Partitions
Partitions are virtual sections within a library that present the appearance of multiple, separate
libraries for purposes of file management, access by multiple Operators, or dedication to one or more
host applications.
Organizing the library into partitions divides the resources into virtual sections. If one of the resources
is not available due to a failure or other cause, the other partitions and their assigned components are
still available.
The StorageLibrary T40 can be divided into a maximum of four partitions. At least one tape drive and
one magazine must be assigned to each partition. The robotics, the import/export slots and the
cleaning slots are common resources to all partitions. For more information on partitions, see
Configuring Partitions .
Control Path
The “control path” tape drive is used to connect a partition to a host application. Only one tape drive
can be selected as the control path at one time. By default, the first tape drive assigned to a partition
is designated the control path. In the event that the control path connection to the host application
fails, you can select a new control path for the partition.
I/E Station
I/E station enables importing and exporting cartridges without interrupting normal library operations.
I/E station slots are located in either the lower left or the upper left magazine. The number of I/E slots
for the 40 slot library is user settable to 0 (none), 3 or 8. The number of I/E slots for the 24 slot library
is user settable to 0 (none) or 3.
The I/E slots are shared among all partitions. When a cartridge in an I/E slot is assigned to a partition,
only that partition can access that I/E slot.
Access to the I/E slot is managed through the front panel interface only.
Simple Network Management Protocol (SNMP)
The StorageLibrary T40 supports system monitoring via SNMP and SNMP Notifications.
Capacity on Demand (COD)
In StorageLibrary T40 libraries, LTO storage slots are licensed for use. At any time, Capacity on
Demand (COD) allows you to enable the unused storage slots within a library via an electronic license
key. The StorageLibrary T40 comes with 24 or 40 slots (two lower magazines) A StorageLibrary T40
with 24 slots can later be upgraded to 40 slots purchasing the Capacity On Demand (COD) license
key
Details about the COD license key:
The license key does not expire
Once a license key is installed it cannot be removed
The COD license key can be purchased as any other product from Tandberg Data.
To see your library’s current configuration and slot availability, open the home screen of the remote
management interface.
Once you receive the license key, enter it via the front panel of the library. When the license key is
entered, the total number of available slots in the library increases.
