Abstract: We present a power-saving technique for datacenter-scale distributed storage systems. In particular, we focus on storage in environments where a large number of data are continuously uploaded, as typified by the platforms of social networking services. In achieving this objective, the main idea is to use virtual nodes and migrate them dynamically so as to skew the workload toward a small number of disks without overloading them. We improve this previously introduced idea by making the data migration strategy flexible in the present study. As a result, our proposed technique can maintain a high-load aggregation rate during the continuous addition of disks, which was difficult to handle in our previous study. The performance of our technique is evaluated in simulations. The results show that our technique improves the technique in the previous study and effectively skews the workload during a constant massive influx of data.
