Abstract:Recent research has demonstrated the potential benefits of building storage arrays that understand the file systems above them. Such ``semantically-smart'' disk systems use knowledge of file system structures and operations to improve performance, availability, and even security in ways that are precluded in a traditional storage system architecture.In this paper, we study the applicability of semantically smart disk technology underneath database management systems. For three case studies, we analyze the differences when building database-aware storage. We find that semantically-smart disk systems can be successfully applied underneath a database, but that new techniques, such as log snooping and explicit access statistics, are needed.
