Windows 2012 R2, Storage Server, iSCSI, VHDX, Hyper-V Cluster.

Hey Guys

I recently setup a new storage server (WIndows 2012 R2, iSCSI and 2x Hyper-V Hosts. I have a question about "VHDX Drives" presented to a VM host, and then creating a VM (which uses vhdx) onto the presented "VHDX drive". I put this post on technet but no luck. (Bottom of page) - that is nested VHDX's.  


So here is what I have created:

1) Several LUNs created as "Diskname.vhdx"
2) Those LUNs are then presented to both my VMhosts
3) I created a Hyper-V Failover Cluster (2 VM hosts)
4) Then I presented my newly provisioned LUNs out and started setting up VMs.

Here is my question though, since an iSCSI "Drive" is basically just a VHDX file, and since VMs are basically stored on VHDX files.
Am I not creating a VHDX within a VHDX? Is that right way to do this? I realize my question may sound stupid, but in the past I simply created a VHD file on standard HDD. Now I am basically nesting vhdx's. ?

Thanks,
Robert
