that accompanies the library.
Flex Bays (for DBAs
or TBAs)
Depending on requirements, flex bays let you increase the number of drives or
amount of media installed in the library. Flex bays can accommodate additional
drive bay assemblies (DBAs) for increased performance or TeraPack Bay
Assemblies (TBAs) for increased storage capacity.
Note: T380 libraries with TS11xx technology or T10K tape drives do not
contain flex bays. The flex bays are replaced by DBAs or shelves.
TeraPack Bay
Assemblies (TBAs)
or shelves
The TBAs or shelves increase the storage capacity of the library. Each TBA
contains four chambers, each of which accommodates a single magazine. If the
library has only one DBA installed, TBAs occupy the flex bays.
Note: T380 libraries with TS11xx technology or T10K tape drives do not
contain TBAs. TBAs are replaced by DBAs or shelves.
Drive Bay
Assemblies (DBAs)
The DBAs house the drives and any optional controllers installed in the library.
Each DBA accommodates up to four drives and provides the electrical and
internal interface connections for the drives. See Tape Drives on page 44 for
information about the drives used in the library.
Each DBA also includes a controller bay for a RIM or QIP to the right of the drives.
A minimum of one DBA must be installed in the library. One additional DBA
can be installed in the flex bay above the first DBA in the T200 library; two
additional DBAs can be installed in the T380 and T680 library.
Notes:
Any drive or controller bays that do not contain components must have
covers installed to maintain proper air circulation throughout the library and
to protect internal components.
The library does not support placing an LTO drive in Drive Bay Assembly
position 1 if there is a TS11xx technology or T10K drive in Drive Bay
Assembly position 2, or in Drive Bay Assembly position 3 if there is a TS11xx
technology or T10K drive in Drive Bay Assembly position 4.
LCM A dedicated on-board library computer module runs the BlueScale software
that controls all aspects of library operation. To learn more, see Library Control
Module (LCM) on page 39.
