Abstract
The disclosed computer-implemented method for selecting a set of storage nodes from a plurality of storage nodes for use in reconstructing data on a faulted node in an erasure-coded system may include determining an average read access latency for a first set of storage nodes, detecting a storage failure a storage node, selecting a subset of the first set of storage nodes, such that the average read access latency for each of the storage nodes within the subset has a lower average read access latency than at least one other node (or as many as all the other nodes) of the available storage nodes, and reconstructing data that was stored on the failed storage node from the subset of the first set of storage nodes. During reconstruction, each of the nodes multiplies their data chunk by a coefficient and transmits the resulting product to an initiator node.
