The PowerProtect Data Manager with IDPA solution has the following the minimum software requirements:
According to the architecture of PowerProtect Data Manager, for each policy, there is a Storage-Unit that is created on the embedded Data Domain system. You must ensure that you do not run out of Storage-Unit space on the embedded Data Domain system.
The following figure (from E-Lab Navigator) shows the maximum number of MTrees that can be created on the embedded Data Domain system and the total number of MTrees that can be active for both read and write operation.
Note: One MTree is always reserved for the IDPA backup server.
