The goal is to create relatively low cost NAS' that are still running a full linux distro underneath
Bonus, an easy way to tie it into a cloud offering
Should be fairly hardware agnostic and able to run on cheap low power stuff
https://rockstor.com/ Seems the most promising. Run by an opencollective uses btrfs, for fancy snapshot magic and raid stuff
other contenders:
Custom Linux with cockpit as a web ui
openmediavault
truenas scale
For our “Managed” units probably run rockstor in a hypervisor to allow us to have other workloads
