One or more storage units must be created on each PowerProtect DD system that is enabled for BoostFS. Storage units are accessible only to applications with the username that owns the storage unit. One username owns each storage unit, and the same username can own multiple storage units. PowerProtect DD administrators can also use existing DD Operating System (DDOS) CLI commands to create and manage storage units used by BoostFS.
The application passes the username and password to BoostFS, and DD Boost passes them to the PowerProtect DD system when attempting to connect to the PowerProtect DD system. The PowerProtect DD system then authenticates the username and password. The username and password can be shared by different applications.
