Tandberg Data	LED Bahavious

NOTE 1:

Some of the states are difficult to see due to short duration.

NOTE 2:

LEDs are also used to indicate fatal errors at an early power-up stage. This is accomplished by turning the LEDs ON one-by-one:

•The Ready LED as early as possible (after CPU-initialization).

•The Activity LED before initialization of serial communication interface (DACI).

•The Clean LED after PROM checksum test.

•The Fault LED after the CPU and SRAM Tests

After all LEDs are lit there is no controlled stop, and if the next LED-phase (flashing Ready LED) never appears, the system has crashed somewhere in the remaining part of the POST/PUI Part1. All LEDs are steady on for approximately 2 seconds.

NOTE 3:

•The Clean LED steady ON indicates that a head cleaning operation is recommended (the Drive is still fully operational with this LED steady ON) the LED is triggered after 100 hours of tape running time has elapsed, if the Media Management Algorithm has detected severely degraded write performance, or if a hard read/write error has occurred. The LED is not turned off by a power cycle. The LED is reset when cleaning has completed successfully. The Clean LED is also turned on during Head Brush operaion (no sticky).

NOTE 4:

•When a diagnostic activity leads to media operations (load/eject, read/write etc.) the LED behavior changes to a behaviour that corresponds to this kind of operation in a normal activity, but with Ready LED still flashing.

NOTE 5:

•The Fault LED will flash to indicate an unrecoverable error. An unrecoverable error is an error condition that results in the drive not being able to function unless initiator, operator, or service intervention is applied. An unrecoverable drive failure is usually the result of a hardware error condition. One of the following actions will be needed to clear the flashing Fault LED:

•Hard SCSI Reset

•Cartridge Emergency Eject

•Power Cycle

•Retry Firmware Download

An unrecoverable cartridge (media) failure is usually the result of a defective cartridge, media, or cartridge tate and will require the drive to eject the cartridge (if possible) to clear the flashing LED.

NOTE 6:

•Firmware download failed and the drive is not functional. The drive boot code is in control and the firmware download should be retried. The drive can be identified via an INQUIRY command and is thereby bootable while in this state.

NOTE 7:

•The Fault LED will be on solid to indicate an over temperature (tape temperature > 47°C). If a tape is present it will be ejected. The LED will remain on until one of the following conditions are met:

•The drive temperature goes below the preset maximum, and a new data or leaning cartridge is inserted

•The drive temperature goes below the preset maximum, and the tape drive is power cycled.

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.
