Nextcloud would be much cheaper to run on a x86 board.
Can you expand on why?

Re: Raspberry Pi Server Mark III
#92Very cool. Do I understand correctly that there's no traditional backplane on this, power and data are both provide via ethernet?
The Pi does not do poe natively. POE is available as a hat, but I have not seen one for the Pi4 yet. The hats are nearly as expensive as the Pi itself.
The PoE Hats are $15-30 on Amazon. That makes the most expensive one 30% of the price of a Pi4 8gb.

#93The Raspberry Pi Compute Module 4 with support for PCI Express will be ideal for something like this.
Re: Raspberry Pi Server Mark III
#94Running a 6 node cluster of Pi4s at home now. Did some benchmarks. Long story short. USB thumb drive boot disks are better performance and cheaper than SD cards. Fans are completely unnecessary on a Pi4 with an aluminum heat shield style "case". They do run hotter than with a fan, but they will not be heat throttled with recent firmware.
I used the following case/setup and can confirm. No fans are required and booting is lightning fast. https://www.prusaprinters.org/prints/40852-pi4-case-stand

Some usb drives are much slower than a decent sd card. Also, the ultra has cooling issues.
However, there are usb3 nvme enclosures that are incredibly cheap, and blow both out of the water:

For a build like the one in the article, I imagine something that puts two nvme sticks beside each other, sandwiched between every other rpi, with passive aluminum heat shields in the remainder of the spaces between the rpi’s. I bet it could be even denser (more pis and more storage) and quieter.
I wonder if space can be saved by making a heat shield heatsink that has a pi on both sides, and fins in the middle.
Super cool article.

All fourteen Pis, even v4s (which are significantly hungrier), would be lower power (as in electrical draw) than even a feeble (as in compute power) traditional machine. If you can distribute your workload (or it's not intensive anyway), i.e. having no single machine with a faster processor, then I think it's a good choice, cheaper to run. Edit: I'm happy to be corrected if down-voters would like to reply... A Pi 4 d…
Did not downvote but desktops idle way below 100w.
Idle as in powered on, not sleeping, just 'no' workload? I stand corrected if so, I didn't realise that was the case.
I also like the idea of having an easy homogeneous setup, each Pi having one disk, vs. my alternative (old PC parts) being something like '4 SATA ports on this one, and 6 on that one, but one's broken, less one on each for the boot disk' - I quite like the idea of having a bunch of Pis, and one image that I apply to all of them, which can include details like /dev/sda being its only data disk. That's not really a functional advantage, just appealing for keeping it simple to come back to and remember/understand how I set it up when I need to tweak something (and really easy to add another one increasing available cpu/ram/disk).

Yeah, I recently spied the 4 node Jetson Mate carrier board on CNX that facilitates building your own Multi GPU cluster ;) https://www.seeedstudio.com/Jetson-Mate-Cooling-Kit-p-4784.h... They recommend Kubernetes for private cloud workloads. But I am wondering if there isn't room in the ecosystem for a new virtualization / containerization technology to orchestrate tasks on multi gpus? Have heard NVidia is developing…
yeah, I'm excited to get my hands on some Jetsons too. the 4gb memory on the pi is really a big pro though. when one of these SBCs finally comes with 8GB and GPU acceleration for < 100$ we will see some real progress I think.
> when one of these SBCs finally comes with 8GB and GPU acceleration for It might have GPU acceleration but the RPi already comes with 8GB of RAM for about 80$.

Re: Raspberry Pi Server Mark III
#99What could you do with a similar setup? I mean: what's the purpose and/or the advantages compared to a "classical" solution ?
You can neatly mount your Pis in your rack where you have the rest of your gear supported by network switches, power delivery, cabling, cooling, good internet connectivity connectivity (if housed in a machine room or colo) etc.
Re: Raspberry Pi Server Mark III
#100This is so exciting. Is this type of "movement" (trend) likely to see data centers coming back on premises for enteprise markets? (ie. back from cloud)
Depending what you are doing. For use cases like Dropbox cloud was never an option, other use cases can realize 30% year over year saving just by moving to the cloud. I think where RPIs make the most sense is soho, office building use cases, onsite backups, NAS, hosting infra services (DNS server for example) where you can use many nodes without much power and with a good amount of redundancy.
