Twisting Optical Science for Bigger Optical Discs

Researchers at the Swinburne University of Technology overcome a law of optical science to develop technology boosting DVD storage capacity-- a change in writing lasers boosts DVD storage capacity from 4.7GB to up to 1 petabyte.

The technology enables "three-dimensional optical beam lithography at nine nanometres" and acts as a turnaround to Abbe's Limit, the law discovered in 1873 by Ernst Abbe.

Abbe's Limit states light beam focused by a lens cannot produce a focal spot smaller than half of the wavelength (or 500nm) for visible light. It allowed for the development of  of modern optical microscopy, but set a barrier for scientists working in the nanometer scale.

“The new technique produces a focal spot that is 1/10000 of a human hair, enabling more data to be written to disc,” Swinburne Centre for Micro-Photonics director Professor Min Gu says.

HDDs for Scale-Out Datacentres

HDDs for Scale-Out Datacentres

WD claims the WD Se HDD family is the first designed for scale-out datacentre deployments, with an enterprise platform ideal for large-scale replicated environments, mid-sized NAS and backup/archiving applications. 

“Today’s cloud datacentre installations require a cost-effective way to build large-scale storage systems, while maintaining the 24x7 reliability necessary to minimize total cost of ownership,” WD says. “WD’s utilization of vast amounts of manufacturing and engineering data has forced us-– like many other companies-– to use map-reduce methodologies to effectively analyze our data. The WD Se hard drives are used in our own big datacentre, where we have gained real-world experience with Apache Hadoop.”

The drives feature dual processors, enhanced Rotary Acceleration Feed Forward (RAFF) technology, StableTrac securing the motor shaft at both ends (reducing vibration) and a multi-axis shock sensor.  Read more...

EMC Intros ViPR Software-Defined Storage

EMC launches the ViPR "software-defined storage" platform at EMC World 2013-- a technology the company says improves customers' existing storage infrastructures based on generic server hardware. 

ViPR uses EMC software adapters to abstract existing storage arrays into a single pool of virtual storage, creating a "plug and play" environment. It manages both infrastructure (in the so-called "Control Plane") and data stored within ("Data Plane), allowing customers to either use both or manage storage arrays wholly through the Control Plane. 

Admins can partition storage pools into various storage arrays, managing them by policy-- a process similar to partitioning servers into multiple virtual machines VMware vCentre. Applications can take advantage of multiple types of storage with automated management, provisioning and other capabilities.   Read more...

Solid State is a Solid Opportunity says IDC

Solid State is a Solid Opportunity says IDC

Solid State Storage (SSS) represents a golden near future opportunity IDC reports-- the analyst forecasts the global all-SSS array market will reach $1.2 billion in revenues by 2015. 

The technology is becoming increasingly ideal for enterprise customers (particularly for heavy duty cloud, virtualisation, big data and analysis applications) since SSDs take less physical footprint while delivering more IOPS over a similar environment than HDDs. 

Falling SSD prices per GB also make SSS more appealing to a wider storage market, while price performance metrics (such $/IOPS or $/workload) are starting to hold more weight.  Read more...

IBM Invests in Flash

IBM reveals a "strategic initiative" worth $1 billion to drive enterprise adoption of flash technology optimised for social media, mobility and big data workloads. 

The investment includes the 2012 acquisition (for an unspecified sum) of shared rackmount and server-based PCIe flash storage developer Texas Memory Systems (TMS) and 12 Centres of Competency set to open by end 2013. 

The UK, France and Germany will host such centres, which should allow customers to run test out IBM flash solutions with real-world data.  

“The economics and performance of flash are at a point where the technology can have a revolutionary impact on enterprises, especially for transaction-intensive applications,” IBM says. “The confluence of Big Data, social, mobile and cloud technologies is creating an environment in the enterprise that demands faster, more efficient, access to business insights, and flash can provide that access quickly.”   Read more...
