Yes, I have a CCISS setup here, I am already aware of all of this.

I really do want to separate hardware RAID controllers from regular old
disks, though.  That's the point of all the storage filtering - show
different types of disks in different panes so you can quickly and
easily sort them out.

I agree that the name-based approach is pretty bad, especially as we
find other types of disks.  We've played this game before.  However,
we're going to need to find another approach.
