SOSS: smart object-based storage system

Hints for storage system come from three aspects: the first is in combination with accurate file or directory attribute layout. The second is from existing file system and depends on user input. The third is from file content analysis. However in the SOSS (smart object-based storage system), object, a new fundamental storage component different from traditional storage unit (file or block), is introduced, and object provides ample hints for storage system, which can help with designing more intelligent (or smarter) storage system. This paper gives a brief introduction about SOSS, and some methods adopted in SOSS to achieve intelligence, such as pattern recognition method, predicting object properties method and an adaptive cache replacement policy (all are based on object attribute), are studied.
