Abstract
Determining and using deduplication estimates may include: determining two deduplication sample indexes (DSIs) for two logical device sets each including one or more logical devices, determining a Jaccard Similarity for the two DSIs, wherein the Jaccard Similarity denotes a measurement of similarity and mutual deduplication between the two logical device sets; determining, in accordance with one or more criteria, whether the two logical device sets should be located in different data storage systems or a same data storage system that performs data deduplication, wherein the one or more criteria uses the Jaccard Similarity in determining whether to locate the two logical device sets in the same data storage system or the different data storage systems; and responsive to determining that the two logical device sets should be located in the same data storage system, locating the two logical device sets in the same data storage system.
