Amazing setup. I could not follow your explanation (newbie here) and I’m astounishing that you are able to manage everything with a single PSU.
Is it possible that you explain with more pictures, or with more details, how you are manaing those wires?
Currently I’m strugling with PSU voltage in case i want to add more than 6/7 hard drive 3.5 with the same psu and i didnt find any good solution.
Thanks for your help!
How do you sequentially start up each harvester?
Can’t post more pictures, since I rather rarely visit the place in person.
I’ve settled with MeanWell PSU PSPA-1000-12. I’m not an expert here, but MeanWell seems to be high quality company and they provide general purpose PSUs.
That PSUs has 4 positive and 4 negative terminals. I’ve used thick cable (25mm2) that I’ve split on one end to 4 cables (roughly 6mm2 each) and crimped with round/fork connector- I had to buy some workshop tools for that and quite a lot of terminals as well. This lets me connect this thich cable to the PSU. On the other end the cable is connected to the Blue Sea System fuse box. I’ve used round terminals there.
Fuse box has quite few terminals and I’m connecting cables to that using round/fork connectors.
For USB HUBs I’ve bought plenty of cables with 4.8/1.7 connector (fits AmazonBasics 7 port hub). I’ve joined 6 of such cables with one thicker cable 2.5mm2 that is eventually connected to the fuse box (20A fuse).
For 3.5 drives I’m basically using single 2.5mm2 cable with 7 spots with removed isolation - you basically remove isolation (using isolation removal tool) in the furthest spot and it will move it a bit. I’ve joined each such spot with 0.75mm2 cable. Ideally each such spot should be soldered. One the HDD side I have 5.5/2.5 connector with screws where I put the 0.75mm2 wire.
I have central server that manages the entire operation. I have custom software on the server (I’m software developer) that performs such operation. I’m using WoL to start the HP T520 remotely.
Did you used to work in a library 
Kudos! Neat, organized, efficient XCH machine 
Is it hot there? 
Hello Sir,
First of all hats off to the wonderfully organised setup, it’s a charm. Looking carefully I noticed that you have placed the 8 tb Seagate HDD upside down. have you placed them like that on purpose, if so is it better heat dispersion? Thank you. Cheers!!!
Not as organized as others, but managed to squeeze over 750 TiB in here. Gotta buy another server or two to get those disks off that table and get rid of it! Got another 30 TiB sitting out of site hooked up to a Raspberry Pi.
Even more important than the rig, which is well organized with that amount of storages is, How do you manage the conversation with your family regarding the server in front a closet? ahahahahha
The vacuum cleaner is wel hidden 
Not my favorite chore either 
Where is the anti static bag for the nice controller on the rug on the lower right!!!
It’s a 9260. No pass through. Means I don’t give a crap about it lol. I think it came with that most recent 3U I just bought.
Lol. I live in a little town house. Not many options lol.
They don’t mind it. I’ve managed to keep everything relatively quiet. It does get a little toasty in there though when plotting! I guess the girlfriend figures that there are much worse things that I could be out there doing! The hardest thing is keeping a 4 & 6 year old from wanting to press the drive release “buttons” on the drive caddies!!! Lol.
Hello, thanks for your nice comments.
Actually putting the disks in that form is my only option. Horizontal for balance and I like to see the USB wires in front for simplicity at the time to connecting everything and also I need a shorter size USB to the computer behind.
Thank you for your kind reply. I thought you might have done it on purpose to get the temperatures down. As I have placed mine too upside down and by doing so I could see the temperature of my HDD’s going down approx 3 degrees C. You mentioned that you are in cloud engineer, so I thought to ask you if putting upside-down might have a potential benefit. Keep calm and keep farming.
