Fujitsu D3643-H MB B360 (Intel,1151,DDR4,Micro-ATX), S26361-F5010-V160

Product Information

A; It's not too expensive, I already had the motherboard and it doesn't suffer much from the Intel SMT bugs. ZIL and SLOG: https://www.truenas.com/community/threads/some-insights-into-slog-zil-with-zfs-on-freenas.13633/

cannot spend too much right now but I can delay some expenses to some months from now (placing 8 or 16 GB of RAM now and buying other next fall for example) WD Red Pros or Seagate Ironwolf Pros are good drives, but afaik write power consumption is about 5-6W* PER DRIVE. So with 16 drives that's already 80watt... It's a topic not discussed much, but disks are actually quite a heavy power sink even at low load... CPU: Intel Xeon E-2288G (Coffee Lake-R) 3.7 GHz (w/iGPU transcoding after TrueNAS 12.0-RELEASE upgrade) Update 2018-08-24: with the Fujitsu D3643-H there is now a board available that offers two version 1.2 DisplayPorts (up to 4K resolution at 60 Hz). As with most Fujitsu mainboards, the D3643-H is optimized for low power consumption and high reliability. Wi-Fi and Bluetooth

Which leaves me at about 150W for the system itself, which isn't stressed (much) during disk spinup. The other option would be a Fujitsu d3446-s21 gs1 (it comes with an intel i5 6400). Price difference with previous is about 10 euro. Would this be the better choice of the two? This seems the more "professional" board to me, but my knowledge is limited on this part and I can't find that much information on home servers with this board. Would this give me a good base to start on? Terminology and Abbreviations Primer: https://www.truenas.com/community/threads/terminology-and-abbreviations-primer.28174/ One caveat to be aware of: in sleep mode, the system consumes 12.6 Watts, which is about 12 Watts more than it should. This is the case even with the ErP Ready BIOS setting enabled, which is supposed to make the system conform to the EU’s environmental regulations. I worked around this inefficiency by configuring Windows to hibernate when the power button is pressed instead of sleeping. During hibernation, the system only consumes 0.2 Watts. Noise Emissions / Silence Intel i219LM embedded NIC on B360 chipset will likely require an extra.lzma with newer Intel drivers.

Spindown is per drive setting... But keep in mind that all drives are mostly writen at once* and the times for spindown (regardless of how low its set) only starts counting down when a drive is on standby. Power supplies: https://www.truenas.com/community/resources/proper-power-supply-sizing-guidance.39/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. 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.

To return faulty items see our Returning Faulty Items policy. 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). 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 […]

The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants. 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. IPMI support, if Supermicro is better because I would need to manage only one kind of IPMI interface since I already have one That will kill your PSU. Supermicro's *SMALL* spec for a 24-bay chassis is the 920 watt dual module supply, which is not sufficient to guarantee brownout-free spinup when one of the PSU modules is removed.

I expect someday to run draid, but thats way off still... I'm also looking into the power efficiency of certain options. I might even go 2.5" drives.
