GCN : May 2015
[BrieFing] PHOTOCREDITHERE 12 GCN MAY 2015 • GCN.COM The Commerce Department is one gi- ant step closer to its goal of unleashing its vast stores of environmental data to the public. That expanded access, however, is likely to come with a price tag attached — not for the agency but for the data’s end users. Secretary of Commerce Penny Pritzker announced a project to bring the National Oceanic and Atmospheric Administration’s vast datasets to the cloud and make them broadly avail- able. In partnership with Amazon Web Services, Google Cloud Platform, IBM, Microsoft and the Open Cloud Consortium, NOAA will seek to more effectively distribute its data to create innovative products and services. The agency gathers more than 20 terabytes of environmental data every day from a wide variety of sources, including Doppler radar systems, weather satellites, buoy networks and real-time weather stations. However, right now only a small percentage of that data is easily accessible to the public. As the demand has increased, the agency said it is imperative to find ways to effectively and efficiently distribute that data to decision-makers and industry. Accordingly, last year NOAA issued a request for information asking for sug- gestions on ways to more effectively distribute its data. The process led the agency to sign cooperative research and development agreements with its new partners. According to a 2013 McKinsey Global Institute report, open data could add more than $3 trillion in total value annually to the education, transportation, consumer products, electricity, oil and gas, health care, and consumer finance sectors worldwide. If more data could be efficiently re- leased, organizations would be able to develop new and innovative products and services to better understand the planet and keep communities resilient during extreme events, Commerce of- ficials said. The new project’s website states that the industry partners “are tasked with distributing the original data content and may recover their costs for that distribution. They may decide to provide multiple data access and distri- bution methods...and these different access methods could potentially result in different levels of cost for different offerings.” • NOAA’s no-cost plan to get more data into the cloud BY TROY K. SCHNEIDER From the labs IBM researchers have figured out a new way to squeeze even more data onto low-cost magnetic tape, a breakthrough the company said is an 88- fold improvement over the latest industry-standard magnetic tape product and a 22-fold improvement over IBM’s current enterprise-class product. The company demonstrated an areal recording density of 123 billion bits of uncompressed data per square inch, which is the equivalent of a 220 terabyte tape cartridge that could fit in the palm of your hand, IBM Research said. Although tape has traditionally been used on premise for video archives, backup files and data retention, off-premises applications are beginning to emerge in the cloud because of the storage medium’s low cost. IBM Research scientists are exploring the integration of tape technology with current cloud object storage systems such as OpenStack Swift. The new approach would enable object storage on tape and allow users to seamlessly migrate cold data to an extremely low-cost, highly durable cloud-based storage tier for backup or archival use, the company said.
