Consider the following information when you are using multiple VLANs:
PowerProtect Data Manager supports only VGT mode (multi VLAN) unlike vProxy, which supports both VST (single VLAN) and VGT modes. Therefore, the UI does not show a selection for a port group for PowerProtect Data Manager.
No restrictions apply to the operation flow sequence. Any parameter can be edited to modify or add values for the defined parameters.
The DD series appliance network name can be different, but PowerProtect Data Manager and assets must reach the DD series appliance network. Using a proper naming convention helps.
Customers are responsible for ensuring that networks are reachable and configured correctly.
An old vProxy cannot be edited and attached to a VST or VGT port group. It must be reconfigured.
We recommend that you have PowerProtect Data Manager and the DD series appliance in the same VLAN; otherwise, proper gateway/routing must be established.
Search can only be done in the default VLAN.
PowerProtect Data Manager asset restriction (application and file system): If the assets of the same host/client are attached to different networks, those assets must be on a different policy.
