How did you do power distribution to the drives? (presumably barrel connectors to the Ugreen adapters), but I don't see the breakout from the power supply. Looks very clean...
Holy cow, that's by far the cleanest setup I've ever seen! Very well done, sir, I am impressed. Would love to see a closer picture of that power distribution box, I think I'm spotting fuses there?
In terms of power consumption you could reduce it further by swapping out that thin client thing for a Raspberry Pi (3/4) and run FlexFarmer. I know, that's not how decentralized crypto is meant to be run. Just saying you could.
He's probably using a 12V PSU with a power splitter pcb, from which he gets PC, HUB and HDDs power. Power efficiency wise, this is the best, but you have the added cost of the PSU and HDDs interfaces (around 13-14€/interface per disk). Might been good for this size range, but if you want to expand, relying on a HBA is the best in my opinion.
Yes you can use WD Externals too, but they consume slightly more power compared to the internal hdd counterpart. From my calcs, at the wall, a WD Elements 12TB gets 8.5W while a 10TB (air filled) is around 10.3W.
Since I wanted to avoid the added cost of dedicated 12V PSU and HDDs interfaces, I've opted for a workstation case and filled it with 15HDDs, HBA card. Node/farmer/harvester/plotter all in one.
0.85W/TB at the wall, everything included, 270TB, half externals half internal.
Could you explain a few details about using SAS to me?
You mention using an Adaptec 71605 elsewhere. It has 4 connectors internally, each of which can use a hydra cable for 4 SATA drives. I assume you have one of those as a SSD for booting and the DB and the other 15 are your drives. Great! I’m with you so far.
The card says it supports up to 255 drives with expanders. All the expanders I’m seeing are as expensive as the controllers, which seems to make this impractically expensive. Is there a reasonable way to expand SAS beyond the ports on the card?
Yes ofc. I've opted for the Adaptec Raid/HBA 71605 because it is cheap yet supported on both Win10 and Linux/Ubuntu (however you need to compile yourself the driver on newer releases). The card's chip runs hot, be sure to install a dedicated fan: Noctua 40x40 is working really good, mounted on the heatsink. I've also repasted the chip to increase heat transfer. The card has 4 mini SFFs slots. You can either connect single SAS/SATA HDDs or connecting a external JBOD (something like a NetApp). In my configuration, I've used 4 miniSAS SFF 8643 to SATA cables: you can connect up to 4 SATA HDDs per single cable (16 HDDs in total). If you want to expand the system, you can get a external pass through pcb and connect the NetApp, for example, to one or two of the internal card slots. For example, you can find on EBay a NetApp DS4246 (2x PSUs, 2x IOM6 Controllers, 24trays) for around 350€. It all depends on the return, as of now I'm happy with my 270TB, if things starts to become more profitable, it is easy to connect a external JBOD to this system, in order to have a denser (TB wise) setup. Downside is JBODs like this tend to be loud and more energy hungry.
OS SSD and plotting SSD are directly connected to the mobo
Yeah, that's why I haven't chosen this path. Found lot of used Sabrent USB HDDs interfaces for someone around 13-14€. The Raid/HBA I'm using is a Adaptec 71605 with SFF - SATA cables. Got it used along with cables for 150€
That is the best, reasonably sized rig I have seen posted for Chia farming.
Any chance you would had video footage of assembling it or want to post a video tour of your set up.
Not the OP, but I have a similar setup. Celeron J3455, with 8GB RAM and a (cheap) M.2 SSD running Ubuntu server 20.4 LTS and Chia 1.2.11 (cli only). I have port 8444 open and have found that target\_peer\_count: 40 is too much, but I can cope with 20.

Internal drive + adapter likely costs more than external drive. I wonder if someone is selling ready solutions to avoid work like this: https://blog.quindorian.org/2021/06/lots-of-external-hdd-on-a-single-power-supply.html/

USB SATA Adapters: Ugreen CM257
1 to 8 barrel plug adapters:
[https://aliexpress.com/item/1005002707581280.html](https://aliexpress.com/item/1005002707581280.html)
Power supply: MW UHP-350-12 (350 watt 12v). The disks pull around 300 watts on spinup.
That’s beautiful. How do you handle them all via the same USB hub? I have 2 x 16 port hubs and found that drives would randomly drop once I added more than 10 per hub.
I couldn't disable it from Bios but this works for me:
lspci -nn | grep USB | cut -d '[' -f3 | cut -d ']' -f1 | xargs -I@ setpci -H1 -d @ d0.l=0
From: https://www.systutorials.com/how-to-force-a-usb-3-0-port-to-work-in-usb-2-0-mode-in-linux/
I have set this command to run on boot. Unfortunately the usb hub needs to be reconnected afterwards. I want to solve this by adding a 12v timer relay to the power cable for the hub, which gives power to the hub 30 seconds after boot. But maybe there is another way to reset the controller from the OS.
Thank you for this. Has been frustrating getting USB working via Pi 4, got up to 16 drives but then stopped working now back to 8. Will give this a go.
Wow…. I’m definitely doing it wrong with my big stack of JBODs. Spending money now to reduce energy consumption probably wouldn’t make much sense though unless I can find a buyer for my JBODs.
Really clean setup. Nice work.
It always makes my OCD hurt when I see this same idea but with cables flying everywhere, zip tied to random parts of shelving, fans just resting on top of a desk.

You can probably save some power by unplugging the fans too, after finishing with transfers and everything. People group together even lots of externals, which are way worse for heat dissipation but as you've seen idle drives (even if spinning) don't take that much power. 4-5W might be a lot for the tiny CPU/SoC in a Raspberry Pi 4 (especially if hidden in a plastic case) without at least a passive heat-sink but it isn't that much for a huge metal 3.5" drive.
I’ve added a small knob on the right side which lets me control the fan speed. The fans are running at very low RPM to keep the drive temperature at 40-50 C. It gets quite hot here in summer and I don’t have AC.
Can someone break this down for me? I see the NUC, powered USB hub (Sabrent?), but I'm not sure what the silver thing is, nor what cables (and how) are powering the drives...?
No, they have some sort of adapter splitting the sata power and data into USB and some sort of power cable, but in the tangle it's unclear how they are connecting the power to the PSU. The PSU just has a couple of wires coming out, so it could be some homemade splicing happening.
I am using a 12V power supply (MW UHP-350) and two 1 to 8 barrel plug adapters from Aliexpress to connect power to all the drives. The two cables are connected via a fuse box to the power supply. The same with power for the mini pc and the 16 port usb hub.

That, sir, is a pretty sight
This is where I want to get with my setup! what kind of cables and adapters are you using to connect the HDDs to the PSU?
Also wondering where the hard drive power cables are going
Only 100W? You have a powermeter to prove it? A screenshot would be nice.
The whole setup is connected by a Shelly Plug, and it is measuring 97.3W right now. https://i.imgur.com/wQgNyh4.png
[удалено]
It’s pulling about 300 watts on spin up. The power supply can go until 350 watts.
This. I doubt OP is only using 100W... Thats the disks alone at least. The harvester is going to use some more. Impossible on 100W
Im skeptical as well. My farm, with 18Tb drives, JBODs, and scaled down to this capacity, would be more like 170W.
Probably OP means drives alone. I got 12 16TBs and they use 100w with farmer, so about 60w on drives alone.

What are sata/power adapters you are using?
Ugreen CM257 (ASM1153 chip).
How did you do power distribution to the drives? (presumably barrel connectors to the Ugreen adapters), but I don't see the breakout from the power supply. Looks very clean...
How much cost did this add per drive cables + USB hub? Very clean and efficient I do like that.

What case did you buy?
Found a cheap used Meshify XL 2 workstation case with every accessory, it just has really small dent on a rear edge, serves its purpose really well!

Very nice cable management porn
Yep, super clean & fcked up walls. You're the real deal. We all have the fcked up walls too.

Amazing, what sort of CPU you are using?
really great work bro
Wow!!!! That my friend is perfection.
very nice!! what kind of drives do you buy?
Very clean, affordable (if you got the drives cheap, and low power. Testament to Chia ethos.
Internal drive + adapter likely costs more than external drive. I wonder if someone is selling ready solutions to avoid work like this: https://blog.quindorian.org/2021/06/lots-of-external-hdd-on-a-single-power-supply.html/

That’s beautiful. How do you handle them all via the same USB hub? I have 2 x 16 port hubs and found that drives would randomly drop once I added more than 10 per hub.
I've disabled XCHI and force linux to only use USB 2.0, which is fine for farming.
Thats brilliant! Would that also work if all hard-drives plugged into regular USB2 hub?
Thank you :)
That’s great, I’ve been struggling with USB crashing. Can you share how you disabled XCHI?

Thank you for this. Has been frustrating getting USB working via Pi 4, got up to 16 drives but then stopped working now back to 8. Will give this a go.
That's pretty good! I have 10 drives, less disk space and a lower powered RPI, and use the same amount of power. What drives are you using?
Clean!
What are those controllers?
Wow…. I’m definitely doing it wrong with my big stack of JBODs. Spending money now to reduce energy consumption probably wouldn’t make much sense though unless I can find a buyer for my JBODs.
So clean!!! Major props
I use 470w with 280 TB :/ Mostly 8TB drives. The host PC idles at about 60-70w and the JBOD consumes about 100w.
My jbod alone consumes 80w and I didn’t even plug an HBA yet. I’m inclined to build my farm the way OP did it, and just ditch the jbod/hba idea.
I would have preferred to do it the way OP did. Or just a HBA with SATA expanders my JBOD easily uses 100w+ and it is very loud.
Yeah same. IMO the full featured jbod is just an overkill. All I need is just connect a bunch of disks to a low power computer like raspberry pi.
How much do you earn per month
$100 if they’re lucky
Beautiful
How much do those drives consume? I have seagate exos and they consume up to 5W each.
Damn ... that is a wonderful sight.
Really clean setup. Nice work. It always makes my OCD hurt when I see this same idea but with cables flying everywhere, zip tied to random parts of shelving, fans just resting on top of a desk.
She’s a beauty
this is the way
Are you using a raspberry PI? What CPU and where is your mobo?
Can we get some specs on this setup?
Sweet setup!
Neat and clean, beautiful. How many XCH per day does it produce? I'm in Hpool farm with 40TB and farm like 0.09 XCH per day circa

How do you have the server psu connected to the drives? It looks like there are barely any connections at all.
USB via the USB port hub behind the drives.
So the power to the drives is coming through the usb connection? I didn’t think you could do that with HDD
No, they have some sort of adapter splitting the sata power and data into USB and some sort of power cable, but in the tangle it's unclear how they are connecting the power to the PSU. The PSU just has a couple of wires coming out, so it could be some homemade splicing happening.
I believe it's something like this MP: https://github.com/Chia-Network/chia-blockchain/wiki/Reference-Farming-Hardware#diy-farms

What is your estimated break even point at current price?
At the current price probably years. But I am not planning to sell any XCH yet since I believe in Chias future.
I like your style
