Not sure if any of that is helpful for your case but I recommend trying something if you’ve got spare hardware, and see how it goes on dummy data, then blow it away try something else.

This is good advice, thanks! Pretty much what I’m doing right now. Already tried it with IPFS, and found that it didn’t meet my needs. Currently setting up a tahoe-lafs grid to see how it works. Will try out ceph after this.
