My node:
- Orange Pi Pc2
- Armbian OS
- 4TB Western Digital USB3 drive
- Fiber-to-Cabinet broadband, up to 150Mbit/s (about 30Mbit/s upload)
- 1000VA UPS (it’s the black box behind the board)
- LEGO sysadmins (doing nothing most of the time, anyway, this setup is rock-solid!)
The UPS backs up the board (and few other boards) the Internet router, the wifi router and a network switch. My node can “survive” up to 4 hours without grid power.
