Description

So basically, this desktop is basically being used as a server. It is running FreeBSD, and the monitor is pretty useless because I'm not actually going to be using it. The plan is to add all twelve 4TB drives to a RAIDZ2 pool and offer effectively 40TB (about 36.8TB usable after formatting and what not, with a 2 drive failure tolerance. It also has a UPS (Power Supply), which I had bought for my previous build, and I have a script that automatically quits all programs and shuts down when the power supply loses power. At the moment, ignore the ratings on the hard drives, I haven't had a chance to test them yet.

Build Log:

Part 1: Initial parts were easy to put together, consisting of the case, motherboard, ram, cpu, SSD, and power supply.

Part 2: Scythe fans are absolutely amazing, but they're SOOO LOUD! Of course, I forgot to get a controller for the fan!

Part 3: Got a controller, got the rubber gaskets, at full speed, they don't make much noise now. NOTE: add the fans and make sure everything is ready BEFORE you insert the hard drives. The fans are hard to take out if you have the hard drives in the way. Controller works great.

Part 4: First try of Silverstone mount: fail! Will retry tomorrow. Hopefully it will work out, I don't want to have to return the Silverstone mount.

Part 5: I had to take out my motherboard, but I finally managed to get in the Silverstone mount. I also had to unscrew the super small screws on the side which interfaces with the fan, but luckily, I had a friend with me that was capable of screwing them back in in the weirds ways on earth. In any case, I'm pleased to report that this case has more than enough space for this Silverstone mount and works BEAUTIFULLY with it. I haven't yet gotten the PCIe SATA cards yet, I haven't yet connected 7 of the drives yet, and I also haven't yet gotten the expansion mount for the SSD.

Part 6: I got the rest of the parts and the expansion mount for the SSD. The expansion mount is definitely well thought-out and the SSD fit smoothly into it. I needed one more part: the motherboard requires me to have the molex adapter plugged in, so it is likely to use about 40W on full load now. And I don't have enough molex connectors, so that's another thing I had to order.

Part 7: Well, got the extra molex splitter plugged in and all working. It turns out that my hard drives are getting too hot though. Perhaps I need to increase my fan speed. This case is also probably not ideal for this, especially without that bottom fan. I'll update again if I run into some issues that would make me have to change my plans.

Update: so if I leave my Scythe fans at full speed, it works fine, keeping most of the drives under 35C. Only 3 drives get hotter than this, and on average, they're 48C, 42C, and 39C. Another thing is that the Silverstone mount is not idea for this case. I will definitely be checking product compatibility more next time. At the moment, I just screwed both of the fan interface together, and just left it like that, because otherwise, the interfaces do not align and the included fan will not work. A more intelligent approach would be to get a fan connector female to female so that you can extend the fan headers, but I'm too lazy to do that right now, and I'll probably do it sometime in the future if I ever become bothered by it. Everything else is fine and working. SSD is the boot drive, running FreeBSD 10.1, the drives are in a zpool raidz2, and effectively offers about 3.3TB (but I left some extra padding on the drives, so it is actually 3.2TB), as calculated by FreeBSD (it reports with respect to 230 instead of 109).

It really depends on who you are and what you do

I am approaching nearly 10 TB of media right now, and I basically needed some way of making sure that I won't spontaneously lose half my data, so I built this rig to have some amount of error correction through RAID6 (Z2), and failure tolerance. I work with media on a regular basis, and have a number of 4GB+ files (1.5billion and higher resolution images).

holy smokes.. nice

your mobo only has 6 SATA 6 Gb/s ports, so how are you running 1 ssd and 12 hdd? Not to mention that case only holds 8 drives, and your psu is borderline, not sure if it can even handle all what you have listed.

Plugable USB 3.0 SATA III Docking Station

no no, I'm only getting that so that I can move data from my previous files.

@comptech0408 three of these: IO Crest 2 Port SATA III PCI-Express x1 Card (2 * 3 extra = 6 extra SATA) one of these: SEDNA - PCI Express (PCIe) SATA III (6G) SSD Adapter (1 extra SATA, will not use, but also mounts the SSD) Overall, 13 SATA 6Gb/s ports. Power is over estimated by PCPartPicker, the Mobo uses about 17W, not 70W, and if it ever becomes a problem, I can undervolt my CPU, or even swap the 1200W from my previous desktop that is only using about 300W right now if it all end up being too much of a problem.

The case only holds 8, that is true, but I also have one of these: SilverStone CFP52B 5.25-Inch to 3.5-Inch Bay Converter, that converts 3 5.25'' bays to 4 3.5'' bays. Effectively gives me 12 3.5'' bays. And the SEDNA mounts the SSD.

sorry about the formatting, I haven't yet gotten used to reddit. Formatting not intuitive.

I don't use Reddit either :P I'm just used to HTML formatting so I did that a few times by accident :P

48 TB of storage. WUT

That's not quite the case. 8 of those TB are for redundancy drives, so more like 40TB, which is recognized as 34TB by arch (and then I have a 2TB buffer, 100GB on each disk, so that I can easily replace a disk with another one even if it has hundreds of sectors less).
