HP StoreEver ESL G3 Tape Libraries - Manual (Page 262)

Latchhook The latches used to lock the printed circuit blades into place when they are inserted into the I/O
management unit or library management module.
Library
Management
Console (LMC) Library Management Console (LMC) The management software client for the library. You can
use the LMC either locally from the OCP operator panel on the control module or remotely through
a web browser running a Java applet.
Library
Management
Module (LMM) The connectivity interface for the three blades that provide intelligence and connectivity to the
library through the control module. The management control blade (MCB), robotics control unit
(RCU), and library motor drive (LMD) blades are installed in the LMM.
Linear Tape-Open
(LTO) A media technology that is open format. LTO comes in two formats, Accelis and Ultrium. Ultrium
is the high capacity implementation.
Management
Control Blade
(MCB) The library controller board, which resides in the LMM. The MCB has I/O ports for Fibre Channel,
Ethernet, serial, and SCSI.
Partition A partition is a logical portion of the physical library that is viewed by the host as if it is a complete
library. Partitions present the appearance of multiple, separate libraries for purposes of file
management, access by multiple users, or dedication to one or more host applications.
Picker The robotic hand portion of the accessor assembly that handles cartridges.
Service door The door on a control module, or standard or high density expansion module that provides access
to the I/O management unit, LMM, power supplies, drive sleds and other components.
Write Once Read
Many (WORM) The ESL G3 tape library supports write once, read many technology in LTO-4 and later tape
drives. WORM allows a non-erasable date to be written once and provides extra data security
by prohibiting accidental data erasure.
X-axis The horizontal position of the robotic accessor assembly.
Y-axis The vertical position of the robotic accessor assembly.
