Glossary
This glossary consists of terms unique to the library along with some storage industry terminology.
Access door Refers to the doors on either the control module or expansion module from which
you can access the magazines and accessor assembly.
Capacity on
demand (COD) A library feature that enables users to have a large physical library, but users
pay only for what capacity they are currently using. License upgrades enable
more capacity to be added without a system interruption.
Control
management
blade (CMB) A version of the MCB that has no I/O ports for Ethernet, SCSI, serial, or Fibre
Channel. It is the controller board for the I/O management unit in expansion
modules.
Control module The first component of the library. It consists of an library management module,
cartridges, drives, power, and an I/E station.
Data path One of the many possible paths that data can move over in the storage area
network environment, potentially involving many components or connections
between initiators and targets that have been set since the initial configuration
occurred.
Drive pooling Drives to be held in a pool (or pools) of drives. You can specify policy settings
for the drive pools to configure how each pool will react to a drive failure and
load balancing.
Drive sled position A slot where a Fibre Channel or SCSI drives reside in the control module or
expansion module in one of the two drive clusters. There are six drive sled
positions in each of the two drive clusters.
Encryption Key
Management
(EKM) A generic term used to encompass any encryption key management solution.
Ethernet Expansion
Blade (EEB) Provides Ethernet connectivity to 6 Ethernet drives. This connectivity is to the
library internal Ethernet and should not be connected to an external Ethernet
source.
Expansion module Expansion modules enlarge the library configuration by adding modules for
additional media storage. You can add up eleven expansion modules to a library
configuration. The first seven expansion modules may contain optional hardware,
such as additional drives and I/E stations.
I/E station A door on the access door of the control module (or expansion modules) that
contains magazines into which cartridges can be imported into or exported out
of the library.
All single door I/E stations are numbered starting with 1 at the control module.
All double door I/E stations are numbered with a number and a letter--for example
