• SCSI—for robotics other libraries
• NDMP—for NDMP robotics
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.
