Protector internally redirects the robotic commands to the system that manages the
robotics.
Figure 47 Connecting drives to multiple systems
Control protocols and Data Protector Media Agents
The drives in the library must be able to physically connect to different systems that
have a Data Protector Media Agent (the General Media Agent or the NDMP Media
Agent) installed.
With Data Protector, there are two types of protocols used for drive control:
• SCSI—for SCSI or Fibre Channel connected drives.
This protocol is implemented in both the General Media Agent and in the NDMP
Media Agent.
• NDMP—for NDMP dedicated drives.
This protocol is implemented in the NDMP Media Agent only.
On the other hand, there are four types of protocols used for library robotic control:
• ADIC/GRAU—for ADIC/GRAU library robotics
• StorageTek ACS—for StorageTek ACS library robotics
