Mark, could you provide some numbers for cluster size, number of objects and the rate of change for both Ceph and Swift? I imagine some of it may be proprietary, but perhaps the rate of ingestion is available? E.g. Swift is NN% today, Ceph is MM%, rate of growth is XX%? Last time we have Summit presentation on the topic, it was by San Diego Supercomputing Center. Last time I saw anyone publish their Swift data at all, it was Turkcell who had a 36PB cluster and planned to grow it to 50PB by end of 2019. They started that cluster in Icehouse release with 250GB drives! Thanks, -- Pete
