Behind the Science is an occasional series of blogs focusing on the people advancing science and technology.

George and Marlene Bachand, a married couple working at Sandia National Laboratories, have partnered on more science projects than they can recall.

Organizations constantly are seeking new ways to address workload-specific storage demands in terms of performance and capacity while also meeting service-level agreements, response-time objectives and recovery-point objectives.

Many information technology operations are inspired by successful hyperscale organizations such as Facebook, Google and Amazon. However, most enterprises lack the scale and substantial development and operations commitment necessary to deploy software-defined storage infrastructure in the same ways. Hyperscale economics also typically don’t work out at smaller scale, resulting in poor utilization or unacceptable reliability issues.

World Wide Technology Inc., Maryland Heights, Maryland, was awarded a $7,980,851 firm-fixed-price contract for purchase of data storage hardware, software, maintenance and professional implementation services to replace the obsolete data storage items at all affected Army Corps of Engineers locations. Bids were solicited via the Internet, with six received. Work will be performed in Maryland Heights, with an estimated completion date of March 31, 2017. Fiscal 2016 other funds in the amount of $7,980,851 were obligated at the time of the award. Army Corps of Engineers, Huntsville, Alabama, is the contracting activity (W52P1J-16-D-0016).

Federal agencies use risky network setups to support mission- and business-critical systems, particularly in light of global IP data center traffic growing 23 percent a year and taxing networks to deliver data reliably and efficiently, according to a Market Connections survey released today. The study was commissioned by the technology company Brocade. 

Researchers polled 200 information technology decision makers across 57 federal agencies and noted that nearly half of mission-critical workloads, and more than one third of business-critical workloads, are accessed through shared IP storage networks, which were not designed to support the increasing workloads that compromise performance, reliability and security.

Laserdisc technology offers greater capacity and enhanced backward compatibility.

The increasingly heavy flow of data within organizational networks is driving the search for better methods to store actively used information and archives. Advances in optical-disc technology are producing greater versatility in multimedia hardware and software. As a result, consumers will soon achieve increased systems interoperability through a more refined focus on equipment compatibility.

Information storage dilemma draws attention of planners.

Although it is not as glamorous as smart weapons or miniaturized sensors, data storage is emerging as an increasingly important issue in the U.S. military. As the services continue to move toward a networked force, U.S. Defense Department leaders are beginning to pay close attention to how and where to store the data and images that sophisticated technologies are gathering in enormous quantities. After all, it not only has to be kept somewhere, but it also must be readily accessible to be valuable.

Researchers explore alternative recording systems using light and microscopic dots and dashes.

From clay tablets to magnetic tape, civilizations have found ways to store important information; however, the silicon revolution has led to an overabundance of data. While existing electronic media have kept pace with this demand, new technologies could offer massive storage coupled with fast retrieval.

Scientists are exploring new systems that could become commercially available in the coming decades while continuing work on improving the capabilities of existing media. Some of these techniques, such as light-based memory, may open new paths for high-speed computing, experts say.
