Abstract
In this paper we describe research that has been on-going within
our group for the past four years on semantically-smart disk sys-
tems. A semantically-smart system goes beyond typical block-
based storage systems by extracting higher-level information
from the stream of traffic to disk; doing so enables new and in-
teresting pieces of functionality to be implemented within low-
level storage systems. We first describe the development of our
efforts over the past four years, highlighting the key technologies
needed to build semantically-smart systems as well as the main
weaknesses of our approach. We then discuss future directions
in the design and implementation of smarter storage systems.
