HP EML E-series Tape Libraries - Manual (Page 108)

magazine A removable array that holds tape cartridges and is placed into the load port.
PCI Peripheral component interconnect. The PCI bus typically runs at 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 between
slots and tape drives. A barcode scanner on the hand assembly reads tape cartridge 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 cartridge at a designated
location.
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
slots, 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 cable One of four cables used to raise and lower the table.
table assembly A component of the robotics unit that carries the picker assembly vertically among the library
modules.
tape cartridge A container holding magnetic tape that can be processed without separating the tape from the
container. The library uses data and cleaning cartridges. These cartridges are not interchangeable.
tape drive An electromechanical device that moves magnetic tape and includes mechanisms for writing and
reading data to and from the tape.
tape drive
assembly An interface to control/monitor tape drive operation.
U A measure of chassis height. 1U in rack measurement is 44.45 mm (1.75 inches).
Circuit card assemblies using the cPCI standard use the Eurocard range of circuit card sizes,
where 3U cards are 100 x 160 mm (3.94 x 6.3 inches) and 6U cards are 230 x 160 mm (9.187
x 6.3 inches). The Interface Manager card is considered 4U wide with dimensions of 161.9 x
157.3 mm (6.4 x 6.2 inches).
World Wide Name
(WWN) A 64-bit integer that identifies a Fibre Channel port.
wrist A component of the hand assembly that rotates the hand horizontally.
