Does anyone know if an update is in the works to support Server 2016? I have always installed NetApp's DSM software in lieu of the Host Utilities Kit (my understanding is the HUK is optional if NetApp's DSM software is installed). Interestingly, the iSCSI for Windows Express Guide in 9.3 indicates the guide is only for Server 2012 or 2008, and it lists the NetApp DSM software as a requirement.
I just got off the phone with NetApp support. They confirmed that ONTAP DSM isn't supported for Server 2016 and higher. They recommend using the built-in Microsoft DSM and then Windows Host Utilities 7.1.
