The IBM TotalStorage 3580 Tape Drive is an external stand-alone or rack-mountable unit and contains a Linear Tape-Open (LTO) Ultrium 3 tape drive designed for the heavy demands of backup tape storage. It is supported for Small Computer Systems Interface (SCSI) attachment to IBM e server p5 and pSeries, IBM e server i5 and iSeries, IBM e server, AS/400, RS/6000, HP, Sun, UNIX, and PC servers.
The 3580 Tape Drive Model L33 incorporates third-generation IBM LTO Ultrium technology. The 3580 Tape Drive Model L33 offers the following significant improvements over the Ultrium 2 Tape Drive:
- Maximum tape drive throughput data rate performance is more than doubled, up to 80 MB/sec native data transfer rate. Data tracks are now written 16 at a time. IBM Ultrium 3 Tape Drives can read and write, at 8 data tracks at a time, LTO Ultrium 2 Data Cartridges at Ultrium 2 rates, and read LTO Ultrium 1 Data Cartridges at Ultrium 1 rates.
The tape cartridge capacity is doubled over the Ultrium 2 Data Cartridge up to 400 GB native physical capacity (800 GB with 2:1 compression), with the use of the new IBM TotalStorage LTO Ultrium 400 GB Data Cartridge. This is achieved by increasing the linear density, the number of tape tracks, and the media length. The tape itself is an advanced metal particle tape developed to help provide durability and capacity.
Ultrium 2 cartridge compatibility — The Ultrium 3 Tape Drive can read and write on Ultrium 2 cartridges.
SCSI Ultra160 LVD attachment — The Model L33 comes with a SCSI Ultra160 LVD attachment, for connection to a wide spectrum of open system servers. They are supported on AIX, OS/400, i5/OS, Sun Solaris, HP-UX, Microsoft Window 2000, Windows 2003, Linux, and other open systems.
New dual stage 16 channel head actuator — designed to provide precision head alignment to help support higher track density and improved data integrity.
New independent tape loader and threader motors and positive pin retention — designed to help improve the reliability of loading and unloading a cartridge, and to retain the pin even if tension is dropped. With an independent loader motor coupled with the positive pin retention, the tape threads with a higher level of reliability.
Adaptive read equalization — automatically compensates for dynamic changes in readback signal response caused by cartridge interchange and head wear.
Dynamic amplitude asymmetry compensation: dynamically optimizes readback signals for linear readback response from magneto resistive read head transducers.
Larger internal data buffer — There is a 128 MB internal data buffer in the Ultrium 3 Tape Drive as compared to a 64 MB internal data buffer in the Ultrium 2 Tape Drive.
Highly integrated electronics using IBM engineered copper technology — designed to reduce the total number of components in the drive, lower chip temperatures, and reduce power requirements, helping to provide for a more reliable drive. The generation 3 drive electronics also incorporate on-the-fly error correction of soft errors in the memory arrays in data and control paths.
Graceful dynamic braking — In the event of power failure, reel motors are designed to maintain tension and gradually decelerate instead of stopping abruptly, helping reduce tape breakage, stretching, or loose tape wraps during a sudden power-down
