We present the notion of a type-safe disk (TSD). Unlike a
traditional disk system, a TSD is aware of the pointer relationships
between disk blocks that are imposed by higher layers such as the file
system. A TSD utilizes this knowledge in two key ways. First, it
enables active enforcement of invariants on data access based on the
pointer relationships, resulting in better security and integrity.
Second, it enables semantics-aware optimizations within the disk
system. Through case studies, we demonstrate the benefits of TSDs and
show that a TSD presents a simple yet effective general interface to
build the next generation of storage systems.
