Linear Tape-Open technology was developed by three leaders in the storage industry -HP, IBM, and Seagate - who
brought together their combined expertise in tape technology to develop an entirely new format based on the best of
existing technologies. Because LTO Ultrium technology was a new format, it required no cumbersome support of
legacy formats, so it could be designed without compromising on reliability or performance. The LTO Program, a
consortium of the three technology provider companies, has developed a well-defined four-generation roadmap,
which has been executed right on schedule, with the first generation of Ultrium drives and media released in 2000 and
the second generation in 2002.
Ultrium 1 tape drive technology uses a linear format of 384 tracks, writing eight tracks simultaneously. Ultrium 2 tape
drive technology uses a linear format of 512 tracks, writing eight tracks simultaneously. The data is written in a
serpentine pattern; the tape reverses direction after each set of eight tracks is written. This provides higher density
recording, enabling customers to lower costs and increase efficiency by storing more data on a single tape in an
industry standard format. Tapes written on the HP StorageWorks Ultrium 215 and Ultrium 230 tape drives can be
interchanged directly with each other and with Ultrium 1 and 2 tape drives from HP and other vendors. Tapes written
on the HP StorageWorks Ultrium 460 tape drives can be interchanged directly with Ultrium 2 tape drives from other
vendors.
LTO data compression (LTO-DC) is an enhanced version of Advanced Lossless Data Compression (ALDC) hardware
compression. Compression is automatically turned "off" if the compressed data would cause an overall expansion in
data size, hence optimizing the available capacity on the media. The system is used in both Ultrium 1 and Ultrium 2
products.
The decision about what next technology you should buy into should be based on your future, not your past,
investment. Choose the Ultrium format when you need the following advantages:
Maximum reliability, capacity and performance
Compatibility with a broad range of operating systems and servers (e.g., a mixed system environment)
A legacy-free technology that uses the best attributes from a wide range of tape technologies without any
compromises for backward compatibility requirements
A solid roadmap for future generations of the technology
An open format available from multiple vendors
Lowest media cost of any 'superdrive' tape technology
An exclusive feature of HP Ultrium tape drives, data rate matching allows the tape drive to adjust its transfer rate to
the speed of host dynamically and continuously. Data rate matching keeps the data to the drive "streaming," reducing
the need to rewind the tape back and forth to wait for the host (the "shoeshining" effect). This feature brings two big
advantages:
It optimizes performance, getting the best performance possible for the environment, regardless of the speed of
the host or the network.
It reduces wear and tear on drive and media, thus increasing reliability.
With HP One-Button Disaster Recovery, you can quickly, reliably and simply restore your entire system just by inserting
the most recent backup tape and pushing one button on the tape drive. Your HP StorageWorks Ultrium tape drive will
restore your operating system, configuration, applications, drivers and data files. There's no longer a need to search for
software disks and manuals, plus with downtime reduced, the costs of recovery are minimized. There's no need to make
a new set of disaster recovery disks each time the network configuration is altered or a peripheral is added. Recovering
from a disaster manually at a stressful time makes for an error-prone process. The sheer simplicity of HP One-Button
Disaster Recovery means less human error. Backup and disaster recovery preparation - previously two separate tasks -
become one process. OBDR is simply the best disaster recovery product for small to medium systems. For a current list
of servers, workstations, and software that support OBDR, check the tape backup compatibility pages on our Web site

HP's test program for HP Ultrium media is probably the most thorough and comprehensive in the industry. HP
cartridges must satisfy an exhaustive battery of additional tests that relate directly to real life situations, where real data
and real businesses are at stake. Over 1 million test hours on media and drives per year ensure that HP cartridges will
always offer maximum reliability even in the most extreme conditions.
