7 Glossary of Terms

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

220LTO, LTO-2 HH feature that allow detection of the best transfer rate

 

to use for optimizing performance on the SCSI-bus.

Data Compression

There are two ways to compress data on tape. Through the software data

 

compression or using hardware data compression as on the Tandberg

 

LTO HH

Device Driver

A software program that enables a computer to communicate with

 

peripheral devices such as a hard disk or tape drives. Each type of device

 

needs a different device driver. Device drivers are stored on a computer's

 

hard disk and are typically loaded into memory at boot time.

EEPROM

Electrically Erasable Programmable Read Only. 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. LVD provides better stability and noise

 

immunity of the electrical signals on the SCSI-bus lines. LVD also

 

allows longer SCSI Bus length.

Overwrite

A method of recording over data previously written on tape without

 

performing a erase operation before.

PNP

Plug and Play. A hardware and software mechanism that provides an

 

automatic way for the system to self-configure system resources such as I/O

 

ports, IRQ, and DMA channels between PNP cards and other devices in the

 

system.

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.

LTO-1 HH, LTO-2 HH, LTO-3 HH specifications

Tandberg Data has long been recognized as a leading provider of innovative data storage and backup solutions, and their tape drives, specifically the LTO-1, LTO-2, and LTO-3 Half Height (HH) models, represent a significant advancement in data storage technology. These systems are designed to meet the demands of modern data management, balancing capacity, speed, and reliability.

The LTO-1 HH, introduced in 2001, marked a groundbreaking step in the linear tape-open (LTO) technology. It offered a native storage capacity of 100 GB and a compressed capacity of up to 200 GB. The tape drive featured a data transfer rate of 20 MB/s, allowing for efficient backup processes. One of the key technologies in the LTO-1 was its use of ultral Linear Tapes, which helped in maintaining the integrity of data over extended periods. The built-in data compression capabilities also contributed to the efficient storage of large volumes of data, making it suitable for small to medium-sized businesses.

Building on the success of the LTO-1, the LTO-2 HH was launched, significantly enhancing performance with a native capacity of 200 GB and a compressed capacity of up to 400 GB. The data transfer rate improved as well, reaching 40 MB/s. The LTO-2 introduced the concept of WORM (Write Once, Read Many) technology, which added a layer of security by ensuring that data could not be tampered with after being written. This was particularly important for industries requiring regulatory compliance. Enhanced error correction and data integrity features were also hallmarks of the LTO-2, ensuring reliable long-term data storage.

The LTO-3 HH followed suit with even greater advancements, providing a native capacity of 400 GB and a compressed capacity of 800 GB, along with a data transfer rate of up to 80 MB/s. Its improved track layout and data encoding methods further enhanced performance and reliability. Additionally, LTO-3 introduced the partitioning feature, which divided the tape into virtual partitions for more efficient data management, allowing users to access data faster. The data encryption capabilities introduced with LTO-3 provided enhanced security, protecting sensitive data during backup and storage.

Together, these Tandberg Data LTO tape drives showcase a remarkable evolution in data storage technology, offering robust solutions that cater to businesses of all sizes. Their reliability, security features, and substantial data capacities ensure that organizations can efficiently manage their growing data storage needs in an increasingly digital world.
