Smart Scale architecture pools together a set of DD Restorers (DDRs) into a group under the data center wherein all DDRs are managed by DDMC for space balancing. The actual placement of the backup object is in one of the DDRs in the System Pool which is done by Smart Scale services.
Note: Smart Scale supports DDOS 7.8 and higher. Smart Scale supports the following models DD9900, DD9400, and DD6900.
The DD Namespace VM is a virtual machine that is deployed from the PowerProtect DD Management Center UI which provides support for data protection applications to the DDRs in the system pool where Mobile Storage Units reside.
The following figure provides a high-level graphical representation of the Smart Scale architecture.
