Abstract:
We present a new form of storage virtualization based on block-level address
remapping. By allowing the host system to manipulate this address map with a
set of three simple operations (clone, move, and delete), we enable a variety
of useful features and optimizations to be readily implemented, including
snapshots, deduplication, and single-write journaling. We present a prototype
implementation called Project ANViL and demonstrate its utility with a set of
case studies.
