Research scientists at IBM have recorded a new world record in tape storage – their fifth since 2006.
The new record of 201 Gb/in2 (gigabits per square inch) in areal density was achieved on a prototype sputtered magnetic tape developed by Sony Storage Media Solutions.
This new record areal recording density is more than 20 times the areal density used in current state of the art commercial tape drives, and it enables the potential to record up to about 330TB of uncompressed data on a single tape cartridge that would fit in the palm of your hand.
330TB of data are comparable to the text of 330mn books, which would fill a bookshelf that stretches slightly beyond the northeastern to the southwestern most tips of Japan.
Tape storage is currently the most secure, energy efficient and cost-effective solution for storing enormous amounts of back-up and archival data, as well as for new applications such as big data and cloud computing.
“Tape has traditionally been used for video archives, back-up files, replicas for disaster recovery and retention of information on premise, but the industry is also expanding to off-premise applications in the cloud,” said IBM Fellow Evangelos Eleftheriou.
“While sputtered tape is expected to cost a little more to manufacture than current commercial tape that uses Barium ferrite (BaFe), the potential for very high capacity will make the cost per TB very attractive, making this technology practical for cold storage in the cloud.”
IBM has worked closely with Sony Storage Media Solutions for many years and the results of this collaboration have led to various improvements in the media technology.
Innovations have included advanced roll-to-roll technology for long sputtered tape fabrication and better lubricant technology, which stabilises the functionality of the magnetic tape.
IBM has a long history of innovation in magnetic tape data storage. Its first commercial tape product, the 726 Magnetic Tape Unit, was announced more than 60 years ago. It used reels of half-inch-wide tape that each had a capacity of about 2MB.
The new areal density demonstration announced by IBM represents a potential increase in capacity of 165,000,000 times compared with the company’s first tape drive product.
Future-tech and IXAfrica: Full Life Cycle Expertise
Future-tech is unique among data centre consultancies for a number of reasons. Not only does the Reading-based firm have high levels of expertise in markets ranging from Helsinki to Johannesburg, but Future-tech offers services across the complete life cycle of a facility.
“We are involved with projects from the initiation to completion,” explains James Wilman, Future-tech’s CEO. “We go from initiation phase - which could mean the site selection process or technical due diligence for a merger or acquisition - all the way through establishing the brief, the various design stages, construction oversight, commissioning, operation, end of life cycle replenishment, and can start right back at the beginning with refurbishment.”
While some factors, like the facility requirements for major tenants, remain the same no matter where you are, Wilman explains that “it's the environmental conditions, construction methodologies, supply chain, and skill sets available in different locations that vary, and that makes this a very interesting job.”
Future-tech was selected by IXAfrica as the life cycle design strategic partner for its hyperscale campus project in Nairobi, Kenya. Wilman explains that, over the past year, Future-tech has been leveraging its strong local knowledge, working closely with Kenyan architects and engineers, and collaborating with both Guy Wilner and Clement Martineau, to help IXAfrica successfully deliver Kenya’s largest hyperscale data centre.
“Future-tech did its first project on the African continent in 2012 in Kenya. I've been involved in the data centre space there for a long time, and have known Guy for a number of years through projects and interaction in Europe,” says Wilman. “As the IXAfrica project came into being, Guy and I spoke about it as he knew that we were already quite familiar with the area. We assisted out with the initial planning and project design, and the relationship really grew from there.”
Wilman adds that the experience helping Future-tech support the IXAfrica project has been hard-won. “It's been a steep learning curve, figuring out how to work in Africa. Some of our earlier projects were quite challenging, but we're fortunate to be at a point now where working throughout the region feels really comfortable,” he explains. “One of the things about Nairobi - which we found out when we were working on our first project in the city back in 2012 - is that, because it's about 1,200 metres above sea level, the altitude actually de-rates the onsite equipment. Having your equipment perform less well because of the altitude can massively impact the whole facility.” Understanding the factors that define a local environment can be the difference between success and disaster for a data centre, and Future-tech’s extensive experience in Kenya is a key supporting factor for IXAfrica’s success in Nairobi.
Wilman has also developed a strong collaborative relationship with Guy and Clement. “We've got over a gigawatt of design projects going through our office at the moment with different clients, which means that we're always learning new things. What is refreshing about working with Guy and Clement is that when we bring them a new idea, they listen to us,” says Wilman. “We've had a good run in Nairobi with IXAfrica built off of a long relationship, and I hope we get to continue working with them on their future projects.”
