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.
Damn bro... Nice rack. ππ
KEIN GOTT, KEIN STAAT, KEIN KABELSALAT!
love it :D
Yeah, couldn't resist the sticker :D
Ah, it looked like the work of a lasercutter.... Guess I'm stealing the design :D
can i order the svg?
Idk, you can probably ask the owner via the shop
heh, rack
that is hot
π₯π₯
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.
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
What are the SATA cables connected to? Does one of the lenovo tiny PCs have an interface for four SATA connectors?
They are connected to the mini PC below. This mainboard has 4 connectors.
oh yeah shoot, sorry, I skipped past that comment. Thanks for clarifying, you've got a super neat setup!
Thanks!
Shopping aliexpress most are 2.5 drives. I get that they're lower power but 3.5 drives offer much more storage...
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.
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.
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.
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.
That sounds like a good opportunity for offsite backup!
Someone tell me what everything does here pls
Computer stuff
My guess, from top to bottom:
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.
I take it the 192.168.1 subnet is the family lan?
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.
I didn't know there was more than one rack width. How many standard rack widths are there?
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.
@tofu I like it. Your βfor nowβ comment is on point; there is always more to do!
For comparison, here is my 19β 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.
#HomeAutomation.
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.
@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 donβt rely on the UPS for surge protection. For that, I use upstream Tripp-Lite outlets.
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.
@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. Youβll find power conditioning in pretty much all data centers.
Does that sticker say "no God, no State, no cable salad" in German ? Because that is peak Lemmy.
Yes, "Kein Gott, kein Staat, kein Patriarchat" and similar ones are the German versions of "No gods no masters". Got it from Kaoskvlt
Nice rack! I really like these small form racks.
I'm most impressed by the printed rackmount SFF mounts. Great idea.
Nice rack!
That exact same phrase is used in a very different context in other communities!
Like when you set up 10 pins for someone else to knock down with a ball and it's pretty symmetric?
Or when youβve smoked the most amazing ribs
Das da unten sieht mir aber nicht nach "kein Kabelsalat" aus
Die sind nicht angeschlossen, die zΓ€hlen nicht!
Nur weil Kabel den Anschluss verlieren, darf man sie nicht direkt ausschlieΓen!
Lookin pretty slick, I dig it.
Did you 3D print the rackmounts or is there a place to get smallish ones like this?
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.
Very cool rack. Neat to see the M910Q rack mounted. Love those computers.
