Nice rack!

That exact same phrase is used in a very different context in other communities!

[-] dzsimbo@lemm.ee 1 points 1 month ago

Like when you set up 10 pins for someone else to knock down with a ball and it's pretty symmetric?

[-] microcapybara@sopuli.xyz 2 points 1 month ago

Or when you’ve smoked the most amazing ribs

[-] DannyBoy@sh.itjust.works 0 points 1 month ago

Very cool rack. Neat to see the M910Q rack mounted. Love those computers.

[-] tofu@lemmy.nocturnal.garden 0 points 1 month ago

They're great, super neat small computers and available used for little money.

[-] tehBishop@sh.itjust.works 1 points 1 month ago

Do they have rack mount option or are you using third party hardware for that?

[-] tofu@lemmy.nocturnal.garden 2 points 1 month ago

The latter, it's all 3D printed rackmounts

[-] B0rax@feddit.org 0 points 1 month ago

I am currently also looking for a 10“ rack. Where did you get this one? It sounds like you are from Germany (at least according to the sticker) and so am I.

[-] tofu@lemmy.nocturnal.garden 1 points 1 month ago

Got it in parts from different sources. I've generally been looking for used parts. The rails and screws are from Retourenking, the shelf and the blinds from Kleinanzeigen and the power strips from 25now.

If you're looking for a single source to buy new, check the Assmann Digitus stuff. I think they're available at Amazon.

[-] iempqob4@lemmy.world 0 points 1 month ago

Can you share any details on the JBOD? How are you connecting it to the PC? I'd love something similar for my miniPC server.

[-] tofu@lemmy.nocturnal.garden 0 points 1 month ago

It's an Olmaster one that fits a 5,25" bay. It has 4 SATA connectors in the back and a single Molex for power. The SSDs can easily be swapped in or out.

It's this or something very similar: https://de.aliexpress.com/i/4001152236337.html?gatewayAdapt=glo2deu

[-] Landless2029@lemmy.world 0 points 1 month ago

Shopping aliexpress most are 2.5 drives. I get that they're lower power but 3.5 drives offer much more storage...

[-] tofu@lemmy.nocturnal.garden 0 points 1 month ago

I'm all on SSDs since I don't need that much storage, so 2.5 is what I need anyways. There's a 3x ZFS mirror of 1.8TB SSDs in there, 4th bay is currently empty.

[-] Landless2029@lemmy.world 1 points 1 month ago* (last edited 1 month ago)

Damn. Ethernet is indeed your bottleneck there. I love your rack but I'd go more for a higher storage configuration.

With B2 offsite backup.

Someone tell me what everything does here pls

Computer stuff

[-] meltedcheese@c.im 0 points 1 month ago

@tofu I like it. Your “for now” comment is on point; there is always more to do!

For comparison, here is my 19” 15U rack , also a work in progress: PDU, ventilation, 16 port switch, 2U mount for up to 8 Raspberry PI s or NAS., and a 8x KVM HDMI/USB switch to connect the RPis to a small monitor, keyboard and mouse on top. I use one RPi for #HomeAssistant, another for home security cameras and other video, one for HomeBridge, one for Pi-Hole, and other for experimentation and testing. A UPS is in back. I Iove that the rack is on wheels because I frequently move it to get access to the back.

[-] tofu@lemmy.nocturnal.garden 0 points 1 month ago

Oh cool! Wheels are definitely a good idea. I thought about a UPS but our grid is super stable and apparently they cause their own problems now and then.

[-] meltedcheese@c.im 1 points 1 month ago

@tofu UPSs have some glitches, but the benefits of the power conditioning they do (the good ones) outweigh the trouble of the rare glitch. For example, reducing wear and tear on the electronics they power. Also, the performance of some electronics is highly sensitive to the quality of power provided (e.g., no under- or over-voltage conditions). I don’t rely on the UPS for surge protection. For that, I use upstream Tripp-Lite outlets.

[-] tofu@lemmy.nocturnal.garden 1 points 1 month ago

This is the first time I've heard about using UPS for something other than powering computers in case of a blackout. Shouldn't the power supplies take care of the rest? Never heard of reducing wear and tear by external components.

[-] meltedcheese@c.im 1 points 1 month ago

@tofu It depends on your local power system. At my house, I see frequent under voltage conditions. Also, some devices are more tolerant than others. You’ll find power conditioning in pretty much all data centers.
