The only offical requirements I have seen from NetApp are as follows:
- VSC 5.0.1 Beta
- VASA Provider 6.0 for clustered Data ONTAP Beta
- clustered Data ONTAP 8.2.1
However, the beta software no longer works with VVOL.
VSC and VSAP VP 6.0 will be released 'very soon' and will provide full support from what I understand.
