Abstract
Recent research has demonstrated the potential benets
of building storage arrays that understand the le systems
above them. Such “semantically-smart” disk systems use
knowledge of le 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-
ences when building database-aware storage. We nd
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.
