StoreEasy 1430 and VHDX format

Hi,

Please, I have  3 questions:

How can I create VHDX volumes with this model? This server comes with WSS 2012 Std.

Any experience with the functionality / performance / stability of SQL 2008 (cluster 2 nodes with Windows 2008 R2) and StoreEasy 1430 via iSCSI?

Is a best practice create the volumes with VHD format on a clustered environment?

Thanks in advance!
