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 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.

A: At first I will use a placeholder setup (raidz2 or something), goal is to run DRAID with 3 groups of 7 disks with double parity and 1 hot-spare and a tripple mirror metadatavdev 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. 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. 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 First of all, update the BIOS to the latest version, then load the defaults. With that in place, configure the following settings:Which leaves me at about 150W for the system itself, which isn't stressed (much) during disk spinup. Helge Klein (ex CTP, MVP and vExpert) worked as a consultant and developer before founding vast limits, the uberAgent company. Helge applied his extensive knowledge in IT infrastructure projects and architected the user profile management product whose successor is now available as Citrix Profile Management. Helge is the author of the popular tools Delprof2 and SetACL. He has presented at Citrix Synergy, BriForum, E2EVC, Splunk .conf and many other events. Helge is very active in the IT community and has co-founded Virtualization Community NRW (VCNRW). Once I knew I wanted the i7-8700K I went to look for ways to run it at next to zero decibels. This is where c’t magazine comes in, probably the world’s only truly fantastic computer magazine left. c’t regularly publishes PC builds that focus on low noise emissions and energy efficiency. One of the best aspects of their builds is that they ignore unnecessarily complex techniques like water cooling or insulation, opting for noise reduction at the source instead. They basically put the fans in the right place of the chassis and test the hell out of the components to make sure none of them emit any unwanted noise.

So I've been looking into second hand. The nice supermicroboards can't be found second hand for a reasonable price at the moment. And as I've come to understand over here, the consumer boards I'd better not use as well. This kinda answers the question already, but I'm gonna ask it anyway. With the very limited budget I can get (both secondhand): Maybe or not, surveillance does mean your disks are constantly getting data writen, which changes the chances of spin down to about 0. Which means your "idle" would include spinning disks, which is significant. Now, really, I've heard all the stuff about how I'm wrong or how I'm an idiot or how I don't know what I'm talking about, and I can serenely listen to that all day long. If you look at 24-or-more drive arrays, the *lowest* thing I have seen is an 850W nonredundant PSU on the Storinator Q30, which is only possible because they stagger spinup (this is also not their default option, which is a dual 1400W PSU). Your typical Supermicro 846 is a pair of 920W PSU's (1840W available to spin) or 1280W PSU's, HP is IIRC redundant 1460W, etc. I have a hard time thinking all these other electrical engineers are crazy too. Here is your board specs: https://www.kontron.com/products/boards-and-standard-form-factors/motherboards/uatx/d3643-h-uatx.html

Multi-thread performance, while probably overrated, is not unimportant. There are quite a few applications out there that do use multiple threads at least part of the time to speed things up. 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. 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).

PSU failures are not a "limit" type thing. If you hit a point where the PSU actually fails, you are already so far over the line that irreparable damage had probably been done at a substantially lower load. HP, for example, built their MicroServer Gen 8 with a 200W PSU for a 4-bay AMD Athlon based system. The supply is incredibly underpowered and there's actually a company that has made a good business out of 350W PSU upgrades for it when the undersized supply eventually fails. That's for a four-drive system.

Vendors in the gaming space often make wonderful keyboards, but their software is not always up to par. Take the Razer Huntsman Elite: its software is a whopping 422 MB […] AFAIK the Node 304 only has 6 bays. I used a Node 804 for mine, which has 8 (and all are filled), so if you want a fair amount of room, you might consider that. 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.
