Future of Linear Tape-Open (LTO)

Future of Linear Tape-Open (LTO)

In today’s scenario, so much content is being produced that handling it is the biggest challenge every company is facing. It won’t be wrong to say that every moment becomes a data for further reference from time to time. And where there is data, there is a need for its storage and preservation. The importance is one notch higher in broadcasting and media industry. There is already an ocean of heritage content to be taken care of and the volume is only increasing day by day. Innovators, over a period of time, have come up with various technologies to manage and optimize content to its best possible condition.

It all started in late 1990’s when technology providers Hewlett Packard, IBM Corporation and Quantum Corporation developed and finally introduced the first generation of Linear Tape-Open (LTO), a magnetic tape storage technology in the year 2000 which could hold 100 GB of data in a cartridge. The standard form factor of LTO technology is known by the name Ultrium which is highly scalable and adaptable on multi-platforms like MAC, Linux, and Windows.

LTO has proved revolutionary in terms of data storage with its outstanding performance, capacity, and reliability, combining the advantages of linear multi-channel, data compression, track layout and error correction.
Due to its high success outcome and market demand, regular enhancements have been done and 2017 could see the launch of its 8th generation which can hold data up to 12 TB in a cartridge of the same size. Although, between generations, there are strict compatibility rules clearly defining which drives and cartridges can be used together.

WHY HAS THE INDUSTRY TURNED TO LTO?

The word ‘Tape’ may sound old school but breakthrough enhancement features have made LTO the most suited backup storage medium. Every company needs a storage solution which is high on speed and capacity and has adequate protection levels. Content is available in various forms. LTO Ultrium, being an open format technology provides its users to source data from multiple platforms and store it in a very convenient and easily restored format.
LTO, with each version, have come up with better speed resulting in quick access and recovery. Capacity to store data has increased manifolds. Functionalities like WORM and data encryption provide adequate protection of the valuable data thus by preventing it from getting tampered.

LTO based archiving also proves cost-effective in terms of reduced energy bills and also since storage capacity is ever increasing with each new generation thereby further reducing the cost.

WHAT DOES LTO-8 OFFER?

LTO-8 was recently revealed in 2017, two years after LTO-7. It is obvious to get attracted to the new improved version but many factors go into this big decision making.If we look at the specifications, LTO-8 offers 12 TB of raw data capacity which is 50% more than what is provided by its previous version. The head channel count also goes up to 32 from 16. The compressed transfer rate has also increased from 750 MB/s to 1180 MB/s. The encryption and WORM feature remains the same.

A new feature which aces up LTO-8 is its ability to increase the cartridge capacity of LTO-7 by 50%. LTO-8 drives can also read and write to LTO-7 tapes thus by saving on the huge investments already made.2

So, before making any decision to consider the switchover, a lot of factors have to be considered in terms of budget, usage, last upgraded time and also to what extent the capabilities of new tapes can be leveraged.

To sum up, we can say that when we think of tapes as a storage and recovery solution, we are focussing on future demands of the ever-increasing volume of data which can be stored and accessed in an environment which is secured as well as cost-effective. And LTO, with its roadmap and growth capabilities, promises to be able to endure Big Data challenges with its continuous breakthroughs.

Cultural institutions preserving heritage in digitization era

Cultural institutions preserving heritage in digitization era

Culture forms the backbone of each place and its people are identified by their cultural uniqueness. Some great thinkers started preserving it over the time to keep it alive even after thousands and thousands of years.

Today, each country or community has so much heritage of such great value, it is unimaginable. There is audiovisual history, artifacts, material objects, paper preserves, books and the list of items goes on. This heritage is only adding up with each passing day. Museums, libraries, galleries, cultural institutions are full of priceless content.

When it all started off, no one must have ever thought of the challenges humankind will face to take care of them and keep them alive for generations and generations to come. But slowly and gradually, these institutions started facing issues as far as the quality of these preserves was concerned. With changing times and depleting environmental conditions, it became very difficult to upkeep with the quality of each heritage. The need to secure these valuables became such a worrisome issue and needed a permanent and a highly durable solution to it.

WORLD OF DIGITIZATION AND ITS CHALLENGES

A lot of research went into it and Digitization provided the one-stop solution to all problems these institutions were facing. It brought new life to the ever-diminishing rich cultural heritage of our very existence. But it was just a start. With the onset of digitization journey, cropped up, many challenges.

What to Digitize & How to Store

Not everything could be digitized or preserved. There were various forms in which our history existed and that too in varied conditions. Selecting a thing which was possible to revive and then deciding on how to preserve it became the first and foremost task of digitization specialists. The content had to be selective, holds significance with the motive of preservation and be in a revival condition.

Another concern for the custodians of these historical assets is storing the items once a digital copy has been created. It is a speculated decision of investing resources to store old physical items, such as obsolete audio-video material, or frail paper items or let them go after they have been archived digitally.

The Copyright Issue

Another major issue which affected many digitization projects was The Copyright Issue which had to go through a lot of clearances. In such cases, there was the high risk of content being frail or sub judice. Google Books Library Project is a well-known example for when it started digitizing books of US libraries in 2002, never had they thought what lay ahead. In 2005, members of Association of American Publishers and Authors’ Guild brought proceedings of copyright infringement against Google. It was only after a long battle that in late 2013, Google’s activities were protected as fair use.

Money Matters

Cost is another major issue. Any digitization project – audio, video, or manuscript etc. – involves a huge investment in terms of technology and highly skilled manpower. A fair amount of budget needs to be allocated which depends largely on the content, in its present analog form and how will it be converted digitally. Initially, the main purpose to digitize content was to create a repository. Further commercial use was not something high on agenda. But, over the period of time, its future viability became a major deciding factor before undertaking any project.

SOME OF THE SUCCESSFUL DIGITIZATION PROJECTS

Overcoming all hindrances and obstacles, many digitization projects were undertaken and accomplished the feat.

To name a few, The Star East Asian Library at Columbia University holds a unique collection of over 200 Chinese “paper gods” which were conserved and digitized.

Digitizing history of Australian Museum and South Australian Museum in 2010 is another example wherein digitizing workstations were built to reduce cost and increase productivity. They also enjoyed the luxury of increased budgets from time to time seeing the outcome.

In 2015, a major digitization project was undertaken by University of Michigan Biological Collections to digitize close to 50,000 natural history specimens.

Many libraries namely Library of Congress, The British Library, Australian Islamic Library, South Carolina State Library, German National Library of Medicine, National Library of Indonesia, National Library of Whales are few of the names who have successfully preserved their rich heritage. Furthermore, world-class universities also went the digital way to not only preserve their assets but also made them available for references.

THE IMPACT & ROAD AHEAD

Consistent and sustainable efforts showed positive results and slowly and gradually, all institutions started adopting digitization or digital archiving to save and preserve their assets. Now, it has become a worldwide phenomenon and every place, big or small, has adopted technology to give a new life to their collection.

It is even envisaged that in years to come, the word ‘Digital’ would have no meaning of its own. It would actually mean ‘Default’. Digital libraries and repositories have helped our cultural organizations in not only preserving the vast history but has also aided in its accessibility to a wider audience thus by satisfying its commercial viability as well.

Digitization seems to be the need of present and future to preserve our glory and pass it on to our coming generations for them to understand their roots, their forefathers’ journey of life and evolvement of the human brain. It helps in beautifully integrating the past into the present and together advance towards the future.
