Upvoted, but I skimmed 5.1 and missed the "shown not to work" part. Can you be more specific?

- wmf 15y agoWhenever a device fails or goes offline, the data that was stored there needs to be re-replicated from the source. But figure 6 shows that even with a 2 Mbps "turbo" uplink you can only replicate ~25 GB; if you have more data than that, replicas will fail faster than you can recreate them.
- jbellis 15y agoSounds like that's addressed by storing pieces of data from many sources in the non-local part of space monkey storage: even if each source only has a 256K uplink, multiply that by 100 or 1000 and you're in pretty good shape.
