The SmartDedupe&SmartCompression technology in Huawei Oceanstor all-flash storage simultaneously calculates similar fingerprints (SFP) and weak hash fingerprints (FP) when writing data. If the fingerprint already exists in the local fingerprint table, online deduplication is performed; If it is new data, perform compression and save similar fingerprints, and then perform background deduplication processing.
