Abstract: Iered storage is the important way for Intelligent Data Management.It can effectively balance access relationships between storage resources and variety data,and maximize the overall performance of the storage system.Howe-ver,the judgment of hotspot data is a bottleneck for tiered storage in process of data classification.Proposing a Fuzzy Logic-based Model of tiered storage (FLM) which uses the data characteristics as the input variable that reflect hot and cold level of data.Then,FLM uses the fuzzy logic to analyze data characteristics for getting output variable,and it can smooth the boundary of non-hotspot and hotspot.Experimental model analysis indicates that FLM can make the smoothness of data migration and reduce shake problems in data management.

Key words: Intelligent data management,Tiered storage,Fuzzy reasoning
