Sounds like you're looking for a global cluster. You don't need multiple rings for this. Swift can support this. When you add a new device to a ring, you add it in a different region, and Swift takes care of it for you.

Here's some more information:

Now, I would like to add two more Object Store nodes, but as a separate "datacenter" as it were and replicate between my existing ring and the new one. Now, Im not sure exactly what to do for the account/container/object rings and how to get them to replicate (so if one goes down the other will still continue to serve data). I am also going to try and add another storage node just as a backup for existing data. Would anyone have any good links to send me I would appreciate it!
