Re: hardware or software based disk ownership?

In the current versions, it does not help. The goal of flexgroups is to
distribute.
DBs and VMDKs are generally large(r) files. Flexgroups work with files and
will distribute a file to a constituent.
It will monitor space usage to help with the distribution.

When large files are in play, it will drop a chunk onto a flexgroup member
but that plays a little on the algorithms for placement of normal (smaller)
files.
