Actually the GUI allows for SCVMM2012 to do hardware based SnapShot VM Creation. That is where the 1 VM per LUN restriction comes from. It relys on SMI-S which as a standard lets you control array LUN operations. If you are willing to open a Powershell prompt and kick off a powershell script, you can still support a CSV with Many VMs per LUN. This would be accomplished via Sub-LUN Clones, which is still not supported by SMI-S standard.
So to sum up…
Using the SCVMM 2012 GUI I can create hardware LUN snapshots and create instant VMs.
or
I can kick off my own PowerShell scripts that allow for SUB-LUN clones to support CSVs.
or
I can use SCVMM to copy my VM into place over ethernet in which case CSVs can still be supported but no longer instant.

Vijay,

Thanks for pointing out my erroneous interpretation of the SCVMMSSP2 documentation. I’ve updated this article to clarify that one VM per LUN is only a requirement when scripting.

Eric, thanks for going through our documents for the Self Service Portal 2.0. I would like to clarify that the section which you are referring to is talking about how to extend the action of creating a LUN. We will clean up the docs to make that distinction, but referring to that text and indicating that the SSP 2.0 is not compatible or does not support using CSV is incorrect. This section is about creating LUN’s for VM’s. CSV operates at a higher abstraction than this.
