A New Placement-Ideal Layout for Multi-way Replication Storage System
Technology trends are making sophisticated replication based storage architectures become a standard commercial practice in today's computing. Existing solutions successfully developed optimal and near-optimal parallelism layouts such as declustered parity organizations at small-scale storage architectures. There are very few studies on multi-way replication based storage architectures that are significantly different from parity based storage architectures. It is difficult to scale up to a large size because current placement-ideal solutions have a limited number of configurations. In this paper, the authors retrofit the desirable properties of optimal parallelism definitions in parity architectures for replication architectures, and propose a novel placement-ideal data layout shifted declustering.
