Licensing Specs for LTO-6 Available in August, 2012

Finally only native 2.5TB and 160MB/s

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 Technology Provider Companies (TPCs), HP Corporation, IBM Corporation and Quantum Corporation, announced that LTO technology has been helping to protect critical data assets for 12 years.

According to a recent study by IDC more than 4 million LTO drives have been shipped since the beginning of the program (Source: IDC Worldwide Tape QView, March 2012.) Another milestone is expected to be met by the end of this quarter as Santa Clara Consulting Group anticipates that 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," said Robert Clark, SVP, Data Protection Group, at Quantum. "The TPCs continue to drive tape standards forward with development of new generations of LTO Ultrium technology delivering significant innovations in capacity and performance while maintaining vendor interchange and backward compatibility for long-term investment protection."

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," said Robert Amatruda, research director, data protection and recovery at IDC. "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.

"With the introduction of LTFS for our video archive, we’ve been able to utilize LTO-5 tape to significantly reduce our storage costs, improve our scalability, ease of use and reliability over our previous systems," said Jamie Morganstern, BAMM.TV‘s director of operations. "Today, BAMM.TV producers and editors can search for files stored on LTO tapes as if it were NAS storage and easily pull projects and footage that we worked on more than a year ago."

Added Morganstern: "We can rely on the LTO tapes. Now if a hard drive goes down, we’re not worried and scrambling to have it restored. I know I can simply request the LTO tape and be ready to roll."

How to License LTO Ultrium Technology

  • The LTO Program has historically offered several different license packages – from enhanced packages that provide the specifications and licenses to manufacture LTO Ultrium products, to basic packages providing LTO format specifications.
  • Buyers seeking LTO Ultrium format-compliant products should look for the LTO Ultrium format compliance verification trademarks on both tape drives and data cartridges. Storage and media manufacturers interested in licensing LTO formats may obtain information by contacting the LTO Program.

Comments

The new main specs of LTO-6 are below what was formerly announced by the LTO consortium. For uncompressed capacity and transfer rates, it was supposed to be 3.2TB and 210MB/s for LTO-6, it's now 2.5TB and 160MB/s, or an increase of only 67% and 14% respectively, in comparison to 1.5TB and 140MB/s for LTO-5.

Native Figures Without Compression

 Gen  Capacity*  Transfer Rate*
 LTO-5  1.7TB  140MB/s
 LTO-6  2.5TB  160MB/s
 Growth   67%    15%

    Figures With Compression*

 Gen  Capacity*  Transfer Rate*
 LTO-5    3TB  250MB/s
 LTO-6  6.25TB  400MB/s
 Growth  108%    60%

 * Maximum
 ** 2.0:1 for LTO-5, 2.5:1 for LTO-6

Today's highest capacity HDD is native 4TB.

Next one LTO-7 is supposed to be native 6.4TB and 315MB/s - but no date has been revealed by the consortium -, to be followed by LTO-8 (12.8TB, 472MB/s), the last one on the current roadmap.
