HP StorageWorks Enterprise Modular Library E-Series User Guide (AH876-96001, September 2007)

lift drive assembly A component of the robot that moves the table assembly vertically among the
library mod ules.
lift drive pulley A component of the lift drive assembly used to move the table assembly vertically
along the lift pole to slots and tape drives.
lift-flex cable The cable that carries control and power signals to the table assembly. This
cable automatically adjusts to the position of the table assembly in the library.

cables
Four cables used to lift and lower the table assembly amo
ng the library modules.
l
oad port
A
device in the library that allows an operator to insert or remove tape
cartridges during library operations.
logical library A virtual representation of a physical library. Also called virtual library partition.
LTO Linear Tape-Open. A technology that creates tape drives and tape cartridges
based on common specification, licensing, and compliance standards and
allows tape device users to use tape products and tape cartridges from various
sources. Ultrium 460 tape drives (LTO-2) are HP’s second generation of LTO tape
drives and the Ultrium 960 tape drives (LTO-3) are third generation tape drives.
magazine A removable array that holds tape cartridges and is placed into the load port.
PCI Peripheral component interconnect. The PCI bus typically runs a t speeds of 33
MHz or 66 MHz and is usually 32 bits wide. This means that it passes 32 bits
of data simultaneously as if down 32 separate wires. Some of the most recent
computers include wider 64-bit PCI buses, and already certain very high-end
video capture cards offer improved performance if connected to a 64-bit PCI
bus.
picker The portion of the picker assembly that grasps and holds a tape cartridge.
picker assembly A part of the library robot whose function is to grasp tape cartridges and move
them bet ween slots and tape drives. A b ar code scanner on the hand assembly
reads tape car tridge volume labels.
put An activity in which a robot places a tape cartridge into a slot or tape drive.
PWA Printed wiring assembly.
reach mechanism A component of the robot that moves the gripper to get or put a tape car tridge
atadesignatedlocation.
robot An electro-mechanical device that transports tape cartridges to and from
locations in the library.
robotics unit The unit that includes the robotics components and that controls the movement
of the robot between sl
ots, tape drives, and load ports.
RS-232C Short for Recommended Standard-232C, a standard interface approved
by the Electronic Industries Association (EIA) for connecting serial devices.
This standard is for asynchronous transfer between computer equipment and
accessories. Data is transmitted bit by bit in a serial fashion. The RS-232
standard defines the function and use of all 25 pins of a DB -25 type connector.
slot The location in the library in which a tape cartridge is stored.
slot database The tape cartridge and slot records collected by the library inventory.
suspension cabl e One of four cables used to raise and lower the table.
