created by Fujitsu: a data-sheet is imported from an official source from a manufacturer. But the data-sheet is not yet standardized by an Icecat editor. I blame Intel’s Z370 chipset, the only chipset currently available for Intel’s 8th generation (Coffee Lake) CPUs. According to other people’s measurements, the GPU consumes a bit less than 10 Watts when idle. Interestingly, it does not matter whether you connect one or two (4K) displays to the GPU. There is not even a significant change in power consumption if you connect a single display to the mainboard’s Intel graphics instead. Motherboard manufacturer with highest power efficiency (and preferably server grade): Fujitsu, now rebranded Kontron Being active within the ZSTD community I already know what was comming, so have been preparing for quite some months by now: A; It's not too expensive, I already had the motherboard and it doesn't suffer much from the Intel SMT bugs.

reading various official hardware sizing guides and user builds I find it hard to decide how much CPU horsepower I'll need for my use-case. First thing I was thinking about was the chassis. Considering I don't live in the USA right now I need to buy something that can be shipped to Europe someway. I found some good candidates, even from old posts on other forums like this on LTT, and at the end I think I will go with the Node 304. All the hype around Apple must have something to do with the quality of their products, it cannot be clever marketing and cool design alone. Example: Power Consumption This weekend […] There have been great improvements in idle power consumption in the past years. As an example, c’t published a build for an 11 Watt PC in December 2016. This i7-8700K build, unfortunately, is not as efficient. The best I observed is a little more than 36 Watts. The typical idle power consumption is around 40 Watts. If you need Wi-Fi and Bluetooth, I can recommend the Asus PCIe network adapter AC2100 (PCE-AC58BT). It works out of the box without the need to install anything from the CD (!) I found in the box. Just connect the external antenna (excellent signal strength!) and the internal USB cable (required for Bluetooth).

The need for Space I have currently won't ever exceed 10TB so I thought about getting 2 4-drive RAIDZ1 vdevs resulting in a total capacity of 24TiB (with 20% free space in mind). Maybe I'll just do 1 vdev resulting in 12TiB. I can still expand later on.

A: I want to max ram before adding L2ARC and don't really have much need for SLOG at the moment. It's a long-term todo. That is unfortunately not correct. Only when “Enhanced Turbo” is enabled does the CPU reach 4.7 GHz. If it is set to “Auto”, the CPU never reaches more than 4.5 GHz. With “Auto”, most of the time the maximum is at 4.3 or 4.4 GHz. I am quoting frequency values as shown in Windows Task Manager and Intel Power Gadget. I do not have the equipment to measure noise emissions, but I can say that the machine is nearly completely silent. Only when there is no ambient noise at all can a very unobtrusive mid-frequency ventilator humming be heard. This does not even change during prolonged periods of high load. CPU Performance ZIL and SLOG: https://www.truenas.com/community/threads/some-insights-into-slog-zil-with-zfs-on-freenas.13633/ Meet Dozers big brother: Acco. Named after the Acco Super Bulldozer https://en.wikipedia.org/wiki/Acco_super_bulldozerHome Surveillance, okey your disks are not going to spin down much, period... so your idle is basically "Idle with disks". In that case I would advice 2.5"drives, because you are hard pressed in doing 80W idle with 3.5" disk spinning don't preclude the chance to go with 10Gb/s in the future (one SFP+ port would be very good or at least a PCI Express solution as in the other system) I just told you my setup, which I refered to as an example of the powerlevel you where looking for. With the above in mind, we can define our ideal CPU: the highest possible single-thread performance with good multi-thread performance. As it turns out, that CPU is currently Intel’s i7-8700K. No other x86 CPU matches its single-core speed, and with six cores total it is a more than decent multi-core contender, too. Component Selection

Don't use RAID: https://www.truenas.com/community/r...bas-and-why-cant-i-use-a-raid-controller.139/ I would like to reconsider one of the cases I evaluated. I found that the case used by Supermicro for its solutions is actually just an Ablecom rebranded. It seems to be really cheap and surprisingly I can find it in Europe without problems. Do you have any more low-energy mainboard recommendations? Information on the web seems really scarce on this. I live off the grid (completely solar-powered) and want to replace the Macbook with a powerful workstation with, of course, as small an energy footprint as possible. Partitioning the boot drive: https://www.truenas.com/community/resources/i-have-to-waste-an-entire-drive-just-for-booting.187/ In short (and yes this is not 100% accurate*, but lets call it 95%) FreeNAS writes to all VDEVS in a pool at once and with raidz it writes to all disks in a vdev at once. So either all disks are idle (and thus might(!) spin down) or all stay active and keep running.So simply put: If you keep writing constantly, the disks never idle and thus never reach a chance to spin down. Regardless of how spindown itself is handled... (For spindown, a disk needs to be idle. If no disk ever idles, it wouldn't spin down regardless of the spindown setting).
