Cinder has always used a wiki page as the source of our
support matrix. Unfortunately the wiki gives us no way
to ensure that the information is accurate and makes it
harder to track changes. Moving to using the
sphinx-feature-classification library solves some of these
problems.
* It provides a programatic way to document driver support.
* It allows us to ensure that documentation is updated with
changes.
* It will provide a snapshot of the state of driver support
for a release at the time of release.
This matrix will serve as the truth for Cinder's driver support.
The existing wiki will be kept for historical purposes but I will
make a pointer to this new documentation and indicate that no
changes should be made to the wiki in the future.

Cinder Driver Support Matrix
The following support matrix reflects the drivers that are currently available or are available in Cinder's driver tree at the time of release.
Note
This matrix replaces the old wiki based version of the Cinder Support Matrix as there was no way to ensure the wiki version was properly maintained. The old matrix will be left for reference but this matrix should be treated as the correct state of Cinder.
Required Driver Functions
There are a number of functions that are required to be accepted as a Cinder driver. Rather than list all the required functionality in the matrix we include the list of required functions here for reference.
- Create Volume
- Delete Volume
- Attach Volume
- Detach Volume
- Extend Volume
- Create Snapshot
- Delete Snapshot
- Create Volume from Snapshot
- Create Volume from Volume (clone)
- Create Image from Volume
- Volume Migration (host assisted)
Note
Since the above functions are required their support is assumed and the matrix only includes support for optional functionality.
