This is the best I've been able to come up with.
It isn't pretty.
Usually when I find myself making something this convoluted, I ask
myself if I'm actually solving more problems than I'm creating.
Anyway, here's some code. Enjoy.

It's not 100% clear to me from your sample data exactly what
you're trying to achieve.
Reading between the lines though, for each server, you want to
calculate the number of volumes?
What do you want to count as a 'volume'? Each block device?
Partition? PV? LV? Filesystem? Something else?
And do you need to do this using a statically defined var, or is
that just illustrative? It's highly likely that you can pull the
data you need from setup/facts and calculate the values you need
based on that.
