Turing Pi's shaking things up with their new RK1. It's 5x faster than the Pi CM4.
But is it worth the price? Dive into my test results, then we'll rack up two SBC clusters: 6 Pi CM4s on the DeskPi Super6c cluster board, and 4 Turing Pi RK1s in the Turing Pi 2.

"All's well that ends in "Not A Fire"" - a motto to live by.
This is my new favorite quote
Jeff, Thank you for your honesty in who sent you what and how things were paid for. That’s very refreshing in this space and shows you value your audience
It's not even legal to _not_ disclose things. Sadly, many creators aren't up-front about where they get things. Honesty's the best policy... and the best way to ensure the FTC doesn't have to get involved haha.
My wallet wishes I had never discovered your channel ... keep up the great coverage of your SBC adventures, you play in the same space I'm interested in.
“I don’t need a cluster”
“What would I use it for”
“It’s just gonna be running some bullshit”
I so really want one
This is the way.
@@JeffGeerling Why not walk both ways?
First, I completely agree with you. I think this is amazing, just to learn how to build an HPC System, and to see how it works.
I'm in that boat! I have quite a few Libre Computers and Pis, but also small PCs sitting around waiting for projects, while also having a large NAS which sits on top of a Dell Poweredge... The NAS gets use very very regularly, but not all the SBCs or the Dell.
But it will run.... whatever.
As in, nothing you want to do.
I'll stick to my 7950x.
I would be more interested in a lower powered NAS board with just the 4 nvme drives on it or better, loaded with SATA ports.
Man i really hope that Raspberry Pi prices comes down to a reasonable level, so that us enthusiast can do stuff like these
It won't. But I do recommend considering getting it either used or older gen like Raspberry Pi 3 for example which is lot cheaper than Pi 4 or 5, especially if you don't need the performance of those.
Pi 3 or Pi 4 (or even Zero 2W) are probably the sweet spot for value in the Pi lineup right now.
If they release a 2GB Pi 5 for $40, that would be a great value.
appears to be heading in the right direction. :)
@@JeffGeerling That's be like putting a v4 in an old muscle car. We all know that we don't build these things because we need them. We build them because we NEED them
> corpo enshitification enters the chat
this stuff does not make sense when for this price you can buy 3-5 mini pc with 8 core ryzen cpus. you don't have to deal with arm specific software and the performance are 10 times faster.
Rule of cool means this is better
Yo, Only Fans reveal at 11:12!
That would be one scary channel ;-)
I always snicker when I see the "Only Fans" container.
When my son was in cub scouts, he sold popcorn like all the scouts did. We borrowed a wagon to put the popcorn in, and found a cardboard box that fit perfectly! As I was walking behind him I realized that we'd have to ditch the cardboard box. It was one that we got at the local library book sale (They were selling unpopular books to make room for more books.) Written across the back of the box someone wrote "ADULT BOOKS" in large letters. That phrase has a completely different meaning outside of libraries. Lol!
That rockship kicks butt, I can tell, I have a NanoPC-T6 powered by that baby, it ROCKS!
The RK1 boards are crazy fast! I have two of these TuringPi 2 boards, running 2 RK1s and 2 CM4s each. A sort of P-module, E-module configuration. 92GB of RAM and 82 GHz of CPU. I use Hashicorp Nomad to orchestrate tasks using a combination of the Docker and Exec drivers. Ceph to manage the persistent volumes. Soon I'll be able to retire my power-hungry my Dell R710s in favor of a system that draws < 200W. Couldn't be happier with the results!
Really seems like the Turing Pi board could benefit from having a switch chip. Even if you still only had 1 Gb or 2.5 Gb connectivity to the external network, having a 40/80Gb switching fabric between nodes would make something like Ceph internal replication or any node to node comms in the cluster much better. Of course, having a 10 Gb SFP+ would also be ideal, since so much 10 Gb fiber gear is plummeting in price these days, and might obsolete the need for finding another big chip and traces on the board, so that might the smarter play.
I do hope they do a Turing Pi 3, where they maybe bump the price a little, but include some features that will let the board really go all-out on performance.
The problem is as the price of the board sneaks past $200, $300, or more, the audience gets even more limited :(
@@JeffGeerling I hear you, but I think this space could do with some better comms around what makes sense and what you _can_ do with these platforms. Like, a 4 node cluster on the Turing Pi 2 at $1500 does not make sense for most home lab operators and especially not the folks running single purpose GPIO heavy configs, but $1500-2000 for a 4 node Ceph backed lightweight k8s platform with a slough of groupware appliance containers is a stellar HA homelab / business server in a single box. For the load of businesses I know trying to de-SaaS their OpEx while still looking for a reliable solution, this is barking up the right tree for sure.
Really love the screen time during installation and configuration so didactic!!
Break out the soldering iron and swap the direction those power leads exit the PSU board. No more fan-blade jeopardy, no more stressing of the board connector.
True. May do that before I move the mini rack into its final location.
As soon as you said pod was pending and you were using nfs I said to my self "nfs-common". Great video!
Haha if you know, you know. Usually you go down every other avenue and then the 100th google search you get a path that leads to a solution.
I got lucky in this case and skipped the first 99 dead ends!
@@JeffGeerling I've integrated that into my playbooks because Longhorn Storage Class uses it. Took me a while to figure that one out!
Excellent! Thanks for sharing. Looking forward to the new base board with 10GbE.
Thank you for showing the debugging steps with the cluster, including how to see which pod had stalled and finding error logs using "describe". You can watch 100 happy path tutorials without ever seeing these things.
Thanks for all your hard work, Jeff.
I have one of these, and it is spectacular! I couldn't afford to get 4x of the 32gb nodes, but I have two of em. They are heckin nice.
It is nice to have x86-level performance in the same power footprint as a Pi!
These cluster boards keep getting cooler and cooler. Not sure what i would do with one but it would be cool to play with.
I've been using the turingpi 2 with 3x RK1's for a few weeks, and really enjoying it.
Ive been managing it using the Ansible for DevOps and Ansible for Kubernetes books you put out, so many thanks for that!
So glad I could help! Reminds me I need to get around to updating those books again...
Thanks for the mini-rack link. I've been looking for something like this for a while, thinking I was just not looking in the right place. Great for a mini home lab.
Letting red shirt Jeff in to the studio seems reckless.
I just like how it looks, a compact blinkenlights thingy. So cool.
Heh, I need to make a Mini ITX board with just tons of little LEDs around random circuits and chips, that blink in random patterns. The Blinkenlights ITX Board.
@@JeffGeerling Jeff, I'm not gonna lie, but I even bought the IKEA "OBEGRÄNSAD" just to have more blinkenlights in my room. I'm a huge fan of the Connection Machine's by Thinking Machines corporation; even went to NYC just to see the CM-5 at the MoMA. I love the thought process behind it; to give the machines a visual representation of the computation going on as if the black box is thoughtful. I have a few of books and saved YT videos about it too. There's some other pure blinkenlight projects but I couldn't afford them. But I've basically built my own homelab around maximizing the lighting. I was sad to even leave my X79 DDR3 era boards when I upgraded because Crucial's Ballistix Tracer DDR3 were the only RAM kits with true electrically driven LEDS instead of pure software. Made quite a show. Wish you could see my setup, lol.
The 32GB Turing is still less than the price to upgrade to 32GB Ram in a Mac.
Ouch.
So true it hurts!
This rack is a master piece of engineering for home datacenters. 🙂 A little UPS would be indeed amazing. Whoever creates it, shut up and take my money! 😀
The Rackmate T1 in this video is awesome!
Free tip: Don't shake and wave you hands when you are holding something we are trying to see. Very common on RUclips but you can beat it. I did for teaching.
Solid advice 👌
Love these tiny videos. As someone who does Van Life traveling full time in my van, I’m always looking for ways to run NAS and cluster solutions in a compact “portable” way. Especially love it when you can run on 12v, 24v, or 48v DC.
This thing is sooo cool. I stopped running a homelab or server for my house because of power consumption. This setup is making me rethink that. I could do crazy stuff with one of these boards.
Like what ?
Red shirt seems calm in this video.
Practically, you don't need an SBC cluster. Single CPU x86 machine will be faster, and more important, easier to support.
So performance comparison between different SBC cluster does not have a practical meaning.
But it is still fun!
I think you forgot that the main point of this was how power-efficient it was for the performance.
@@xanderplayz3446 Modern x86 will be more power efficient than a cluster of SBCs.
its good for 24/7 use at home without using much electricity. I too have x86 based ones and they break the bank. btw did you know the orange pi 5 rk3588 is so much cheaper than the best x86 SBC for the same performance? it matches the intel N200 CPU in performance, thats how fast the rk3588 is. It beats intel in some things but loses in anything avx.
@@Lincos321what would you use with x86 as a replacement ?
That little mini rack thingy is rather neat. I wonder if one could make a small easy to move server with a rack for compute, a rack for storage, a switch, and if there is such thing, a UPS.
Simply AMAZING !!!
I wonder how it compares to a Milkv pioneer, double the cores, same memory, not a cluster but a "desktop", it does have 10G eth (x2) and NVME.
It's less than double the price, for double the cores and the same amount of ram but probably faster as it is all in one place. No NPU on the pioneer, but it does have pci-express ports so you can add a large video card if the drivers support it, and if you upgrade the power supply.
I absolutely loved the 10 inch rack idea, this is new to me. I have a (official status pending) RISC-V lab in Costa Rica, with a bunch of licheepi4a, vision five I&II, beagleV, mangopi, etc, etc. I think the milkv pioneer is mini-itx, so it would be cool to fit in all of the lab in this rack. It's a bit pricey, but would look and function way nice than what I have right now.
Brought to you by the Pi Cluster King!
I don't have a use for a cluster system, but they're entertaining.
Make it work, do some brutal testing with it. Really brutal testing.
That Quad board look like such a nice cluster training tool!
The mini UPS sounds like a cool idea. I'm thinking, make it be a shared power supply as well, so integrate a switch mode power supply in there that keeps the batteries charged, and have a bunch of 12v outputs with individual reset-able fuses, plus maybe some 5v outputs. Include a micro-controller in it with some temperature and voltage sensors to keep the charge levels and temperature in check, with an output to a character LCD and a USB port for UPS management.
I did not know about 10" rack systems. Very cool.
@JeffGeerling In reply to your comment on 17:46 about the availability of 10" racks in Europe: I got lucky getting a 30cm deep closed 12U rack from a now defunct Polish company (COVID stock/supply issues I guess) I only could get the MyElectronics 2U enclosure in there by putting in some custom spacers to get the ITX case closer to the glass front door. Otherwise the cables in the back would just not fit. Any deeper rack would not have fitted in my utility closet.
I once revved out the diesel my driving instructor used when I was still learning for my driverslicense, some 300 meters from where MyElectronics is currently based in Alkmaar. I now have one more reason to chuckle about that event, 'some' American guy made realise that they were based there.. :)
PI's are getting insane dude! 😲
I saw a talk a few years ago at kubecon where the speaker was the guy who first named kubectl and he said it was "kube control". And that fits my narrative, so I'm sticking with it
So is Kube pronounced "Cube" or "Koob" or "Coob" or "CooBee" ?
Great question, "cube control" if I remember correctly... It was the "control" bit I was worried about
big QUESTION, how would a minecraft server perform on this?
I’m always highly impressed when someone gets Drupal to do anything sensible at all, let alone a usable deployment of it.
Fever dreaming out loud for engagement: I want to stick one of these cluster boards in a 2x 3.5" bay NAS case for a 3 node apps cluster and the 1 node that has the sata slots being the bulk storage. Alternately, would love to see a laptop form factor that could take one of those RK1s (like the MNT reform, or similar).
MNT reform + RK1 would rock! It's a niche use case and a niche laptop, but if you're in that niche, the RK3588 would probably be the closest thing to a 'good' average x86 laptop experience in Arm-land right now.
I wonder when failsafe systems and ECC memory will be popular🤔
Another question - do you think that the tower cabinet could handle two of the Mini-ITX cases?
[I have two Turing Pi 2 boards from the campaign, along with eight RK1s, ready to go... and have been instigating Mini-ITX cases for a while now...]
Sick video, Jeff as always. Love to see some RGB on that rack. 😊
Thanks Jeff you're such a nice person someone I'd love to meet next time you're in England. David
I ordered new Turing Pi 2.5 with those RK1s with 32GB RAM each. I can't wait! But yeah... elephant is big, and even dual 2,5G would be great. 1Gigs for this is too small bandwith and just because of that I was postponing my ordering since like a year... I finally decided that it might be ok, but I still wish it has faster network.
You read my mind when you talk about a UPS for a mini rack. That would be siiiick
APC's most popular models are like 7 years old and use lead-acid batteries. They don't seem to feel much competitive pressure.
It's such a minor thing, but "sudo su" always bugs me. It feels like when the switch from using su to using sudo went mainstream people said "but how can I use su now?" and found a hacky way of doing it without looking at the documentation.
"sudo -i" gets you an interactive shell using the target user's default shell and runs the login files for that shell. "sudo -s" uses the invoking user's shell. Either feels cleaner imo.
There's many ways to cut a cake, and there's rarely a right and a wrong, but I wanted to put "sudo -i" out there in case others maybe think it sounds neater too.
True; for me I just have muscle memory from whenever ago to use 'sudo su' :D
@@JeffGeerlingI have the same issue: muscle memory! I know about the “proper” way, but “sudo su -“ is so embedded in my brain I can’t seem to switch completely, even though I do some times… 😅🫣
Well, I think "sudo su" is just easier to remember and more in line with all the other "sudo ".
Id rather do "sudo su" knowing that its well tested and works rather than using possibly untested parameters that maybe 100 people in the world knows about.
How about 'sudo sh'̈...
@@hubertnnnIt's well tested, so the limitations are well known. If you want to start an interactive root shell from sudo, it's just not the correct way.
I found with k8s that setting up calico or flannel (can’t remember which one) messed with mDNS on the cluster, it would change the source port of the response and avahi would drop it. It would add some iptable entries and would always put its own rules first even if you manually inserted your own rules before.
No idea if you use those in your script but noticed you’re using mDNS figured it was worth shouting about
I got plenty 10" racks at work and we are using the TP-Link TL-SG1210MPE switch for it (: PoE, SFP, managed.... downside is the external power supply... fits perfectly in a 10" shelf
Not a bad option! I do wish it had all ports + lights on front though, instead of the desktop configuration with the ports on back. Though, depending on what kind of gear you have, it may be cleaner that way!
These RK3588 SoCs are quite amazing to behold anyway, it seems.
From a regular user's perspective, I'd still love to see an ITX board for desktop use but the board you used here is interesting to watch too.
Radxa Rock 5 ITX is perfect for desktop use case.
does the ipmi/bmc do some kind of serial forwarding (SOL) as well or do you just address each board through the built-in switch? also can you bond the ports on the built-in ethernet switch or are they something more like 2 ports on a hub?
Awesome detailed look. The 1Gbps is definitely showing its age. The price is kinda crazy also. Hope they can increase production to make it cheaper
14:00 you could even solder in the power leads on the other side of the pcb
i just suscribed, lets be real, your content is really interesting and i enjoy it :)
If you are going to standardize on 12 VDC devices, you could put a battery in the bottom of the rack. Then you can feed the rest of the rack from there. Could even get a DC power bank and use that to connect to the AC or DC source of your choice and keep the rack powered even in transport.
Thanks. Good info.
Great vid - the sound is very different, and it looks like you green screened your eclipse photo/workspace - is this in your new space ?
I have to say that the 10 Inch Rack just makes sense for small builds where space is very limited. hell I've debated about going that path for somethings after you've mentioned 'myelectronics' a couple of times on top of you deploying their cases for some of the builds
I am eagerly awaiting my Turing RK1 modules. My plan is to build an ARM based CI/CD cluster and I am curious to see if the gigabit connection ends up being a bottleneck.
That's a cool computer mini rack 👍
@JeffGeerling In reply to your comment on 17:46 about the availability of 10" racks in Europe: I got lucky getting a 30cm deep closed 12U rack from a now defunct Polish company (COVID stock/supply issues I guess) I only could get the MyElectronics 2U enclosure in there by putting in some custom spacers to get the ITX case closer to the glass front door.

Ha! Yeah, they could even shave a little more depth from their designs but if you have a deep enough rack or open back, no problem at all.
if you want the led activity indicators from your cluster board, I would try to make a passive light pipe solution with some pieces of clear petg filament, perhaps with a little bit of gaff tape or electrical tape or something to keep the light in the pipes seperate. diy fiber optic.
That’s pretty cool - I want
For price comparison- there are plenty of used epyc cpu + mobo + ecc ram combos on offer for less money.. more grunt, more power bills
If power's cheap, then some used servers or mini PCs are definitely a better option, cost-wise. Power's luckily pretty cheap most places in the US!
@@JeffGeerling then again.. there is no substitute for having an arm cluster in your home lab, when production deployments are likely to be arm based in future as well.
Been using arm AWS instances a little lately, and they do hum along quite nicely
18:30 well you can get some small form factor ups from eaton, well there are just desktop ones and i think you will have to make a bracket of some sort to fix them into place but it schould be doable (maybe they even include mounting kits for 10 inch, its some time since i installed one of them so i can´t remember 100% if it had that or note but from memory the size schould fit)
with the mini UPS thing, could use some of those USB-PD triggerboards and a compatible battery bank. course might want to collab with one of the eletrical engineer youtubers to work out how to make it do passthrough+charge cause some batterybanks turn off when charged up
Have been working with the TuringPi2 and RK1 Boards for a few months and recently also received a few different mPCIe devices, unfortunately with very bad results. Only 1 in 5 boards would show up.
I do hope you look into testing mPCIe devices with the TuringPI2 similar to what you have done with the CM4 as it seems to be either a bit of a jungle compatibility wise or alternatively the faulty connection on the TuringPi2 side.
only board I got working was a IOCREST 4 Port SATA with a 88SE9215 chip, Tried a few realtek ethernet adapters and a different SATA adapter.
PCIe is a weird beast with the RK3588, not to mention through the Turing Pi 2 board. I have had weird issues as well, to the point I don't try many anymore.
Idea for a cluster: take Framework Laptop mainboards (the ones with USB 4 for PCIe tunneling and 10Gbps+ networking) and bolt them into these enclosures. I think you might even be able to fit a full 4 of them in there. the keystone slots at the back up top could be USB-C Keystones for power and for the big opening you could 3d print an IO shield so you could put in other keystones for IO. Fully x86, BLAZING fast IO for that small of a cluster, and possibly pretty energy efficient.
I remember when data rates went from 110 baud to 300 baud. That speed increase was amazing for the time. And years later the first 14,400 baud modem came to market at $14,400 each. These young folks think 1Gbps is slow. They do not know what slow is. It did teach us patience.
The mini rack needs a 10" PDU that has a 110v input power. And as Red Shirt Jeff pointed out, a 10" UPS would be a nice option.
EDIT: A Ubiquiti EdgeSwitch 8 PoE (ES-8-150W) would fit nicely in the 10" rack.
I think that is too niche for it to be ever made, but maybe a 12V UPS would be a good idea for those small racks.
It would be much easier and cheaper to make (since 12V batteries is a standard) and skipping the conversion from 12V (battery) to 220V (AC) back to 12V (PSU) would be nice.
There are 10" C13 PDUs.
Thanks 👍
Thanks Jeff, so x86 is still a cheaper and more practical option as of today? I can buy a stock G9 HPE server with the same number of Cores/Threads and RAM for about 500$.
Maybe a stupid question, but i thought the nvme slot is just a pci-ex port.. when you can write that fast into it, maybe use a M.2 to pcie adapter and a 10gb card ??
(Since it's not a slow wlan port)
BTW I literally saw the person who wrote kubectl at a talk in person and he said that it is pronounced "cube control".
So a bit less cuddly!
@@JeffGeerling to be fair, virtually everyone else seems to call it "cube cuddle" no matter what the creator says.
I've done a fair bit of cluster computing, on big clusters like Stampede at the University of Texas, so I'm familiar with the desire of cluster creators to have fast shared filespace and high speed interconnect fabrics etc - *but* - at least for all the real projects (as opposed to demos or benchmarks) that I've used clusters for in real life, I've always been able to structure my code so that high speed interconnects and fast shared filespace are just are not needed. Even for applications where there was big data rather than just a lot of CPU being used. My observation is that these extreme hardware facilities are mostly used by people who don't make the effort to optimise their application for parallelism and who try to shoehorn code that was really designed with uniprocessing in mind, into a multiprocessing environment without taking on the necessary restructuring. Now I'm retired, when I need to throw CPU at a problem I just farm it out to a few dozen regular Pi's and a couple of spare x86 portables I have around the house, running over Wifi, with one regular NFS mount to supply shared files across the lightweight cluster. In fact - although I do have proper cluster MPI software installed, I generally can get by with just kicking off tasks using "ssh". So I mention all this to suggest that perhaps the features you describe and the cost of the system you're using is perhaps a little overkill, that could be avoided by a little more coding effort. An interesting approach for a subsequent video might be in terms of computation done per dollar rather than just what is the fastest shinyest new hardware available?
Sadly when you talk to anyone about making code better versus beefing up the hardware, 99 times out of 100 you'll be told the hardware's easier :D
One of the reasons I love Pi clusters is I've changed my own site architecture many times to make it faster (avoiding disk IO where I can, caching in RAM on individual nodes, that sort of thing), and made big sites scale (think millions of dynamic page views per hour) on relatively modest AWS resources... all because I would run the same application on my Pi cluster that we were running on $20,000/month servers :D
But not every project allowed me the time to optimize. Sometimes the plan was to build up hardware for a month, then tear it all down, and they were happier doing that spending $100k+, than to spend an extra two weeks optimizing the site (for a lot less).
Read "In Search of Clusters", a fine book. Amdahls Law; show me where the data is and I'll show you where the computing has to take place. At some point all parallel computations reduce to a set of serial instructions. It's the law. Clusters live and die by the speed of their switching fabric, and that will always be the case.
Is there enough pci lanes for the npu,, pci slot usb as well as 10gig for each module? Not sure if they’re using pci switch chips
I just received my rk3588 board today and it's been many years since I did anything with arm, so I'm really excited. It's amazing how fast those things have become. By the way, it does support usb otg 3.1 gen 1, so if you need more bandwidth, maybe that could be a way to do it?
Jeff, have you seen the Mixtile Blade 3 with the cluster box. Looks like a nice clustering box
Lovely labels on the fan box ;) How does this compare to the Ampere 64 core ASRock Rack? Withouth memory that is also $1500, so slightly more expensive.
It's a lot easier to build with the Ampere, it has a LOT more PCIe expansion available, and if you just want a high performance Arm setup, I'd go with the ASRock Rack setup.
I like the cluster so I can use it in my lab for little K3s/Kubernetes testing on real hardware, but it is still not a match for a single high performance workstation/CPU.
@@JeffGeerlingdoes one server motherboard will be faster than Turing pi with 4 boards ? I’d like to use kubernetes for my apps as well, is it worth it to set up a single node cluster on a board you mentioned?
I wouldn't even want a real ups for it, but more just a batter bank to supply 12v to the itx picopsu and maybe a switch, though might need 52v for a poe switch
6:24 is the important moment.
If you want to use two of this boards in a cluster, 10 Gbit/s Ethernet is what you need.
It was mentioned twice in the beginning (a little redundant) and it is what stops me from buying such a board: Ethernet is too slow. The connections between the Compute Modules must be very fast and the connection with the external world should be as well.
Everything else is great. Storage, compute power, all great.
Creative video, thank you :)
Felt like I unlocked a core memory when Jeff slid that Pi Blade out. Forgot I'm still waiting on mine. Soon™
i understand about the LOW_PRO fan in the front but would it be wrong just to unsolder to 2 power and re-solder from the backside aslong as same orientation? @Jeff Geerling
I, (like so many others) are going back to Mint! We've had it with Snap Packages and Ubumtu slowing down. So we'd like to see you using Debian more.
Server on the go? I think this would make an awesome little travel server. Your main mini itx pc, your cluster server, and a travel router would probably fit really well and it looks like it could fit in a little carrying case.
"Worst case, we'll just have a little smoke come out here." and then a little later "all's well that ends in not a fire". Sounds like a good day at the office.
well, now I need that mini rack
I love to see how tech gets smaller and more usefull, and how open source software reigns among certain communities, but boy do I feel 'lesser' nowadays, in the late 2000's I grew up daily driving and tinkering with linux (mainly mandriva at the time), got into programming a bit early still do some, but I'm mainly a digital artist to pay the bills, and I feel so out of the loop, when I hear about tech like kubernetes, having no clue what it is about ahaha
for deep stuff like the RK1 in that rack, it'd be nice if they included rear supports like what the shelf had.
That seems like an easy enough accessory to make-put a few bends in some metal.
@@JeffGeerling Perhaps someone (not suggesting you take this on) could design some brackets that could either be 3D printed, or sent to a service like SendCutSend or OshCut to be laser cut and bent as specified. Yes, additional ones available from them would be nice. They list additional rack shelves for sale, but don't seem to have considered additional support brackets as an item people might want.
For the UPS - it is 12v, so 3s LiPo or 6s SLA would fit the bill nicely - no need to do conversions into and out of AC and DC unnecessarily. For more runtime, just add parallel sets of whichever type you choose (but don't mix them - it is either SLA or LiPo, not both in parallel unless you want a fairly spectacular fireworks display - DAMHIKT). If you go for SLA put them at the bottom of the rack for stability - not a bad plan for either, really.
Making them line interactive or at least work with an AC input is a little harder, though there are some good BMS boards out there these days.
Would it be possible to reverse the side those two power cables come into on the pico-psu? If they entered that mini board from the far side there'd be no chance of them hitting the fan.
Hi Jeff! Have you happened to test local LLM inference on the RK1 by chance? Just wondering if there are any benefits to the RK1 versus any other SBC.
I have not yet; I've seen a few people tinkering with the GPU and with the NPU, but I haven't tested it yet for LLM/inference or camera processing yet.
about 20 years ago the cluster system working on 1G bit ethernet was too slow, which we could get off, our HW teams had a 10G switch backplane and looking at 100G or maybe a 1T switching backplane (but we were working on an edge router for a city 500,000 users per cluster) full HA with fall over in less than 1mS.
but looking at the internet today we may have needed 10T bit
I was initially dismissive of the Turing Pi 2 because of the so-dimm connector and having to deal with external PSUs and so on, but I must say I wasn't aware it had BCM so I might be regretting that a bit now...
So I guess the only good news for me is that the CM5 seems to be closer 😆
Hopefully. And yeah, the SO-DIMM means you have to buy extra adapters for CMs, unfortunately. But it's cool they made a BCM for the board, and it actually works pretty reliably in my testing. Would love to see more standardization in that area too, for others building clusterboards.
you can add 4pin fan header to v 2.4 boards but you have to solder a coonecot and a chip onto the board.
I'm still trying to wrap my head around the use case for such an esoteric machine; what can be accomplished on this that can't be done on a similarly priced SMP server?
It wouldn’t be cheap but if someone wanted to they could use the asmedia pci-e 3 switch chips and break out the pci-e to a 2.5gbe nic and an m.2 slot to make a higher speed connectivity version of a cluster board, going up to 10gbe would add a lot of $$.
Would you ever consider building a system for folding @ home or compute time towards the seti institute and others alike, and power directly from solar energy.?
