Data Protection Suite perpetual software

Hi Team, 

I am finding a backup solution with 80TB (On-prem) và 40 TB (OCI Cloud) ---> 120 TB, I want to use PowerProtect Data Domain DD6400 with Tape to store the data, and use Data Protection Suite perpetual software as a backup software. I have question that: what is requirement of server that DPS software installed in (about CPU, RAM, Network, ...) 

Thank you!!!
