A computer system includes a storage device and a data storage controller coupled to the storage device. The controller is configured to for each of a plurality of data objects stored in a storage device, determine, based on one or more attributes corresponding to usage of the data object, a probability of the data object being deduplicated; store within a first fingerprint table, fingerprints of data objects with the highest probability of being deduplicated; store within a second fingerprint table, fingerprints of data objects with a lower probability of being deduplicated than the data objects having fingerprints stored in the first fingerprint table; and search fingerprints of the first fingerprint table to determine whether a fingerprint for a data object associated with a write request matches a fingerprint for any of the data objects in the first fingerprint table."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Utilizing multiple fingerprint tables in a deduplicating storage system","description":"A system and method for managing fingerprint tables in deduplicating storage systems.
