I have two Tiers of storage

Tier 1 SSD 

Tier 2 10k disks

I think I know the answer but with data progression can the storage see any more granular than the VHD?

I.e. Does it see the usage of a VHD or can it see that a file in the VHD has a high read write requirement?

 

Currently running a Hyper v cluster with VHD's saved to a volume on the iSCSI, will I need to make volumes for each server and directly attach to the VM??
