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
