<div>In that case, it is probably best to
transpose the table, with series included, the number of products
will yield too many columns to be workable.<br>

Also: Do blank spaces indicate "not supported" or "unknown"?<span><font color="#888888"><br>

<br></blockquote></div></div></div>So thanks for putting this together but this brings something up that I've been meaning to raise on the dev-list anyway. In my opinion it should be a requirement that for a driver to be accepted in Cinder it implements all of the functionality of the base LVM driver (ie all of the rows listed in the matrix here).<div>
<br></div><div>Having to go through and determine what feature is or is not supported per driver is EXACTLY what I want to avoid. If we go down the path of building a matrix and allowing partial integration it's going to create a huge mess and IMO the user experience is going to suffer greatly. Of course a driver can do more than what's on the list, but I think this is the minimum requirement and I've been pushing back on submissions based on this.</div>
<div><br></div><div>The only exceptions have been some of the newer Grizzly features, but that's only because we're moving those up to generalized cases that folks can inherit from if they use iSCSI. For those that want to do FC or AOE drivers however they're going to need to have a solution of their own. </div>
<div><br></div><div>My thought is there should be a simple list of back-end device and version and whether it's supported in Grizzly or Folsom or ..... All API features should be assumed available.</div><div><br></div>
