Abstract
A system identifies a data object, stored in a client, for replication. The system identifies a redundancy number associated with a protected amount of failed storage nodes. The system determines whether the total count of available storage nodes is at least two greater than the redundancy number. The system determines a distribution number that is at most the total count minus the redundancy number, in response to a determination that the total count of available storage nodes is at least two greater than the redundancy number. The system creates erasure code for the data object. The system allocates the distribution number of sections of a replica of the data object to a corresponding distribution number of available storage nodes and the redundancy number of sections of the erasure code to the redundancy number of available storage nodes, which excludes the corresponding distribution number of available storage nodes.
