Overview
The new IBM TotalStorage(TM) Ultrium Tape Autoloader 3581 Models L23 and H23 offer high capacity, performance, and technology designed for the midrange open systems environment. These models incorporate a single Linear Tape-Open (LTO) IBM TotalStorage Ultrium 2 Tape Drive, which more than doubles tape drive performance over the generation 1 LTO Ultrium Tape Drives (Ultrium 1), up to 35 MB/sec native data transfer rate (70 MB/sec with 2:1 compression). In addition, with the use of the new IBM TotalStorage LTO Ultrium 200 GB Data Cartridge, the Ultrium 2 Tape Drive has the capability of writing twice as much data, up to 200 GB native capacity (400 GB with 2:1 compression). IBM Ultrium 2 Tape Drives can read and write original LTO Ultrium Data Cartridges at original Ultrium 1 capacities and with an improved performance of up to 20 MB/sec native data transfer rate (40 MB/sec with 2:1 compression). The Model L23 comes with a LVD Ultra160 SCSI attachment, while the Model H23 comes with a HVD Ultra SCSI attachment, for connection to a wide spectrum of open systems servers.
Other Ultrium 2 Tape Drive enhancements:
o Digital speed matching - to adjust the drive data rate with the host, which reduces backhitching and improves throughput performance
o Power management - to reduce power consumption
o Channel calibration - to customize each read/write data channel for optimum performance
o Separate writing of multiple filemarks - to improve performance when writing multiple files
o Larger internal buffer - the internal buffer size is 64 MB, double the buffer size of the Ultrium 1 drives
o Faster drive speeds - faster data access time, reduced rewind time, reduced cartridge load time, and faster cartridge fill time compared to the Ultrium 1 drives
The Ultrium Tape Autoloader 3581 is an external stand-alone or rack-mountable unit, similar to previous models of the 3581 autoloader, that incorporates a single IBM LTO Ultrium tape drive. The Ultrium Tape Autoloader 3581 capacity is seven tape cartridges, providing a media capacity of up to 1.4 TB (2.8 TB with 2:1 compression) data storage per unit.
