LTO Roadmap Now Through Generation 8
LTO Roadmap Now Through Generation 8 >> https://urllie.com/2ti6lT
The LTO Program first released its LTO Ultrium standard in 2000 with a capacity of 200 GB per cartridge compressed. Two decades later, the LTO Program released LTO generation 9, which supports tape cartridge storage compressed capacity of up to 45 TB* and tape drive data transfer rates of up to 1,000 MB/second*. At less than $0.01 per gigabyte, LTO has established itself as the storage medium of choice for long-term data archiving both on-premises and in the cloud.
The LTO Ultrium format is a powerful, scalable, adaptable open tape format developed and continuously enhanced by technology providers Hewlett Packard Enterprise (HPE), IBM Corporation and Quantum Corporation (and their predecessors) to help address the growing demands of data protection in the midrange to enterprise-class server environments. This ultra-high capacity generation of tape storage products is designed to deliver outstanding performance, capacity and reliability combining the advantages of linear multi-channel, bi-directional formats with enhancements in servo technology, data compression, track layout, and error correction.
The LTO Ultrium format has a well-defined roadmap for growth and scalability. The roadmap represents intentions and goals only and is subject to change or withdrawal. There is no guarantee that these goals will be achieved. The roadmap is intended to outline a general direction of technology and should not be relied upon in making a purchasing decision. Format compliance verification is vital to meet the free-interchange objectives that are at the core of the LTO Program. Ultrium tape mechanism and tape cartridge interchange specifications are available on a licensed basis.

According to the INSIC tape technology roadmap2, the potential for tape technology to meet robust capacity predictions over the next decade shows a clear advantage to HDD technologies. Current LTO and enterprise tape drives operate at areal densities that are about two orders of magnitude less than the latest HDD. That means it is possible to continue increasing capacity of tape technology at historical rates through to about 2030.
Generations 7 and 8 have been added to the LTO product roadmap, calling for native capacities of 6.4 TB and 12.8 TB, respectively. Specifications include a larger compression history buffer which tests show can increase compression to 2.5 to 1. This can allow compressed cartridge capacities of 8 TB for generation 6, 16 TB for generation 7 and 32 TB for generation 8, helping users to store more data in less space and address cost control objectives.
Tape drive data transfer rates are anticipated to increase by 50 percent with each new generation, with plans for generation 6 to provide native transfer rates up to 210 MB per second, generation 7 up to 315 MB per second and generation 8 up to 472 MB per second.
\"LTO compliant products have been a core part of storage solutions for over a decade due partly to a roadmap with a vision for future technology needs,\" said Rob Clark, VP of Business Operations at Quantum. \"With a clearly defined roadmap leading to the eighth generation, LTO Technology is addressing the growing demands of data protection in midrange to enterprise-class server environments.\"
LTO format generation 5 drives are designed with backwards-compatible read-and-write capability with Ultrium format generation 4 cartridges, and backward read capabilities with generation 3 cartridges, helping to protect investments and ease implementation.
It's a great idea for the LTO consortium to reassure the storage community with two coming steps, LTO-7 and-8, as the former roadmap was stopped at next LTO-6.First, remark that there is no date for the arrival of the upcoming LTO-6, -7 and -8. Normally, it's two years from one generation to the other. But for LTO-5, it was three years.Secondly, capacity is supposed to double for next generation, but it has to be demonstrated. LTO-5 was finally at 1.5TB, not 1.6TB if you compare with LTO-4 (800MB). That's the same for the transfer rate: 100% more between LTO-1 and -2, 100% between LTO-2 and -3, then down to 50% between LTO-3 and -4, and only 17% between LTO-4 and -5. Wait to be sure that it will be 50% between LTO-5 and -6, and the same percentage for LTO-7 and then LTO-8.Thirdly, we don't know which technologies (heads and media) are going to be used. But note that IBM researchers had demonstrated in January 2010 the ability to store 29.5 billion bits per square inch of data tape using the linear recording format based on Fujifilm Nanocubic technology incorporating BaFe particles, a step toward the potential of realizing a single tape cartridge capable of holding 35TB.Fourthly, the is no word of the compatibility between current LTO and the next ones. Normally it's R/W compatibility with the former version and read only with the two former generations. As tape is more and more considered as an archiving rather than a backup media, it means that users are obliged to migrate their data each four or five years. That's about the same period needed for hard disk drives. Five years is a very short period for archives and the roll media have to be verified regularly, around each two to three years.Continuing to make a comparison with HDDs, some problems of LTO will probably continue. The capacity is not growing fast enough. Today's LTO-5 is at native 1.5TB, HDD currently at 2TB. Prices of the tape drives and media are too expansive and their volume is less and less appropriated with smallest form factor already on the storage market. And for archiving, we don't agree with tape vendors that LTO is more reliable than disk (much more mechanics in the tape device, cartridges and drives not totally protected from the environment). And finally tape units use more power than HDDs, have good transfer rate but ridiculous access time. You will think I'm not a big fan of tape. It's true and I never was.
LTO-9, the latest LTO magnetic tape standard was announced in the Fall of 2020. In the last few weeks the first LTO-9 products became available. LTO 9 tape has a raw capacity of 18TB and compressed storage capacity at 2.5:1 of 45TB (50% more than the prior generation LTO-8 product). LTO 9 is part of a series of half-inch magnetic tape generations. LTO-9 has native data transfer rates of up to 400 MB/s. This is a 25% increase in data rate over LTO-8. LTO-8 tape is selling for about $6/TB ($0.006/GB) so, in volume, LTO-9 tape cartridges could sell for a similar price or $4/TB ($0.004/GB).
The LTO Program Technology Provider Companies Hewlett Packard Enterprise, IBM Corporation and Quantum LTO Holdings announce that Fujifilm Corporation and Sony Corporation completed interchange testing and achieved LTO Ultrium generation 9 format compliance, permiting these companies to use the LTO Ultrium generation 9 format trademarks on LTO products. Note that there was a significant lawsuit over a few years between Sony and Fujifim over LTO-8 technology.
Native capacities for Linear Tape-Open (LTO) cartridges will once again double with every successive generation, according to a new roadmap published this month by the group of companies behind the LTO spec.
While data generation and data storage are on ever-increasing trajectory, it was the expansion of the ransomware epidemic triggered in part by the COVID-19 pandemic that spurred demand for air-gapped storage methods like tape.
The standard form-factor of LTO technology goes by the name Ultrium, the original version of which was released in 2000 and stored 100 GB of data in a cartridge. The ninth generation of LTO Ultrium was announced in 2020 and can hold 18 TB in a cartridge of the same physical size.
As of 2020, nine generations of LTO Ultrium technology have been made available and five more are planned. Between generations, there are strict compatibility rules that describe how and which drives and cartridges can be used together.
Drives usually support variable-speed operation to dynamically match the data rate flow. This nearly eliminates tape backhitching or \"shoe-shining\", maximizing overall throughput and device/tape life.
In contrast to other tape technologies, an Ultrium cartridge is rigidly defined by a particular generation of LTO technology and cannot be used in any other way (with the exception of LTO-M8, see below). While Ultrium drives are also defined by a particular generation, they are required to have some level of compatibility with older generations of cartridges. The rules for compatibility between generations of drives and cartridges are as follows:
Within the compatibility rules stated above, drives and cartridges from different vendors are expected to be interchangeable. For example, a tape written on any one vendor's drive should be fully readable on any other vendor's drive that is compatible with that generation of LTO.
Depending on the generation of LTO technology, a single LTO tape should be able to sustain approximately 200-364 full file passes. There is a large amount of lifespan variability in actual use. One full file pass is equal to writing enough data to fill an entire tape and takes between 44 and 208 end-to-end passes. Regularly writing only 50% capacity of the tape results in half as many end-to-end tape passes for each scheduled backup, and thereby doubles the tape lifespan. LTO uses an automatic verify-after-write technology to immediately check the data as it is being written, but some backup systems explicitly perform a completely separate tape reading operation to verify the tape was written correctly. This separate verify operation doubles the number of end-to-end passes for each scheduled backup, and reduces the tape life by half. 153554b96e
