HP StoreEver ESL G3 Tape Libraries - Manual (Page 278)

2A and 2B--the module number (1-8), with A as the left I/E station and B the
right.
I/O management
unit A management and connectivity interface for the library. The control module and
first seven expansion modules can have I/O management units installed. The
I/O management unit may contain a Control Management Blade (CMB) and
Ethernet Expansion Blades (EEB).
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.
Library Managed
(AMP) partition A partition in the ESL G3 that is like any other partition, except it is not visible
to any backup applications or hosts. Allows the library to be able to manage
the partition, rather than the backup application managing the partition.
A virtual partition that can be dynamically allocated to other, previously-created
standard partitions, all without disrupting host or application operation. AMP
magazines are presented to host applications as part of a standard partition,
but AMP magazines appear as "inaccessible" until they are assigned to a normal
partition. AMP may be thought of as “thin provisioning” for a tape library. Both
the Partition license and the AMP license are required to enable AMP. Both
licenses are sold on a per-library basis.
Linear Tape-Open
(LTO) A media technology that is open format. LTO comes in two formats, Accelis and
Ultrium. Accelis is the fast access implementation, while 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.
HP Enterprise
Secure Key
Manager (ESKM) The HP encryption key management solutions that supports HP LTO-4 and LTO-5
FC tape drives.
Service door The door on a control module or expansion module that provides access to the
I/O management unit, LMM, power supplies, drive sleds and other components.
Storage area
network (SAN) A dedicated, high-performance network whose primary purpose is the transfer
of data along FC or high-speed Ethernet connections between servers, interconnect
devices, and storage peripherals.
