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. 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.
Service door
The door on either the 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 SAN is 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.
Universal drive sled (UDS)
A sheet metal case that houses LTO or SCSI drives in the drive clusters.
WORM
The Scalar i2000 library supports write once, read many technology in
LTO-3 and LTO-4 tape drives. WORM allows non-erasable date to be
written once and provides extra data security by prohibiting accidental
data erasure.
