Quick Video showcasing how the system looks like (Note: This is the original version that I release back in early 2023. See other progress update for latest revision)
The reason I keep updating the design of this project is due to I really want to host a cluster / home lab. However, I don't really like server equipment which single point of failure (SPOF) on a rack mounted switch or power supply. Instead, I decided to go with multiple smaller devices and build my own GFS like cluster environment where there are no SPOF by allowing multiple layers of file abstraction to be run on these low power devices. Another advantage of this design is that I can expand my storage by adding more 3D printed NAS in the future when I needs them, while access speed will also get improved with more nodes added until it is reaching the networking bandwidth of the gateway node's LAN.
In order to make sure I have supplied of these storage device even after 10 years, I decided to 3D printed and use as little dependent materials / parts as possible. Like using a generic SBC, power regulation solution, making my own PCB and 3D printed cases. These ensure I can made and support it in long period of time (aka LTS version of the NAS).
