It in fact has a low-power chip that seems intended for 'embedded', and a nice case. I think the actual usage of the computer is around 6-12W. Four of these show up: cpu0 at mainbus0 apid 0 cpu0: AMD GX-412TC SOC , id 0x730f01 cpu0: package 0, core 0, smt 0 I don't mean to say you shouldn't use aarch64. Just that I found this to be low power and very reliable, and because it's amd64, to have almost no "this program doesn't work on CPU X" issues. And, I didn't find something with multiple interfaces and 4GB of RAM that came in a box with good mechanical/thermal design, a few years ago. signature.asc Description: PGP signature

I guess if you wait long enough the mainstream stuff becomes sort of embedded stuff. This would be easy to build and run NetBSD as well... Andy

I use this with NetBSD: https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/open-source-hardware It has even a SATA port (but you can only power a 2.5" disk since it provides only 5V power; if you want a 3.5" you need probably an enclosure with power supply). The board takes 5V and consums up to 0.650A; if you add USB devices (2.0), you can add, at worst, 0.5A per device. I use it for a GIS server, with low trafic, and since it is mainly vectorial stuff, only an USB key as storage with some tens of GB is needed. I have just made these days the computation of the energy needed (with the configuration, the programming and its use for now: mainly it processes files on a daily basis to update maps and databases, producing even xlsx files, but via a cron job called once at end of working day) and it consumes only 30kWh / year... -- Thierry Laronde http://www.kergis.com/ http://kertex.kergis.com/ http://www.sbfa.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
Re: Low power server ideas
I don’t usually post here but felt this might be relevant. I use thin clients for most of my servers now. Currently using OpenBSD on them but NetBSD should work just fine. I have a mix of HP and Wyse units including the HP T5740 (5470? Sorry. Tired.) and the Wyse Dx0D and others. Only advice I’d give is swap out the SSD module for an actual drive using something like these: Cable Matters 2-Pack 22-Pin Power and Data SATA Extension Cable - 20 Inches https://a.co/d/6GwYe0Q I also have a SATA to mini pci adapter and run a mini pci SSD in one of them. I don’t think a SATA->M2 adapter would work due to physical space requirements though. I run all my DNS, firewall, etc. on those units as well as a Foundry VTT server. So far they’re good units and don’t eat a lot of power. -- Mike "Right then!

Looking for other ideas if anyone has any. Thanks. Andy if it may still be an amd64 architecture, the "cheap" Intel NUCs are worthwhile in my opinion. The power consumption of my NUC7CJYHN including 8 GB RAM + 2 TB SSD is about 4 W in idle and about 9 W under full load. As a barebone, you can currently get the device for about 130 EUR. I'm currently rebuilding my small business server on this platform, and I'm pretty excited about how well NetBSD 9.3 with Qemu/nvmm runs on it. I'm running it as a virtual host for four VMs with ZFS ZVOLs as backing storage. Apart from a few minor problems that are solvable or under control, the system runs very reliably so far. Kind regards Matthias

Solid and very low power. Quartz64 Model A would be my alternative suggestion, but there is currently no support for the SATA port (and only one of them is usable if you use the PCIe for NVME).

I am not sure this is low enough power, but the PC engines apu2 has 3 GbE interfaces and has pretty low power consumption. My UPS reports 37 VA, and that's an apu2, a USB hub, 2 ethernet switches one of which isn't particularly low power, and a POE access point on one of the switches. It's an amd64 cpu and can be had with 4G RAM. Serial console only, no video at all. Mine runs until I upgrade the software or the power is out longer than the UPS can deal with. It is not particularly speedy CPU wise, but it's been great as a router/firewall/dns/everything-like-that running NetBSD. signature.asc Description: PGP signature

Low power server ideas
Hello all, I've been running a NetBSD server on i386 for about 20 odd years, I should go back and check when I actually started it. I sort of accidentally upgraded it to amd64 a while back but it worked. Anyways, it seems like time to move to something else, maybe lower power if possible. I found this which is very interesting: https://blog.netbsd.org/tnf/entry/making_rockpro64_a_netbsd_server Using a 128gig internal MMC would be plenty for OS and some local storage then I would add some other disks, possibly SSD. Looking for other ideas if anyone has any. Thanks. Andy
