Storage and Repair Bandwidth Tradeoff for Distributed Storage Systems with Clusters and Separate Nodes

Abstract

The optimal tradeoff between node storage and repair bandwidth is an important issue for distributed storage systems (DSSs). As for realistic DSSs with clusters, when repairing a failed node, it is more efficient to download more data from intra-cluster nodes than from cross-cluster nodes. Therefore, it is meaningful to differentiate the repair bandwidth… (More)
