Each configured FSE library has one Library Agent running. The Library Agent handles actions in the FSE
library, such as loading and unloading media, and library inventory rescan.
An FSE implementation which only uses FSE disk media do not have FSE libraries.
FSE drive
An FSE drive is a tape drive inside an FSE library, configured in the FSE implementation. It is used to read
to and write from FSE media.
Supported drive types are:
• LTO Ultrium 1, LTO Ultrium 2, and LTO Ultrium 3
• LTO Ultrium 3 WORM
For further information on the supported drive models, see the latest support matrices.
FSE implementation options
Due to its modular structure FSE allows several implementation options. It can be set up as a consolidated
implementation or as a distributed implementation of servers and clients, each of those being run on any of
the supported platforms. For limitations regarding platform support in distributed FSE environments, see the
latest support matrices.
Additionally, FSE provides support for multiple tape libraries. The number of libraries that can be
connected to one FSE server depends on the number of slots for Fibre Channel and SCSI cards on the
machine hosting the FSE server.
Consolidated implementation
The simplest application is the “all in a box” configuration, where all FSE components reside on the same
machine.
Figure 3 Consolidated FSE implementation
This consolidated FSE implementation integrates the functionality of both FSE server and FSE client in a
single machine. It has a direct connection to secondary media and hosts an arbitrary number of HSM file
