Hello,
The Hardware Universe is your friend here...
The link for vSphere 5.5 is https://mysupport.netapp.com/matrix/imt.jsp?components=65559;&solution=56&isHWU
The link for vShhere 6.0 is https://mysupport.netapp.com/matrix/imt.jsp?components=69924;&solution=56&isHWU
This will detail the supported software stack for each version, just click other components to narrow down the filer.
Any issues will be suppiled in the Alerts and Info buttons in the results page. I would just be careful to check whether you can upgrade direct to the version you're looking to install or you need 2 step upgrade, this will be in the Alerts as well as the Release Notes/Install Guide for the software.
Also, to confirm SMVI is not a seperate product and included within the VSC, incase you were looking 🙂
Hope this helps.
Thanks,
Grant.
