All four library robotic control protocols are implemented in both the General Media Agent and in the NDMP Media Agent.
Drive control
Any Data Protector client system configured to control a drive in a library (regardless of the drive control protocol and platform used) can communicate with any Data Protector client system configured to control the robotics in the library (regardless of the robotics control protocol and platform used). Thus, it is possible to share drives in any supported library among Data Protector clients systems on various platforms using various robotic and drive protocols. The NDMP Media Agent is needed only on client systems controlling the backup of an NDMP server (on client systems configured for NDMP dedicated drives). In all other cases the two Data Protector Media Agents are interchangeable.
Table 10 on page 166 show the Data Protector Media Agent (the General Media Agent or the NDMP Media Agent) required on client systems configured for drive control of a library with drives shared among multiple client systems.

Robotic control
A Data Protector client system controlling the library robotics can have either the General Media Agent or the NDMP Media Agent installed, regardless of the type of drive protocol (NDMP or SCSI) used with the drives in the library.
