Original Press Release:
IBM TotalStorage Ultrium Tape 2U Autoloader 3581 Models L28 and F28 Incorporate the IBM TotalStorage LTO Ultrium 2 Tape Drive Doubling Capacity and Performance
Overview
The new IBM TotalStorage® Ultrium Tape 2U Autoloader 3581
Models L28 and F28 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 previous generation LTO Ultrium 1 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 L28 comes with a LVD Ultra160 SCSI attachment, while the
Model F28 comes with a Native Switched Fabric 2 Gbps Fibre
Channel attachment, for connection to a wide spectrum of open systems servers.
The Ultrium Tape 2U Autoloader 3581 is an external 2U stand-alone or rack-mountable unit that incorporates a single IBM LTO
Ultrium 2 tape drive. The Ultrium Tape 2U Autoloader 3581 capacity is eight tape cartridges, providing a media capacity of up to 1.6 TB (3.2 TB with 2:1 compression) data storage per unit.
Other Ultrium 2 Tape Drive functions include:
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
Key prerequisites
Appropriate levels of host softwarem are required to attach the Ultrium Tape 2U Autoloader 3581 with IBM LTO Ultrium 2 Tape Drives to selected IBM eserver iSeries(TM), AS/400®, IBM eserver pSeries®, RS/6000®, RS/6000 SP(TM), IBM eserver xSeries®, Netfinity®, HP, Sun, Windows(TM) 2000, Windows 2003, Linux, and other UNIX® and PC servers. Refer to the Technical information section for details.
