Abstract :
In this paper, we present the dynamic grid quorum, a technique for reducing the power consumption of large-scale storage systems. The key idea is to skew the workload towards a small number of quorums by means of a novel optimization algorithm. Moreover, this system allows reconfiguration by exchanging nodes without any data migration so as to reallocate high-capacity nodes to busier quorums. We demonstrate that the dynamic grid quorum saves, on average, 6-12% energy when compared with the static configurations.
