IBM LTO2 Ultrium Full Height Tape Drives

IBM Ultrium LTO 2 18p9047
The IBM LTO2 FH Tape Drive Models L23 and H23 are high-performance, high-capacity data-storage devices that connect to and provide additional storage for supported servers. Designed to perform unattended backups as well as to retrieve and archive files.

IBM LTO2 FH Tape Drive Models feature:

  • Native storage capacity of 200 GB per cartridge (400 GB at 2:1 compression)
  • Native sustained data transfer rate of up to 35 MB per second (70 MB per
    second at 2:1 compression)
  • Burst data transfer rate of 160 MB per second for Model L23
  • The IBM LTO2 FH Tape Drive Models are equipped internally with the
    IBM Ultrium 2 Tape Drive.
  • Library drive versions are also available in a Fibre version

IBM LTO Ultrium drives share advanced technologies. Advanced multi-track recording capabilities, state-of-the-art
magneto-resistive (MR) flat lap heads and a surface control guiding system are designed to work together to
support extremely high recording densities.

The flat lap head is designed to help improve contact between the
read/write recording elements and the tape, supporting high-quality recording and read-back of your data. The
surface control guiding system guides tape across the read/write recording heads, using the surface of the tape and
not the tape edges.

This feature is intended to help improve the longevity of the tape while minimizing the chance
of physical damage to the tape media. Error-correction code (ECC) helps support data integrity and a Statistical
Analysis and Reporting System supports preventive diagnostic reporting, helps determine drive and media status
and helps improves drive and system availability.

IBM Ultrium 2 drive enhancements, compared to Ultrium 1 and other tape drives, include 200GB native capacity
(400GB at 2:1 compression) for double capacity and 512 data tracks to help achieve higher capacities
and throughput.

Digital speed matching (DSM) helps support higher throughput, especially for smaller and
uncompressible files. Power management (sleep mode) helps lower power requirements and thus can help reduce
operational costs, while channel calibration customizes read/write channels for optimum performance.

IBM also manufactures these tape drives for other OEMs such as Dell, Tandberg and others
