Question 337
The SmartDedupe& SmartCompression technology in Huawei Oceanstor all-flash storage will calculate similar fingerprints (SFP) and weak hash fingerprints (FP) at the same time when writing data. If the fingerprint already exists in the local fingerprint table, it will perform online de-duplication; if it is new data, perform compression and save similar fingerprints, and then perform background deduplication processing.

② When the memory write cache reaches a certain water level, the data starts to be flushed down
③ Data writing based on RAM Write Cache
④ The small IO will be written to the SSD cache of the node first, and then written to the HDD after being aggregated into a large IO
