Introduction
The family of IBM LTO Ultrium Tape Drives for Lenovo (Machine Type 6160) is external, stand-alone or rack-mountable tape drives that contain an LTO Ultrium 7, Ultrium 6, or Ultrium 5 Tape Drive that is designed for the heavy demands of backup tape storage. The drives deliver IBM tape reliability and performance at a cost-effective price.

TS2270 Model H7S incorporates the LTO Ultrium 7 Half-High SAS Tape Drive. TS2260 Model H6S incorporates the LTO Ultrium 6 Half-High SAS Tape Drive. TS2250 Model H5S incorporates the LTO Ultrium 5 Half-High SAS Tape Drive. These tape drives use a dual-port 6 Gbps SAS interface for connection to a wide range of servers.

The LTO Ultrium Tape Drives from Lenovo are excellent choices if you use tape drives that require larger-capacity or higher-performance tape backup. The TS2270, TS2260, and TS2250 Tape Drives are an excellent choice for tape backup solutions for Lenovo System x® and ThinkServer® servers.

These offerings can satisfy the wide range of your end-to-end IT infrastructure needs, including handheld devices, notebooks, personal computers, servers, storage, networking, services, management software, and financing.

The IBM LTO Ultrium Tape Drives include the following IBM LTO Ultrium features:

Dual-stage head actuator

The 16-channel actuator (LTO Ultrium 5 and 6) and 32-channel actuator (LTO Ultrium 7) provide precision head alignment to help support higher track density and improved data integrity.

- Independent tape loader and threader motors and positive pin retention

These technologies help improve the reliability of loading and unloading a cartridge and retain the pin, even if tension is dropped. An independent loader motor that is coupled with the positive pin retention causes the tape to thread with a higher level of reliability.

- Graceful dynamic braking

If there is a power failure, reel motors maintain tension and gradually decelerate instead of stopping abruptly, which helps reduce tape breakage, stretching, or loose tape wraps during a sudden power outage.

- Servo and track layout technology

There are 3584 data tracks in Ultrium 7, 2176 data tracks in Ultrium 6, and 1280 data tracks in Ultrium 5. The high-bandwidth servo system features a low mass servo to help more effectively track servo bands and improve data throughput with damaged media in less-than-optimal shock and vibration environments.

- Surface Control Guiding Mechanism

IBM patented Surface Control Guiding Mechanism guides the tape along the tape path in the Ultrium 7, 6, and 5 Tape Drives. This method uses the surface of the tape (rather than the edges) to control tape motion. This configuration helps reduce tape damage (especially to the edges of the tape) and tape debris, which comes from the damaged edges and can accumulate in the head area.

- Giant Magneto Resistive (GMR) head design

IBM LTO Ultrium Tape Drives use GMR head technology with beveled contouring for reducing striction and friction. This head design was demonstrated in enterprise tape products to help minimize contact, edge damage, debris accumulation, and wear on the tape as it moves over the read/write heads.

- Digital speed matching

The LTO Ultrium Tape Drives perform dynamic speed matching to adjust the drive's native data rate as closely as possible to the net host data rate (after data compressibility is factored out). This matching helps reduce the number of backhitch repositions and improve throughput performance.

- Robust drive components optimized for automation environments

To help enhance reliability and prolong the life of the drives, some of the most robust components available are used, such as an all metal clutch, steel ball bearings in the loader, robust leader block design, and a single circuit card.

- Power management

The power management function of the Ultrium 7 and Ultrium 6 Tape Drives controls the drive electronics to be completely turned off or in a low-power mode when the circuit functions are not needed for drive operation.

- Adaptive read equalization

This equalization automatically compensates for dynamic changes in readback signal response.

- Dynamic amplitude asymmetry compensation

This compensation dynamically optimizes readback signals for linear readback response from MR read head transducers.

- LTO Data Compression (LTO-DC)

The Ultrium LTO uses LTO-DC, which is an implementation of a Lempel-Ziv class 1 (LZ-1) data compression algorithm. LTO-DC is an extension of Adaptive Lossless Data Compression (ALDC) and an improvement over previous IBM lossless compression algorithms. IBM patented "Scheme-Swapping" compression looks ahead at incoming data and determines the most efficient storage method (ALDC or pass-through mode) to help optimize data compression and increase data throughput.

- LTO Cartridge Memory (LTO-CM)

Contained within the LTO Ultrium data cartridge is the LTO-CM, which is a passive, contactless silicon storage device that is physically a part of the cartridge. The LTO-CM holds information about that specific cartridge, the media in the cartridge, and the data on the media. The storage capacity of the Generation 6 and 7 LTO-CM is 16320 bytes, which is double capacity of Generation 5 LTO-CM 8160 bytes. Communication between the drive and the LTO-CM is via a low-level RF field transmitted by the drive to the cartridge.

- Statistical Analysis and Reporting System (SARS)

The Ultrium Tape Drive uses SARS to help isolate failures between media and hardware. SARS uses the cartridge performance history that is saved in the CM module and the drive performance history that is kept in the flash EEPROM to help determine the likely cause of failure. SARS causes the drive to request a cleaner tape, mark the media as degraded, and indicate that the hardware is degraded.

- Highly integrated electronics that use IBM engineered copper technology

This technology reduces the number of components in the drive, helping lower chip temperatures, and reduces power requirements to deliver a more reliable drive. The sixth-generation drive electronics provide error correction of soft errors in the memory arrays in data and control paths.
