Abstract
An apparatus, system, and method are disclosed for reconfiguring an array of solid-state storage elements. The method includes determining that one or more storage elements are unavailable to store data. The storage elements are configured in an array of N storage elements that each store a portion of a first ECC chunk and P storage elements that store first parity data corresponding to the first ECC chunk. The method includes generating a second ECC chunk comprising at least a portion of the data of the first ECC chunk. The method includes storing the second ECC chunk and associated second parity data across (N+P)−Z storage elements where 1≦Z≦P.
