US Patent 11620270 Representing and managing sampled data in storage systems

Example implementation relates to generating a database for a set of entities associated with sampled data units of a storage system. A first data structure in the database maps, in a bit vector, each entity with a sampled signature of a set of sampled signatures. The set of sampled signatures are associated with the sampled data units. The set of entities associated with the set of sampled signatures are managed using the first data structure.
