PowerProtect Data Manager 19.12 Administration and User Guide

Protection storage

Protection storage is the set of configured storage systems where PowerProtect Data Manager stores backup copies, replicated copies, and other important information. Protection storage can include any of the following:

• A DD system, including High Availability PowerProtect DD mode
• An instance of PowerProtect DD Management Center (DDMC) that manages multiple DD systems
• A DDMCSmart Scalesystem pool

The most up-to-date software compatibility information for PowerProtect Data Manager is provided by the E-Lab Navigator.

Observe the following information before you configure protection storage:

• Adding and configuring protection storage requires the Administrator role.
• You cannot add protection storage that runs incompatible versions of DDOS.
• You can only add the same protection storage system once, whether you specify the hostname, FQDN, or IP address.
• You cannot add a PowerProtect DD Management Center instance which has no managed DD systems.
• The first time that you add protection storage, PowerProtect Data Manager automatically configures and enables server DR. The first protection storage system is the default target. System recovery for server DR provides more information.
• Adding protection storage by hostname or FQDN provides maximum flexibility for future IP address changes. PowerProtect Data Manager uses DNS to resolve hostnames and FQDNs when you select these entries for the Management network interfaces. Should you later change the DNS mapping, PowerProtect Data Manager resolves the new address and directs Management communication there. Communication with the Data network is by IP address.

Protection storage is further divided into logical groupings that are called storage units, which hold related data and apply more detailed configuration options.
