More bottlenecks than a Coca Cola factory.

60 HDDs in RAID 0 is the definition of "all gas no brakes"

I had this colleague who told this story: I had boss who did not understand anything about computer or electronics. When ever I was trouble shooting something he would come and watch over my shoulder and comment "Have you checked the power?" This was very annoying as he did not understand anything. What made it doubly annoying that his advice was spot on so many times. Check the power!!

Pushing the limits of "hackey" tech is what most hardware and software engineers should be shooting for. Very well done. Kudos to 45 Drives!

A petabyte and a raspberry pi, the crossover we didn’t know we needed. This is sick.

the PetaPi seems like a winner, I can only imagine the folks at 45 drives watching this with a mix of awe and horror.

This is a bonkers crazy setup. It's so mad I just had to watch, 100%. Kudos to you for getting it to work at all. Your persistence is inspiring.

Even though the idea is crazy, Jeff knows his craft. The tips at time 09:00 on how to select hard drives for the task are priceless!

"I was going to unbox this on camera but Fedex already did" As someone who's had multiple expensive items destroyed by Fedex and actively avoids doing business with companies that ship with them, I felt that...

Do I need a petabyte of storage? No. Would I mount one in my rack? Yes.

Jeff you never cease to deliver, you're an absolute legend, great video!!

Fascinating! A lot of work! The issue it seems is having to tether to the hard-disk through a band shared with other drives, rather than universal. There is a technique where using data-points written to each hard-drive mathematical computations can rewrite and measure the data for inference machiningly- without even using the shared io-bus anymore! You’d see a slowdown in computation monologue but all speed ahead on as many drives as you want!

I think i heard Seagate in the US having a heart attack watching drives being juggled. I live in Taiwan.

How about one controller to one pi, then stripe 4 pis together, that should increase the throughput and scale down the issue to a more managable chunk, and still a pi project.

As someone who is about to endeavor on a new NAS project, this was a fun watch! Thanks!

It's impressive that this works at all.

Woah.

I always like to think that every time Jeff publishes a new video, the raspberry pi design team feels a disturbance in the force.

My God! 20TB 60HDD I never dreamed of such a volume

This is an awesome project. Makes me wanna build a large storage server.

Linus would be proud

I hope LTT sees this. Great stuff as always, Jeff!

You are an absolute madman and I'm rooting for you the whole way

This tutorial helped me so much!! Thanks!

1942: "We need to figure out a solution to digitally store dozens of bytes at a time. Vaccuum tubes, maybe? This is going to cost us millions, but it will be worth it to finally have accurate artillery range tables!" 2022: "I'm going to hook up this petabyte of data storage to this cheap single board computer!"

You tried all the things I wanted to see. You know your audience!

Jeff another wonderful video. Keep up the great work.

Well, pairing €20.000 - €24.000 worth of drives with a 100 dollar raspberry seemed like a solid plan to start with. Having it run a 1pb raid0 config while hosting that storage seems like a task made for this little arm processor 😂 Nice to see you try out such extreme things with the raspberry😀

Oh my goodness, that juggling of those drives.😳

I saw you posted some on the homelab subreddit last week, THIS is what you were hiding from us?? What a fun idea. Can't wait to see your next project!

Yet another absurd carage setup. Just love it!

Thanks for this idea to store my stuff.

Glad to see Red Shirt Jeff back. I was wondering what happened to him. Geez, your projects are soooo extreme and cutting edge. Your troubleshooting processes are very informative and helpful to your viewers, who otherwise wouldn't have a clue where to look. We never see that on "How to" setup videos, where everything just automagically works. BTW, I recently used Styrofoam to separate 2 prototype boards while testing them out. It got hotter than expected and the foam sagged, allowing the power rail of one board to touch the other board, which fried as soon as I powered up the following morning. Don't try this at home, folks. Cardboard insulation good. Styrofoam bad. Thanks for sharing Jeff. I'm fully confident that you'll get your bandwidth up on the 60 HDD RAID. Looks to me like you're already nearly there. Instead of installing it inside a server rack, perhaps a locked cage would be a better idea to protect it from Red Shirt Jeff. 😎

Jeff Geerling: My storage setup registers on the Richter Scale

Awesome video & project!

This showed up in my recommendations. I have no clue what happened here and I know nothing about data managment or IT in general. But I watched it to the end not realizing that this vid is 22 minutes long 😅good content 9/10

When I first saw the title I figured this would be one of your massive multiprocessor/multi-Pi projects combined with a massive amount of storage. Something closer to 20 TB per Raspberry Pi. At 60 Drives and 60 Raspberry Pi's, that would still be way beyond any normal homebrew project.

Hey Jeff, I’ve been using your ansible roles for almost 10 years. Love seeing you around HN and the other traps, great to see your KZfaq channel is doing so well. Very cool projects!

I'M SO INTERESTED IN THIS PETABYTE THING

Be careful with those sata to molex adapters...they are prone to fires!

Jeff, you have carved yourself a niche channel in an overcrowded tech community, taking the Pi to new heights in every video. Keep it up. Loving every video. I'm left astounded on the Pi's capabilities and untapped potential.

I think Arthur C Clarke hypothesized that this would be enough to store a few people's minds into it

OK, this is the kind of cool content I like seeing appear on my birthday! (even if I didn't see it until 5 days later.) Just ONE of those drives is more storage than everything in my house, and I do Unixy networky stuff for a living. :)

Maybe the CABD order is like the firing sequence of a 4-cylinder petrol engine lol 🤔

Peta-Pi go BRRRRR Im genuinely surprised this worked, very impressive. As for what to do with it, a video on downloading/hosting a local copy of Wikipedia would be pretty cool.

Very interesting watching "The PP Project"! :D

This guy is the only human capable of winning in a debate with Data from star trek.

Many Pi’s running something like Minio might allow for some interesting single box hardware redundancy. Also might be able to get over the 1Gb limitation since you’d have many pi’s each with their own 1Gb connections.

This is amazing. Good job charming 45drives into sending the case! They must be Red Shirt fans 🤣

As an HDD engineer usually drives are built to compensate for vibration due to certain fan RPMs. Especially if we have a big customer we'll optimize things for the frequencies of vibration in their trays.

The slow storage movement. Bytes aged to perfection, not for those in a hurry but for folks who appreciate a good long wait for quality unbalanced spectacle in design.

My NAS is a pi4 with a desoldered USB chip to expose the PCIe bus. It's connected to a PCIe switch(to improve transmission and prevent crashes) and then to a cheap ASMedia SATA controller. The kernel is also patched to force PCIe gen 1 to prevent crashes(this is probably the same thing that happened to you in the video btw). PCIe gen1 is still faster than gigabit so it doesn't matter. Over samba or NFS I can get the full gigabit speed even on large data transfers so no bottlenecks there. Would I recommend this setup? no. Does it work? hell yeah (longest uptime was like 90 days or something and then a power outage killed it, I need to get(or more likely make) a UPS, I know). If anyone wants photos lmk

60x USB-connected HDDs... I'm telling you, a missed opportunity :D

Hey! 45 Drives is here in my home town!

Absolutely fascinating and completely, totally barmy! What an immense amount of work you obviously put in to this - research, sweet talking 45Drives, research, RAID solutions, research, talking to 45Drives techs, research, etc. I am *extremely* impressed, both by you AND by 45Drives for their courage! And my abiding thought? "Chassis" is pronounced "shassey", not "chassey"! Pfft! So I looked up chassis in Cambridge Dictionary to back my obviously accurate opinion and ... well, blow me, North Americans really do say "chassey"! Every day is a learning day! Pedantry isn't good

Well Jeff, one thing's for sure, if you and others aren't pushing the pi to bleed on the edge, no progress will ever be made in this direction. I'm not sure what kind of useful stuff this direction will yield, but it surely will yield something. Keep on pushing ya madlad!

It was only about time that the new storage measurement of reference was going to be the petapite... I'll show myself out :D

Jeff, I'm catching up with thx, since I've admired your ability for a while. I am an old geek and you do magic. Reminds me of my S-100 days with CromixOS.

Amazing content as always, keep up the great work!

It almost hurts to watch the board being removed. I've been wishing for a storeage like this for decades. Still a very interesting project.

Ripps out high end setup for a PI! You Monster! Though a Fun Project to play with a pi, maybe in the future with a PI 14 hope you enjoy your new Perabyte Server

Dude can fit 0.01% of the internet on this damn thing. Insane.

One thing I saw you doing when wiring up the NAS was that you connected the molex adapters to two sata power connectors on the same line. If the psu has another line, try connecting to that, as each line can draw a limited amount of current and there might be an issue there. Then again, the issue might be anywhere else but that's a thing you can easily try

"I was thinking about unboxing it on camera but fedex already did". Best punchline :'-)

Yay! Tiny computers doing huge things!!! 🔥🔥🔥

this is amazing

Even before doing a raid or zfs test; I’d have run a single drive test (either benchmark or simple linear read/write). Loop that 60 times and see success. Then repeat with two drives in parallel and loop 30 times. Redo with three in parallel 20 times, etc etc. When you start seeing failures you really will see the cause-effect point. There is technically no reason why this won’t work with 60 drives - if you ignore performance. Any bugs that are exposed that can be fixed will simply improve the base users world. This is an awesome test that pushes the RPi and kernel to the limit. Making this work at that limit helps all of us just running one drive. Plus, the errors you saw, as bad as they were, should somehow restart the drive (without a reboot).

Jeff doesn't have the word "why" in his vocabulary :) (Just kidding, things like this are fun, which is "why" enough for me).

Hu, I know that modern cases have that 1 stud so you can place your motherboard in on the stud which makes it easier to align the rest of the screws, but even then every motherboard I have installed has had 8 - 9 screw holes, sometimes there is a heatsink or something in the way of having all 9 screw holes, but 8 is the minium I have seen, this is only for full ATX though not ITX / mATX.

When you're testing tech and it registers on a seismometer, you've accomplished something.

i was guessing and hoping this was the project in progress when i saw the rack update video :D

I have smaller versions of those EXOS drives. >200 drives, over the past 5 years, I’ve had 4 failures. 3 covered under RMA. 1 had just expired.

I just completed a 24 X 18T build that's almost 1/2 PB. I bought the drives a few at a time all Segate recertified it seems to be the sweet spot in price for me. I had to upgrade and rebuild things several times. Your video was just like my experience switching OS, FS, etc. I had endless drives/arrays just dropping out, mostly on startup. I tried Fedora, Centos, Open Suse, Suse JeOs, and Ubuntu Server all let me down for one reason or another. I tried them with various shares, raid arrays and file systems; plus not all would run my app. I ultimately got it working with Ubuntu workstation and the Ubuntu share - no samba. I'm not happy with ZFS. I had to kill the swap and add more RAM (which meant a new motherboard) to keep ZFS cache from crashing. I solved the dropouts problem by putting the drives really close to the host board and using short/expensive data cables that are all the same length. I'm using a very old Athlon FX-8300 8 core and 64 gig of Ram. I found a great last generation Adaptec 52445 raid card new old stock. I had to install 2 power supplies and rewire one to all molex to get enough amperage on the 5 volt rail. New 1200 watt supplies have plenty of 12v but almost no 5v power. I also upgraded to 2.5 gbps network card. The write speed is NOT stellar. With Raid0 it goes real fast at first 450mbps filling all that cache, but slows down to about 150mbps. With a single JBOD I only get 130mbps, two drives at the same time still go 130 each, and I can transfer to 4 drives at the same time before it bogs down the network and write speed drops to 70 each drive or 280 total. I already got 4 sas expanders and plan to continue adding drives (and power supplies) up to 2.5 PB. My box is an old IBM 2401 tape drive converted to rack space. I yell at the You Tube screen, not my computers. That's not true I also yell at my computer at work (it's windows).

Super Projekt !

**CM4:** Hey Jeff! What are we going to do today? **Jeff:** You will handle 60 enterprise grade hard drives. **CM4:** Oof

45drives marketing team is on a roll

oh man juggling those hard drives broke my heart

I have a Pi running RAID1 with 2 External SSDs and on times I have to reboot as it seems to forget that the disk exists. That's Pi 4 and Samba and a Window share. So to get as far as you did its amazing.

As a St. Vincent fan, I'm calling it "Pietabyte" whether anybody else does or not.

I'd almost be interested in seeing each raid card assigned to 1 PI and then them clustered together.

The real impressive thing ist that he was able to get a pi compute module 4 I am trying to find one now for almost a year but the only place I even found one listed was on Amazon in the us, it is sold out since then, here in europe I did not even find a seller who listed it

Jeff - I mourn you missed seizing the opportunity to officially name this The Pi-tabyte Project - a portmanteau teed-up for a long drive, but you duffed it, lol. - great vid, keep 'em coming, I'm having a grand time doing some of your projects. Cheers.

How many times did you recompile the kernel?

Would love to see this with a RISC V processor

The linus video is literally in the other tab on opera. I was bouta watch it next.

You gotta admire a guy who takes $50k worth of server and... plops a Raspberry Pi in it. Brave and crazy. :)

If lsblk starts to run out of letters and shows drives as "sdaa, sdab, sdac" etc. you know you have a data hoarding problem.

Next step: 3.14PB on a PI

Integrating a Pi compute module with Ethernet into each hard drive can make scaling easier. It lets each drive connect to a network independently, simplifying data handling in big storage setups.

Love to see how a cluster would handle the drives

I would really like to see you build a cluster based file system like gluster or ceph, run that on a pi cluster with 2 to 4 drives per pi, then show performance

They must really trust you to borrow $35k+ worth of disks

You had me @ hard drives. *giggle* Subscribed.

1:52 I remember when people were saying that about the terabyte. Technology is crazy.

PetaPI sounds nice!

"I grabbed a small piece of cardboard to insulate the boards from each other. At least temporarily." Yeah. Sure. I think red shirt Jeff was trying the break back into the room.

*happy linus noises*

I am afraid someone addicted to this work is called a petaphile person! 😱 But great, that there are people doing these kind of projects!

I built my first datahoarder set up using nothing but 8tb SSDs XD a whole bunch of them. solves the issues of "spinning" in an easy way

it’s a shame you didn’t call it “PetaPi”
