Glossary
Active
Termination
Enhanced SCSI termination that provides better stability and noise immunity of the electrical signals on the
SCSI bus lines.
ALDC
Adaptive Lossless Data Compression. A hardware data compression method.
ASPI
Advanced SCSI Programming Interface. Standard SCSI software that acts as a liaison between host
adapters and SCSI device drivers. ASPI enables host adapters and device drivers to share a single SCSI
hardware interface.
Auto
sensing
PowerVault LTO-2-024 feature that allows detection of the best transfer rate to use for optimizing
performance on the SCSI bus.
EEPROM
Electrically Erasable Programmable Read Only Memory. An integrated circuit typically used to store
configuration information.
GUI
Graphical User Interface. Software which interacts with the user.
ID
See SCSI ID.
LVD
Low Voltage Differential. A SCSI interface that provides better stability and noise immunity of the electrical
signals on the SCSI bus. LVD also allows longer SCSI bus length and improved data rates.
RWW
Read While Write. All Tandberg tape drives automatically and internally read the data just being written to
the tape to avoid writing to bad block.
SCSI
Small Computer Signaling Interface. The PowerVault LTO-2-024 utilizes the SCSI Ultra160 interface which
allows for a transfer rate of up to 160 MB/sec on the bus.
SCSI ID
A unique identifier assigned to SCSI devices that enables them to communicate with a computer when they
are attached to a host adapter via the SCSI bus. Each SCSI host adapter board has eight available SCSI
IDs with numbers 0 through 7 (or 0 through 15 for Wide SCSI adapters). Usually the host adapter itself is
assigned SCSI ID 7.
SLDC™
Streaming Lossless Data Compression. The hardware data compression method specified as the standard
for the two Ultrum tape formats and thus used with the PowerVault LTO-2-024 tape drives.
HBA
Host Board Adapter. The SCSI interface board located in the server/PC
