That system also sounds a lot more capable than mine. How did you end up with 25 VMs?

I’m running it in a regular mATX case (Node 804) but I think you can also get AM5 motherboards in rack-mount cases.

Perhaps my recent NAS/home server build can serve as a bit of an inspiration for you:
- AMD Ryzen 8500G (8 cores, much more powerful than your two CPUs, with iGPU)
- Standard B650 mainboard, 32 GB RAM
- 2 x used 10 TB HDDs in a ZFS pool (mainboard has 4x SATA ports)
- Debian Bookworm with Docker containers for applications (containers should be more efficient than VMs).
- Average power consumption of 19W. Usually cooled passively.
I don’t think it’s more efficient to separate processing and storage so I’d only go for that if you want to play around with a cluster. I would also avoid SD cards as a root FS, as they tend to die early and catastrophically.
- Comment on Mini PC for Jellyfin 2 months ago:
No, they’re almost entirely unrelated. Almost all CPUs will idle close to 0 W (with correctly working drivers). The main idle power contribution comes from the mainboard and other devices (e.g. disks). The Mini PCs you mentioned should have a very low total idle power, probably below 10W.
Check out Wolfgang on YouTube, he has some great videos on the topic: youtu.be/Ppo6C_JhDHM
- Comment on Switching from a Media Drive to my first self-build NAS 2 months ago:
I’ve also recently built my own NAS and I’ve gone through similar considerations. One of my mayor decisions was not to use btrfs because it’s not recommended for Raid Z1/Raid 5. With that, I landed on ZFS and TrueNAS Scale. Note that RAID expansion should be landing in both very soon.
Things with TrueNAS were pretty easy, very quick, and everything worked nicely. However, I noticed that it was constantly accessing the disks and preventing them from spinning down. I really wanted to keep the power consumption low (<20 W idle), so I eventually decided to just go with Vanilla Debian + ZFS. I can recommend that if you want to tinker with things yourself. Otherwise, I’d recommend TrueNAS Scale.
As for migration, you might be able to create a degraded pool initially, copy over the data, and add the parity disk last. Raid expansion would ofc also help there…

Sure, but those are completely different approaches. Dams have the advantage that they have a much larger capture area for water and that they can accelerate the water beyond the 10 m/s terminal velocity of raindrops.

Raindrop energy harvesting is a rubbish idea. The raindrops simply don’t have a meaningful amount of energy to begin with: news.ycombinator.com/item?id=36907674

The article says they are aiming for 1W in the next couple of years, which can probably do it.
They won’t magically improve the power density by three orders of magnitude. They’re just trying to defraud their investors.

Do you have a source for that? According to WikiChip Fuse, Intel 4 is comparable to TSMC N3 in density and offers better performance: fuse.wikichip.org/news/6720/…/4/
On paper, those PPA characteristics positions the company’s new Intel 4 process at performance levels better than TSMC N3 and Samsung 3GAE. On the density front, Intel 4 appears highly competitive against N3 high-performance libraries.
