PowerStore provides data-reduction capabilities such as zero-detect, compression, and deduplication. Data reduction is integrated into the PowerStore architecture and is always active. During periods of high write activity, PowerStore may defer the deduplication of data, and devote those resources to servicing the client workload. During periods of low activity, PowerStore will use excess resources to re-examine any data written during these periods for duplicates, to regain any space savings that were not initially realized.
