services on the FSE server. User data from these remote file systems is transferred to the FSE server and
recorded on the corresponding disk media or tape media in the attached tape library.
Figure 2 Distributed FSE implementation
NOTE: Communication between the components of a distributed FSE implementation is based on the
CORBA technology (omniORB). A reliable bidirectional network connection from each of the external FSE
clients to the FSE server is an essential prerequisite for a reliable operation of a distributed FSE
implementation. Communication between FSE implementation components through a firewall is neither
supported nor tested.
Distributed implementation is sometimes called distributed system with separate server and clients.
IMPORTANT: In a distributed FSE implementation, if the FSE processes on the FSE server are restarted,
you must restart the FSE processes on all external FSE clients to resume the normal FSE operation.
Mixed implementation
Mixed implementations consist of a consolidated FSE system with additional clients connected to it.
External FSE clients, which can run on different operating systems, are physically separated from the
integrated server and client.
External FSE clients connect to the consolidated FSE system through LAN and host additional HSM file
systems. They run only processes that provide functionality for managing these HSM file systems and
communicate with major services running on the consolidated system. User data from HSM file systems on
clients is transferred to the consolidated FSE system and recorded on disk media and/or tape media in the
attached SCSI tape library.
NOTE: See the note about omniORB for distributed implementations above.
