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.

I think we have the same desk.

tofu@lemmy.nocturnal.garden on 17 May 23:27 collapse

It’s in a small cabinet, there’s no desk in the picture

whostosay@lemmy.world on 18 May 00:38 collapse

No shit, the bottom right of my desk has that same outer layer, and placement of hinges as holes for shelves, but I took the door off for ventilation for my PC.

joeldebruijn@lemmy.ml on 18 May 03:14 next collapse

Its not like Ikea standardised that for use in dozens of cabinets …

tofu@lemmy.nocturnal.garden on 18 May 08:12 collapse

Oh, is it the Ikea one? My wife has that one and it looks very similar indeed! The cabinet is Ikea as well admittedly.

Nice rack! I really like these small form racks.

Nice rack!

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

I’m most impressed by the printed rackmount SFF mounts. Great idea.

Lookin pretty slick, I dig it.

Did you 3D print the rackmounts or is there a place to get smallish ones like this?

tofu@lemmy.nocturnal.garden on 17 May 23:44 collapse

Thanks! Got it all printed from a friend, fortunately there’s plenty STLs out there.

Some people are selling printed mounts for common devices on Etsy but the ones I found were horrendously expensive.

MoogleMaestro@lemmy.zip on 18 May 00:32 next collapse

The mini rack is pretty decent, but I wish that the size decided was a 12" or so rack, so that more computer hardware could fit without the struggle.

I’m sure more stuff will be made the accommodate this scene though.

tofu@lemmy.nocturnal.garden on 18 May 08:13 collapse

Since most rackmounts are 3d printed, everyone with a little knowledge could just add 2" to the files. The rails are width-agnostic. The power strips could be hard to find in 12", but I’m sure printing 2" extenders is possible as well!

DannyBoy@sh.itjust.works on 18 May 01:32 next collapse

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

tofu@lemmy.nocturnal.garden on 18 May 08:10 collapse

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

tehBishop@sh.itjust.works on 18 May 17:57 collapse

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

tofu@lemmy.nocturnal.garden on 19 May 19:52 collapse

The latter, it’s all 3D printed rackmounts

B0rax@feddit.org on 18 May 05:29 next collapse

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 on 18 May 08:07 next collapse

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.

B0rax@feddit.org on 18 May 10:40 collapse

Thanks!!

thermal_shock@lemmy.world on 18 May 08:09 collapse

You can buy the rails by themselves if you wanted to make your own. Using finished lumber works very well if you’re handy with tools.

I made my own, but normal size to fit a specific space in my closet.

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

tofu@lemmy.nocturnal.garden on 18 May 09:14 collapse

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

I didn’t know there was more than one rack width. How many standard rack widths are there?

tofu@lemmy.nocturnal.garden on 18 May 15:31 collapse

I think 19" is still the standard one, 10" is getting more and more popular and there’s some fringe other widths mostly for niche use based on 3D printed parts.

Computer stuff

sugar_in_your_tea@sh.itjust.works on 18 May 15:23 collapse

My guess, from top to bottom:

  1. Router
  2. Server
  3. Server
  4. Switch (apparently 10.0.0 subnet)
  5. rack mounted drives (JBOD?), probably connected to one of the servers
  6. UPS? Battery backup for something on the rack
  7. Extra cable storage
tofu@lemmy.nocturnal.garden on 18 May 16:05 collapse

Almost correct! 1. is just a firewall, the router is not in the rack. I wanted to have this separate from the “family lan”. 6. is a mini PC to which the drives are connected, acting as a NAS.

sugar_in_your_tea@sh.itjust.works on 18 May 17:34 collapse

I take it the 192.168.1 subnet is the family lan?

tofu@lemmy.nocturnal.garden on 18 May 17:44 collapse

No, WAN is the family lan. It’s connected to one of the actual router’s ports (some Fritzbox connected to the ISP). 192.168.1 is inactive, I was just messing around with it when I got the unit.

iempqob4@lemmy.world on 18 May 15:07 next collapse

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 on 18 May 15:25 collapse

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: de.aliexpress.com/i/4001152236337.html?gatewayAda…

Landless2029@lemmy.world on 18 May 17:03 next collapse

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 on 18 May 17:31 collapse

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 on 18 May 17:43 collapse

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.

tofu@lemmy.nocturnal.garden on 18 May 17:54 collapse

Yeah maybe I’ll try to fit in some faster Ethernet adapters at some point, but currently it’s mostly just the daily VM snapshots and since those are automated, the speed isn’t that important anyways. Just in case of a potential recovery.

Offsite backup at some family member’s place is planned at some point as well, but not fully thought through yet.

Landless2029@lemmy.world on 18 May 18:56 collapse

I have a peer that manages his father’s IT needs.

He setup loads of server stuff there with an IPSEC tunnel to home so he does cross backup back between the sites. He’ll setup something like a game server at the office on a VM mapped to an obscure port then a registered domain so the family can game together. Fun stuff.

He doesn’t charge his dad for IT needs. They just expense all the server stuff to the business along with a secure location (building has proper physical security) with managed AC for his heavier 24/7 server needs. He can also order decent gear for the rack.

tofu@lemmy.nocturnal.garden on 18 May 19:19 collapse

That sounds like a good opportunity for offsite backup!

What are the SATA cables connected to? Does one of the lenovo tiny PCs have an interface for four SATA connectors?

tofu@lemmy.nocturnal.garden on 18 May 17:59 collapse

They are connected to the mini PC below. This mainboard has 4 connectors.

@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 on 18 May 19:17 collapse

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 on 18 May 21:09 collapse

@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 on 19 May 11:22 collapse

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.
