drive The device that the library uses to record data onto tapes.
drive cleaning A library feature that uses a cleaning cartridge to clean a tape drive.
drive module The entire assembly that houses the drive, including the metal housing and connectors.
ESD Electrostatic discharge. The release of static electricity from one conductor to another.
Ethernet A local-area, packet-switched network technology. Originally designed for coaxial cable, it is
now found running over shielded, twisted-pair cable. Ethernet is a 10- or
100-megabytes-per-second LAN.
event A significant library occurrence (such as drive errors, online/offline transition, drive cleanings,
and other information) that is listed in an automated log.
export The action in which the library places a cartridge into the cartridge access port so that the
operator can remove the cartridge from the library. Also called eject.
extension bars The power strips connected to the power distribution unit.
Fibre Channel A bidirectional, full-duplex, point-to-point, serial data channel structured for high performance
capacity. The Fibre Channel is an interconnection of multiple communication ports, called
N_Ports. These N_Ports are interconnected by a switching network, called a fabric, to a
point-to-point link, or an arbitrated loop. Fibre Channel is a generalized transport mechanism
with no protocol of its own. A Fibre Channel does not have a native input/output command
set, but can transport existing Upper Level Protocols (ULP) such as SCSI. Fibre Channel
operates at speeds of 200 MB per second. Fibre Channel operates over distances of up to
100 m over copper media or up to 10 km over optical links.
flash memory Firmware memory for the current and previous version of library firmware.
front door A door on the front of a library through which service personnel or operators can access the
interior of the library.
get An activity in which a robot obtains a cartridge from a slot or drive.
GUI Graphical user interface. Software that allows the user to control the library environment
through visual screens.
HBA Host bus adapter. A circuit board residing in the host system that handles requests to and from
the host system and the library.
host One or more computers that generate and communicate data to the library.
The capability that allows a component to be replaced while power to the component is
hot-swappable
maintained. This feature allows hardware maintenance actions and hardware upgrades to
proceed without disrupting subsystem availability.

HP (unit of measure) Horizontal pitch. A measurement of the width of a chassis. EML circuit card assemblies sitting
horizontally in card cages are measured vertically in these units where one HP is 5.08
millimeters (0.2 inches).
import The process of placing a cartridge into the cartridge access port so that the robot can insert it
into a storage slot.
