NDMP and Disk pools ( data domain ) lab setup

Hi Experts,

I need some suggestions, 

I have Netbackup master & Media 7.5 server on Redhat 6.5 box.Emulated Virtual tapes with virtual software on same box.

Additonally I have one more windows media server where drives are configured with iscsi.

Currently we have prod env with Datadomain. 

Is there anyway that I can simulate the Datadomain kind of setup in my test lab. I would also like to see if I can be able to simulate NDMP also.

Please guide me in simualting both of the above,so that I can do some R&D in my test bed and learn concepts.

Any ideas would be appreciated.

waiting for replies.

Thanks
