So, I promised in the other Nanopi M4 thread to open a separate thread for my little project. Before this I had a Zyxel NAS542 with Debian and OMV on the SD card. It dies in December and I got a replacement from Zyxel and sold it. It wasn't a very good solution. It was just to slow with OMV. I was looking for a DIY solution and then FriendlyElec came out with their SATA hat and I decided to go that route.
- Nanopi M4
- SATA HAT
- Meanwell LRS-100-12
- HDD Cage
- 4 Pin Molex Power Cable (maybe you have one laying around)
- Power Switch
- Power Plug
- SATA Power splitter
- SATA cables
- 120 mm fan (PWM)
- fan dust cover
- crimping accessories
3D printed parts (I haven't added them yet):
- I had two Seagate IronWolf drives from my previous NAS (still RAID 1, will convert to BTRFS)
- SATA SSD for OS
- Sandisk A1 sd card (basically only there to make it boot from the SSD)
It looks a bit messy right now. Once the SSD is propperly mounted it might look a bit cleaner. I have the two HDDs mounted on the little sleds. The power supply is mounted on the top vie standoffs and the NanoPi ist mounted inside via standoffs. I drilled holes through the HDD cage for all of the standoffs. To connect more than two drives to the SATA hat you'll need a SATA power splitter, because the hat only comes with a molex to 2x SATA power adapter. I cut the end off of the molex to 4 pin power cable and crimped the appropriate ends for the power supply (if I remember correctly there are M3.5 screws, I think I used crimp terminals with a M4 holes) and connected the power supply to the SATA hat. The hat then powers everything. The power supply is then wired to the switch and the plug. I might need to solder a separate power switch to the SATA hat, because the power button is not accessible right now.
Thw fan is mounted in the front and has a little magnetic dust cover. It is not connected yet, I need some cables for it.
Finally I installed Armbian, moved the OS to the SSD and installed OMV via armbian-config. My old RAID was recognized
I am thinking about some sort of case around it. Or at least something to cover the back a bit and install the power switch and plug.
