Hi tmiller_hockey,
We should have you covered with the new Orion Storage module + VMAN that is soon to be released.

SRM will trend and forecast your NetApp volumes/aggregates/etc. and allow you to get a view of your environment wide capacity.
Have you got your Hyper-V environment added to Virtualization Manager?
If I were you I would keep an eye open for announcements on these two forums:
