Licensing Specs for LTO-6 Available in August, 2012
Native Capacity 2.5TB/Compressed 6.25TB and Transfer
Rates 160MB/s Native and 400MB/s Compressed
The vast amount of data being handled and protected by storage managers and
media professionals increases each and every day, driving the need for
cost-effective, reliable and compatible solutions that retain and protect data.
To address this, storage managers are turning to tape as a way to address their
storage needs.As a result, the LTO Program Provider Companies, HP, IBM
and Quantum announced that LTO technology has been helping to protect critical
data assets for 12 years.
More than 4 million LTO drives have been
shipped since the beginning of the program. Another milestone is expected to be
met by the end of this quarter as more than 200 million LTO cartridges will have
been shipped to organizations big and small since the format's inception. This
translates into more than 80,000PB (uncompressed) of storage capacity worldwide.
The amount of data that is stored on tape media continues to increase
dramatically, and the need for compatible, cost effective tape backup and
archive solutions remains an important part of the IT infrastructure.
Licensing specifications for the LTO Ultrium Generation 6 tape drive mechanisms
and media are planned to be available in August, 2012. The specifications are
expected to call for supporting a tape cartridge storage capacity of up to
6.25TB compressed, more than double the compressed capacity of the previous
generation, and tape drive data transfer rates of up to 400MB/s compressed
(Assumes 2.5:1 compression achieved with larger compression history buffer
available beginning with LTO Ultrium Generation 6 drives.)
The LTO
Ultrium Generation 6 format is designed to continue to provide core
functionality to enable broader use of the technology in a range of solutions.
The format includes partitioning functionality, enabling users to present a
tape-based file system with the use of LTFS. When combined with hardware-based
encryption and WORM functionality, LTO Ultrium Generation format 6 products are
designed to deliver a range of safe, secure and portable data storage options
for backup and archive.
The LTO Program continues to drive innovation in
the tape storage industry with significant enhancements to LTO performance
attributes while continuing to provide backwards compatibility and interchange
standards. Each new generation of LTO tape has offered customers substantial
increases in capacity and throughput as well as new capabilities opening the
doors for new applications and use-cases.
Since the introduction of the
partitioning feature in the LTO Ultrium Generation 5 format and the public
availability of LTFS software, tape is easier to use and a component not only
for backup but also for long-term data retention.
