IBM 3581 H23 Ultrium 2 HVD SCSI 7 Slot Autoloader

The IBM 3581 TotalStorage Ultrium Tape Autoloader models offer high capacity, performance, and technology designed for the midrange open systems environment. The 3581-H23 incorporates 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 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). With 7 Cartridge slots the H23 is capable of up to 2.8TB total capacity. 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 IBM 3581 Model H23 comes with an HVD Ultra SCSI attachment.
