Quantum Scalar 1000 Reference Guide

Scalar DLC Reference Guide 243
Robot
The automatic system that consists of a manipulator that is moving back and
forth as well as up and down on the rails to access all library slots and move
the cartridges from/to them. Also contains a Barcode reader to identify the
accessed cartridges.
Robotic accessor
Same as Robot.
Rule
Same as Event rule.
Scalar DLC log
The list of notification messages that describe the Scalar DLC working process.
Can be viewed from outside even when the Scalar DLC software itself is
stopped.
Scanner
Same as Barcode reader.
Scratch cartridge
The data cartridge that is considered as empty and ready-to-write.
Scratch medium
Same as Scratch cartridge.
Scratch pool
A logical set of scratch cartridges (single media type only). Each data cartridge
assigned to the scratch pool will be considered as scratch.
SCSI
Small Computer System Interface. A widely used interface with the large
carrying capacity. Requires additional hardware (SCSI adapter(s), cables, etc.)
and software (SCSI Target Mode driver).
SCSI coordinate
Element (slot) physical coordinate in SCSI format (0 - 65535).
Single-aisle
The Physical library with a single robot.
Single-port adapter
The Adapter that contains a single port to send/receive commands.
Slot
The part of the physical library that receives a cartridge. There are three
groups: Storage slot, Insert/eject slot (mailbox), and Drive.
Storage area
All available storage slots in the library.
Storage slot
The slot is designed to keep a cartridge as long as it is required.
Storage tower
A device that consists of storage slots. Its capacity is larger than of the linear
storage (for example, DLT-tower contains up to 18 rows of slots, and DLT-
shelve only 6).
If the library is dual-aisle, there always is at least one storage tower that can be
accessed by both robots and therefore called shared. However the tower can
be non-shared, too.
Tape
A synonym for Cartridge. All tapes are cartridges, however some cartridges are
not tapes.
Tape device
Same as Physical library.
Target
Depending on the adapter properties, each Target has a number of LUNs. That
means each Target can be connected to this number of the devices, or
represent such a number of connected devices to the client as well.
