Homelab upgrade: New Raspberry Pi Cluster rackmount

[@derekjohnson747]

To those of you who don't use CC, you're missing out! Thanks Jeff for going the extra mile and the laughs

[@realcartoongirl]

im cc

[@TheOleHermit]

I would, but I don't have any friends to carbon copy. But, I've been using CC a lot with my MIDI. 😜

[@jakecobelton9876]

What is CC?

[@notfunny3397]

CC is closed captions. It's what most people actually mean when they say subtitles. Respect to the creators who put in proper subtitles.

[@jlwtrading]

I always learn something by watching this KZbin channel. I'm just a beginner with Rpi, but this show showed me where to use rpi-clone - a great little utility which I looked up, and now I know how to use. Thanks, Jeff!

[@JeffGeerling]

rpi-clone is so nice for the case where you just want to move to a new microSD card, switch to SSD, or switch back from SSD to microSD.

[@RIPenemie]

It’s really really good to see you looking so well Jeff. It’s wonderful 🥰❤️😁 Stay well and keep up the amazing videos sir.

[@MarcelHuguenin]

Hope you're doing well Jeff. Great to see more and more Pi-related stuff for professional use coming onto the market .

[@yourpodcastsidekick-cd]

I enjoy how considerate you are of your audience by explaining levels of detail all the way to sponsors. Thank you for putting in that extra effort.

[@psiborg6072]

I think this would be really great for university labs to experiment with clusters. They are high enough quality to hold up for years of use.

[@harrkev]

It might take years to get enough Pi's to put in there.

[@jonathanbuzzard6648]

Not really, much easier and better to keep a bit of your previous cluster for that. Not being x86 is a big issue as lots of software does not work. How do I know this, well my day job is running an HPC system, for a university. Guess you guessed correctly we retained some of our old cluster for this purpose.

[@psiborg6072]

@@jonathanbuzzard6648 interesting info, thanks!

[@cul8terworld]

Why not just create N VMs? You have a virtual cluster then.

[@Marco911]

massive waste of money.

[@charlieglennevansjr]

This is exactly the setup I'm working towards as well. I have 4 Pis in a Kubernetes cluster with SSDs but I'm running them all with the power adapters and in a little acrylic Pi rack. This video hit at the right time!

[@ThePhoenixAscendant]

Love the touch of adding CC to the video. So often I have to use the auto generated CC and it's always hit or miss...

[@MStrickkk]

This rack mount is SO FREAKING COOL! It solves all the issues I would have with every other Pi rackmount I've seen.

[@lmaoroflcopter]

I love those little stanley pen screwdrivers. Just perfect for almost all your electronic needs, it's not as fancy as the ltt, but it's definitely one of the most functional and used additions to my laptop bag. I had no idea the raw hex socket fitted the motherboard standoffs! Mind blown!!!

[@bobthemagicmoose]

Thanks for marking it as sponsored even though they didn't pay you. If only other youtubers realized that the free equipment, early access, and other benefits are essentially payments.

[@JeffGeerling]

KZbin's own description of that 'paid sponsorship' badge says as much. Sadly, the FCC won't ever be able to enforce the rules for the zillions of smaller content creators. I try to both mark it with the 'sponsorship' badge (even if no extra payment) _and_ make it clear my relationship with the company in the video, because honesty/transparency is the only way for viewers to actually make a judgement about the content itself. I also publish my own guidelines here: github.com/geerlingguy/youtube

[@PeteDavisYates]

Great looking product. My only gripe is the USB jumper being left as the green pcb, which against the black enclosure just detracts from the visuals. Will be keeping an eye on this product for future revisions for my own lab

[@stevenchristenson2428]

Yeah that seams like a oversight on the part of the lower PCB designer.. There are pads on the PI that give you USB so they could have just added some more of those pins to interface in that way instead of that jumper. It just looks janky and unprofessional in my opinion.

[@ff1077]

Finally! Some more regular Raspberry Pi model videos! As much as I also like the compute module videos, I have yet to get one, and all I have currently are regular Pi models to use.

[@eugenb9017]

Great to see you're back, hope you're feeling well.

[@peterthill]

To be honest: I stumbled around your vids and NOW it is happen - with this project you gain another follower. So pls keep the good work up 👍

[@lowkeygaming4716]

I really enjoy watching you build clusters of pi because it feels like you're making a mini data center. I also want to build one but I don't have usecase for it 😅

[@awright18]

Every time I see you mention ansible. I'm reminded that is yet another thing I need to learn. This time maybe I"ll take some time and take a look. Love the video, I use a 3D printed pi-rack today as well. I do like this and other options like it a bit better especially the idea of hot swapping them easily. Take care, and see you in the next video!

[@BredihinKA]

8:07 - DNS redundancy is highly desirable. As an option, run PiHole on another raspberry and set up Gravity Sync between them. It made my life very easy. I have one DNS spinning on a virtualization environment, and the second on a separate Raspberry pi.

[@JeffGeerling]

That's likely what I'll do, my plan is to build a new router "someday" (not sure when that day will be), and it will run routing/DHCP and DNS as a 2nd Pi-Hole.

[@edwardallenthree]

Gravity sync? Cool. Looking up. Right now my piholes are not synchronized automatically.

[@SchoolforHackers]

Thanks for the tip on Gravity Sync ...

[@HiltonT69]

I looked at Gravity Sync, then Adguard Home with Adguard Home-Say c, and ultimately moved to an Adguard environment as the syncing was a lot better, and I've been very happy with the result.

[@un1530]

Ah good thing to see you up and running again Jeff. Good news on the blades too cool.

[@KiraSlith]

This is so close to perfectly designed, it just needs a little shove to perfection. The ventilation is a problem yeah, with all 4 under any real load that little box will get hot. BUT a bigger problem in my opinion is the exposed pins on the back of the USB bridge PCB, those have exposed 5v right next to a load of sensitive IO and can easily be shorted together by bumping them with anything conductive, that means any metal, certain kinds of cloth, dust, or even some errant forehead sweat, and those are all known dangers with an active rack, and it only takes 1 good short to kill the USB 3 controller on a Pi4.

[@ryanebigelow]

I can’t wait to see the PXE boot guide when you release the video!

[@JeffGeerling]

It's been a long time coming. Still have some work to do, it's complicated enough that to uncomplicate it for a video takes a lot of extra work!

[@walterwhite2270]

Hey Jeff glad to see you up and around...hope you get better every day!!!

[@vladislavivanov2511]

Another benefit of the proper enclosure is not having to worry about 3d printed plastic being next to electronics. Most filaments burn like napalm

[@kayakMike1000]

I love the smell of napalm It Smells like victory.

It really depends on the filament, but generally they are not as flammable as you think. kzbin.info/www/bejne/l2jPYXSXrtislZo

[@theglowcloud2215]

Well yeah, don't print a 1U enclosure out of PLA. ASA has a heat deflection temperature of like 85-105C. If the air inside your server is above 80C, you've got much larger problems.

[@vladislavivanov2511]

Melting / deflecting is one problem but what I meant is that I don't want an exploding capacitor or a shorted component heating up a PCB trace to ignite the plastic. Industrial electronic enclosures are made from fire retar dant plastic for that reason

[@fredrik_g]

Love the transparency, and integrity you display - most KZbinrs have something to live up to there!

Thank you for pointing out that the LTT screwdriver needs a bit that can work with board standoffs. The exposed pins on the USB-USB adapter makes me extremely uncomfortable. I want to just reach out and put a piece of electrical tape over it.

[@JeffGeerling]

Maybe it could be a challenge in the coming months. How many times can I service the rack without shorting a connection on the exposed plugs :D

[@deanlawson6880]

Very cool rack device for the Pi setups! I like this alot! Thanks for this Jeff. Nicely done!

[@the_beefy1986]

You look like you're doing better Jeff; I hope you are, and from someone with digestive issues, I hope you're also *feeling* better. :) On a technical note, it would be nice if a future revision of the standard Pi included pin headers for USB so that various add-on boards could interface with the USB bus internally versus having to have male-to-male dongles on the outside.

[@JeffGeerling]

I'm hopeful there will be some additional interface to get more IO, more easily, on the next model B boards. They are so great for so many things, but they always look a bit odd when used in any non-hobby scenario.

[@AudreyRobinel]

@@JeffGeerling I think there should be no such additions on the next model B, but rather a model C for such things, so that the price won't be such a constraint. Pi model B is meant to be as it is now while maintaining a price low enough to tinkerers, education, etc. But i think us enthusiasts (i am also an educators, so i understand the price constraint well) wouldn't mind paying more to have some extra stuff. Also, model C could hapily break the form factor. Like a bit larger, with all the IO on the same side, a sata interface and/or NVME, and why not some PCIE connectivity (even trough NVME). I mean, i like the pi form factor, but it is quite limiting in some applications. We have 0 and CM4 for compact, A is dead for now, B for general use while remaining cheap, and C could be more power user oriented. But perhaps the model C's role is already fullfilled by the CM4 + the right carrier board. Perhaps the pi foundation should just release more carrier boards? I hope the current carrier board form factor is not what the one for the CM5 MUST be, that they are not bound by it!

[@JeffGeerling]

@@AudreyRobinel True... maybe model B for hobby, model C for power users/desktop, and CM for embedded/industrial.

[@chublez]

I agree so many of those male to male U's put out a ton of RFI also. My biggest complaint with the Pi4B though has been the 2 micro HDMI ports. I don't know anyone that uses dual display with a Pi, most of the Pi's I know about run headless. The ones I know of and have hooked to displays all the junky adapters cause more trouble than a second HDMI could possibly be worth. Honestly with the prices right now and the annoyance of the form factor and micro HDMI's unless a Pi is absolutely necessary I use and recommend used 1L office PCs. Personally partial to the Lenovo M93p right now they go for about the same as a Pi4B by the time you get all the kit for it, More horse power, More ports, takes real SATA drives, DP standard which has good adapters to HDMI but if you look you can find em with a secondary HDMI port already optioned. Only drawback are they are a bit bigger and idle consumption is a bit more but you get a more powerful machine for it. However with Proxmox on one with an i5 it could take the place of several Pi's making the power use a wash so long as x86 is fine for what you're doing.

I'm waiting impatiently for the PXE pi poject!!!! It’s one of that ideas I dreamed of for years, but never attended to study enough to realized to (I have prioritized other projects).

[@LunchBokth]

Love the videos! Here’s an idea: setup a bunch of micro sd cards in raid and write a bunch to it until something fails. I bet they last longer than we’d think. Would also be interesting to see performance over time and how hot they get and such.

[@NeilHyndman]

I liked this product, the Pi Cluster Rackmount Kit. I'm not sure the price is in the right ballpark - it seems a little steep. I would definitely consider this, as long as the following was done: (A) all screw holes were properly aligned - when I purchase a product like this, I'm paying for perfection. (B) There needs to be much better ventilation and at least an option to add two fans. By watching this video, I would say this rackmount unit is in the beta phase and needs some work. If they clean it up, I would definitely buy it at a lower (reasonable) price point. Thanks for the video - it was very well done!

[@EpicSoftworks]

Wow. That is really awesome! It also seems like a lot of fun to have something like this in your cluster. Lots of tinkering and all the technology to learn from. I have quite some Pi's lying around, might consider getting an enclosure like that in the future.

[@kastorcaster]

I have one of the other pi rack configurations from uctronics, the one that holds them vertically with base plates. I would strongly recommend avoiding that version specifically, as the screw holes for mounting the pis get deformed after a couple uses.

[@UCTRONICS]

Please contact us, and we can do the replacement for you!

[@SchoolforHackers]

@@UCTRONICS Now that’s some great customer service!

[@UCTRONICS]

We update our new designs with captive screws now, making them easy to mount, we don't have such potential issues anymore.

[@ronknight1010]

Pretty cool. A quick way to improve ventilation may be to drill holes and mount fans in the back of the enclosure for the pi's. Provided theirs enough space

[@joeg3950]

Great content! As soon as you showed the enclosure, I had the same thought about ventilation. Keep having fun

[@springsenior2006]

Good luck with UTronics. I purchased this about a year ago and within a month the POE power supply started dropping voltage to the point it will no longer power the Pi. The cooling fans also die very quickly. After 2 weeks one of the fan's bearings failed. Swapped it and got another 3 weeks out of the new one. I tried contacting them and admittedly they were helpful and sent me replacements but after the second RMA I gave up. After 3 months or so I scrapped the whole thing entirely.

[@JeffGeerling]

This unit doesn't come with any PoE power supply, I'm using Raspberry Pi's own PoE HATs with it. They do make a ton of different products though, maybe one of the other models has an issue with heat or power. So far it hasn't been an issue with the SATA HAT after a few days at least.

[@UCTRONICS]

Hi Dustin Thompson, the default POE HAT is 802.3af which can only source 5V/2.5A power and is also impacted by the POE switch capacity, RJ45 cable quality, and on-device peripherals (USB hard drive for example). All of these factors might cause low voltage caution signs. And we keep improving UCtronics products according to customers' feedback, we will release a POE+ HAT very soon to support 5V/4A, keep tuned.

[@ronaldmullins8221]

This is neat, really like the power button and screen, not to mention access to almost all ports and SD card on the front, but I rather use up 2Us of rack space for vertical Pis than 1U of just four horizontal. Feel like you can get more density with that than this, even with all the extra stuff thrown in

[@TheJonathanc82]

Great to see you looking well Jeff! I am so tempted to pull the trigger and buy one of these. I’m itching for a new project.

[@Doesntcompute2k]

I enjoyed this new video. I'm running two of these (5-bay) with the 12-bay 3u also. Their SSD mounting adapter is kinda pricy for that 12-bay (12 x $20). But you don't have to boot off of SDCards. You can boot from (cheap?) 120/240GB SSD. Which somehow I had 20 new of for some weird reason. I love your network Internet-Pi scripting, BTW. I removed the Pi-Hole and such and modified it a little to be a small NMS. I like being notified when my network goes down or slows down. :) Keep up the great work, Jeff!

They all run under Ubuntu 20.04 except the home assistant box. Currently the all back up to a local Synology box then replicate backup to the cloud. I have been looking for an affordable case this looks great but probably a bit too expensive for me just now. I am looking at migrating the Ubuntu boxes to pxe boot from the Synology this will help me sleep better at night, I have piloted one box successfully and am looking to start moving the hosts over this next weekend. Thank you, over the years you have been a real inspiration to me and my ip project. When I started with a pi 2 and asterisk test bench.

[@kevinshumaker3753]

I really like the ability to insert the Pi sandwich as hot swap-able. Very nice. I would like to see some ventilation on the top, and air flow for edge to edge with a fan or 3... $300 isn't bad for the extra capabilities the trays give you.

[@chublez]

Sounds like they where responsive to his suggestion. Hopefully they'll revise the design. Until then I bet just taking the case to the drill press and putting a pattern of holes in it for passive cooling would mostly fix it and it wouldn't be to hard to mod in a 40mm fan or 4 if wanted/needed.

The only down side to all this projects requiring more and more raspberry Pies is, that the Raspberry Pi Foundation isn't able to produce them as cheap and as quickly as the market demands them :/

[@its_taki]

I dont know anything about raspberry pies 😂😂😂 and still Watch the whole video. Amazing project man!

[@TESFox]

Still watching this, but I had to pause for a laugh when you introduced the new enclosure. I actually have the non-pro version of this kit and it's worked out pretty well though I've not finished setting it up as yet, I still need to get a PoE switch, shorter cables, mount the last 2 pis, and get my pis all configured. One note I've had thus far is it's worth considering replacing the fans that the PoE HATs come with, because they've been kind of rattley/noisy IME. Quick edit: If you've not heard of them, you might want to look into RackStuds instead of the traditional cage nut & bolt mounting. I've really enjoyed using them in my racks, completely toolless and very secure.

[@JeffGeerling]

I've considered using Rack Studs, and they do seem great for smaller devices like this... but since I like just standardizing on one thing, everywhere, I settled on some decent cage nuts and am sticking with the screws-some of the equipment in the rack is over 100 lbs and I can't trust the studs with that :) But who knows? I do like the idea of using them for network equipment which is often a bit lighter.

[@TESFox]

@@JeffGeerling I feel you there! I use them on all my network equipment, I'm trying to recall what I've done with my servers so far, I think I've not used them there only because most of the (all second hand) servers I have came with toolless rails. That said, I installed the full shelf in the bottom of my 48U rack that's supposed to hold my UPS (which is also TBD) using the included bolts and cage nuts. That said, my newer wall mounted rack for my networking kit is 100% rack studs :)

[@Chopper087]

Happy to see your getting better! Thank you for the video, your content is always top of the line and can lear something from it! You inspire me to get my hands ditry with raspberry jam ;) :D

[@wisenber]

What part is actually hot swapable? I have drives that allow me to remove and replace members of an array without downing my server or appliance. I have redundant power supplies that will let me remove and replace a power supply without downing the server. All I'm seeing with this is a tray that allows you to power off a unit and remove it with all services ceasing during the process. Regarding the heat, you might try tapping the holes for fans on each side and see if the holes alone offer enough air movement without installing any fan first. Neat project. I have been relying on more virtualization than dedicated hardware for various services.

[@charlesschreffler5111]

for a home lab setup i recommend rack studs they are awesome

[@friedrich1277]

Beside the already mentioned temperature and ventilation problems, i think they should improve the IO shield of the PI (e.g. the huge gap above the ethernet jack) and provide these USB to USB adapters with black PCBs before i consider buying it...

[@squelchstuff]

An interesting solution and appears to be well conceived. Concerning the misalignment of the holes, it seems to me that the order of assembly is a little off. If I understand correctly, once the SSD is plugged into the carrier board, any tolerance allowances start to accumulate leading to the misalignment as everything is tightened. Perhaps the SSD should be loosely mounted onto the baseplate first, and then the PCB plugged onto the SSD? This should allow enough play to then align the PCB mounting screws before cinching everything down. It's good to see you firing on all cylinders again Jeff.

[@JeffGeerling]

Ah, that could be possible, I was 'loosely' following the assembly guide ;)

[@QuentinStephens]

Good to see you up and about. You touched on SD cards: one thing I learned from dashcams is that you need to be using High Endurance SD cards.

[@shalamigri]

It may be wise @ 5:50 to let viewers know how to make that ribbon cable connection. A person new to that type won't know that you have to pull the clip on the socket out before the put the cable in. You then push it back in place to secure the cable. I've seen more than a few videos of people making that connection, but no one ever points that out.

[@TheAnthoy101]

Great video!! Big fan. I recommend trying something called a Raspikey - they fit in the sd card slot but uses EMMC - a lot more reliable than a SD card, we have replaced all SD cards in our pi with these Raspi keys at work and haven’t had trouble since.

[@akxdev]

Jeff, I'd be interested in learning more about your career path. I'm in L2 support now, with a deep interest/focus in software development, and you seem to have a pretty holistic view of the modern tech landscape. I'm interested to hear more about how you got to where you are.

[@theglowcloud2215]

I don't understand why UCTRONICS didn't make any consideration for cooling in that case. And their answer to whether they'll revise the design is "lol idk". Amazing.

[@waaromzomoeilijk1473]

For now I'm going to try one intake on the side, and see if that can move enough air through all the gaps in the front of the case to get the Pis back down to the 50s.

Speaking of those monoprice ultra thin patch cat6 cables, they are good for up to 30w. I run Panasonic PTZ cameras on them all the time and they are POE+ and draw about 28 watts.

The OLEDs look super useful!

Inbetween us smartalerks on the super nerdy side: How is this a cluster? You are running several computers that are tightly connected, if the stickers are correct. A cluster would be to turn them into one computer and running the software on top. So, clusters are only as fast as the nods, which limits the overall performance using the berries. As soon someone is having a collection of especially these sweet tinies, it all for a sudden does make sense to use them all more efficiently ba creating a cluster over a connected set. Basically, from getting into building dedicated berry boxes that do one thing and one thing only, to having possibly a dozent all over the nerd castle that do all one thing each yet are well connected in a better sub-net, the next step is to turn them all in a cluster berry, let's say a beowulf-bush, that uses the resources more efficiently of each part, because sharing is caring. There are several well documented set up designs out including full libraries, such as Beowulf cluster architectures. #cyberpunkcoltoure PS:You cannot follow, you ain no our level of nerd. Go learn!

Dual 40mm on one end and some vent holes on the other end would be best for that surely. Even close off the holes on the rear so that it's a fully flow through design. Not sure why it would have been missed by the manufacturer in the first place.
