I wouldn't say it's ready for prime time, but much of the work was done
in Newton and some are merged in master and a few patches are still in
progress. One thing that remains to be done is to test with a variety
of makes/models of switches.

You can see the progress of the whole set of patches here:
https://bugs.launchpad.net/ironic/+bug/1526403

Snapshot support for Ironic instances is still a wishlist feature:
https://bugs.launchpad.net/mos/+bug/1552348

I think the closest you could get at this point might be to use
Cinder-backed boot volumes for your Ironic nodes. That would have
impacts on performance and network traffic. You could get snapshots
for just data by using Cinder volumes for non-boot mount points.
