Data Protector on HPE StoreEasy installation

We have a strange request for a small environment. 
The environment consists of two esxi hosts and a vcenter. Several virtual machines are running on it.
There is also one HPE StoreEasy storage in the area.
The requirement is to install the Data Protector application on it.
As far as I've seen, it's absolutely possible.
I am interested which device LTU is used in that case (NDMP or advanced backup to disk or something else)

I used to be serious about this product. I still maintain a few sites with version 7 (due to TRU64 support) so I have no experience with new things, virtualization and licenses.
