The hardware specifications for the primary storage server
depend on the platform and deployment size.
The primary storage server handles topology builds, data
presentation requests, and manages the storage server pool. You must
have one primary storage server for each TADDM deployment. You can
add additional capacity by deploying secondary storage servers.
