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
