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 im-
prove performance, availability, and even security in ways
that are precluded in a traditional storage system archi-
tecture.
In this paper, we study the applicability of semantically
smart disk technology underneath database management
systems. For three case studies, we analyze the differ-
