3.9.2 SCSI-bus Termination – Internal Tape Drives

The SCSI-bus cable must be terminated in both ends according to SCSI specifications. If the tape drive is the last device on the bus, the bus must be terminated within 10 cm of the tape drive connection.

Tandberg LTO HH tape drives have a combined SCSI-LVD/SE interface embedded. The PC-98 Specification specifies that the termination of the SCSI-bus system is a part of the SCSI-cable and not a part of the SCSI-device.

For internal devices, a SCSI-cable with an integrated terminator or a separate terminator applied to the end connector of the cable, 10 cm from the last device must be used.

3.9.3 SCSI-bus Termination – External Tape Drives

If the Tape drive is the only device on the external SCSI-bus, it must be terminated using the external SCSI termination provided with the solution.

If other external device(s) is/are present, the Tandberg LTO HH tape drives can be installed in any position on the SCSI-bus. The Tandberg LTO HH tapes drive must be terminated if installed at the end of the SCSI-bus. See figure 3.7:

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.
