Yes. In NexentaStor, this is the Auto-CDP plugin.
For OpenSolaris, this was demonstrated by Jim Dunham a few years ago at:
http:blogs.sun.com/AVS
However, that blog seems to be gone. You can google "zfs avs" for more
pointers, but be
aware of PSARC/2010/060 EOF of Availability Suite (AVS), which is not a public
case in
the ARC caselogs
http://arc.opensolaris.org/caselog/PSARC/2010/
Finally, products which do block-device-level replication have a tendency to be
slow
because you are serializing a parallel activity. Be sure to test with your
configuration
to ensure your performance goals are achievable. There are some architecture
choices
which can help somewhat, but Amdahl's Law still applies.
