Arrogant NAS

Quickly the fairy tale affected, but for a long time the thing was done.

More than a year and a half ago, I wanted to build my own NAS, and the beginning, to collect the NAS, was to restore order in the server room. When disassembling cables, cases, as well as moving the 24-inch tube monitor from HP to a landfill and other things, a cooler from Noctua was found. From which, by incredible effort, removed two fans - 120 and 140 mm. The 120 mm fan almost immediately left for the home server, as it was quiet and powerful. But what to do with the 140 mm fan, there were no thoughts yet. Therefore, he went straight to the shelf - in reserve.

Somewhere, two weeks after putting things in order, we bought a DS414j model from Synology NAS. Then I still thought, why two fans, if you can have one big one. So, actually, from this the idea was born - to make NAS with one big and quiet fan.

So it was a saying, and now a fairy tale.

Since I had experience working with a file, I had previously built a six-disk drive basket into my home server, I approximately presented the outlines of the future NASA. Full face is a large and quiet fan with a grill, the profile is a regular rectangle, slightly larger in size than a two-disk basket. And everything else, maxim harmonious and not bulging.

And work began to boil ... for a year.

Designing and designing again, before starting work, I am convinced of this, for the umpteenth time. But, since this is a hobby, and the deadline is almost impossible, he did and improvised, and again did, and again improvised, and so on to a working state.

So, where to start and what materials to use?

It was decided to use aluminum corners and aluminum plates, since they are moderately strong, lightweight, and most importantly, aluminum products are malleable for experiments. Further, I purchased a corner of aluminum 20x20x1 mm, 2 m and a corrugated sheet AMg2 1.5x600x1200 mm. From the sheet, in the future, I also planned to make the case walls for the virtual machine server. So, the beginning in the photo.

Appearance, of course, is not so hot. But most importantly, the functionality, which then was enough in abundance.

In size, the future NASa, focused on the size of a 140 mm fan, two baskets for 3.5 disks and a power supply. The size of the board of the “smart part” of NASa did not play much, since, in comparison with other components, it was quite small. And, I thought, somewhere, it’s still possible to screw it.

What happened later, the board of the “smart part” of NASa took its place.

In the meantime, the work on placing NASa elements was underway, the future case for the virtual machine server was born in my head, but more on that in the next article.

By cutting, drilling and joining together, it was finally possible to assemble a suitable box.

I thought that for the first practical work on the manufacture of NASa, it is quite normal. And he began, to settle all the components in places, put the drive cages downstairs, the power supply upstairs. Although, at present, the NAS is different, the power supply is at the bottom.

And as I said earlier, the production of NASa took a long time, primarily because of the long delivery and selection of characteristics and prices: disk baskets, power supply, USB-to-SATA converters, NASa's smart part board. Then I needed “G” shaped cables, which I also ordered in the same large, well, very large, electronics store. Since 5V and 12V are perfectly enough for powering SATA disks, the power supply unit chose a two-channel one: 5V and 12V, with a power of 75 watts. I used the wires for the power supply from the “5V” and “12V” terminals from the old standard computer power supply, and for the 220V supply I cut off the female connector C13 and connected it to the “AC” terminals with wires.

And here is the result, all components are assembled in the case.

If you look at the device from the side of the drive baskets, then for the "smart part" of NASa there was a suitable place, to the left of the power supply and above the drive baskets.

So what was used for the "smart part" of NASa? Particularly big-eyed, could see in the photo, and yes, this is OrangePiOnePlus.

This board, first of all, I liked the ratio of price and filling. Since, in the future, NAS did not plan to use it for any other purpose, except as a file storage, then I chose the board for this particular device. Two USB ports for two disks, a network 1G port, an SD card slot and 1GB of RAM - all you need and nothing more.

On the 2 GB SD card, I uploaded the server Ubuntu 16.04 image, the system booted up and started testing. Testing consisted of copying over the network to the NAS, from it and between disks.

Copy to NAS.

Copy from NAS.

Copy between drives on a NAS.

And here is the finished version of NASA, which went to the far and dark corner of the cabinet.

To summarize, I’ll say the following, for more than half a year now, the NAS acts as a backup storage and pleases with its work - it is quiet, modest in nutrition, and reliable. About reliability, I note that in the first month of NASa, one drive stopped seeing. But the system worked and the data was saved every night. At first he sinned on a hard drive, but when replaced by another, obviously working, a miracle did not happen, the disk continued to not be seen. The next replacement item was a USB-to-SATA converter, and yes, a miracle happened, the disk saw both the old one and the one that was intended to be replaced.

This tale is over.
