TORONTO – Statistically, flying is the safest way to travel. We don’t worry about airplanes dropping from the sky. But drones are another thing altogether.
If a drone runs into mechanical problems, there’s no Chesley “Sully” Sullenberger to land it on the Hudson River. To keep unmanned aerial vehicles (UAVs) from landing on our heads, NASA is trying to make them smarter.
Dubbed Safe2Ditch, the technology is aimed at allowing drones to continuously run self-diagnostics during flight to anticipate problems. If something goes wrong, the system could make changes to how the drone is flying and estimate how much longer it could stay in the air.
Since a drone with mechanical problems would need to set down quickly, Safe2Ditch would immediately begin to search its database for safe landing locations and autonomously land at the closest spot. Safe landing options would include fields, parking lots or parks, said Lou Glaab, assistant branch head for the Aeronautics Systems Engineering Branch at the NASA Langley Research Center. Worst case scenario, a drone might have to land in a dense forest to avoid people, but the goal is to keep avoid damaging the drone in an emergency landing.

TORONTO – As Ethernet speeds get faster, Rambus is looking to make sure memory and interfaces can keep up with the recent launch 56G SerDes PHY.
The analog-to-digital converter (ADC) and (DSP) architecture of the 56G SerDes PHY is designed meet the long-reach backplane requirements for the industry transition to 400 GB Ethernet applications, said Mohit Gupta, senior director of product marketing at Rambus. This means it can support scaling to speeds as fast as 112G, which are required in the networking and enterprise segments, such as enterprise server racks that are moving from 100G to 400G.
“Ethernet is moving faster than ever,” Gupta said. “The pace has picked up substantially due to big data, the Internet of Things (IoT) and other trends putting high demands on communication channels. There is already a forum for 112G SerDes speed which will drive the 800G standard.”
One clear usage case, said Gupta, is data center deployment by the “big four” — Facebook, Microsoft, Amazon and Google.

Hosted data centers have become a common avenue for enterprises to access and deliver IT services, but they’re also a hit with cyber criminals.
According to a recent report by ThreatMatrix, there is a correlation between top U.S. cities for online fraud and those that are home to hosted data centers, with Tampa, Fla. topping the list, followed by New York. Major U.S. cities rounding out the top 10 included Los Angeles, Atlanta and Chicago. [Read the full story on IT World Canada]
The NVM Express Work Group has decided to incorporate itself to further the NVM Express (NVMe) specification for accessing solid-state disks (SSDs) on a PCI Express (PCIe) bus. NVMe is a standardized register interface, command, and feature set for PCIe-based storage technologies such as SSDs, designed specifically for non-volatile memory. It is optimized for high performance and low latency, scaling from client to enterprise segments. Read Full Article.
As DDR4 awaits widespread adoption and new technologies such as hybrid memory cube continue to be fleshed out, there remains opportunity to improve on DDR3’s performance, and more importantly, its design and manufacturing. Last week, Samsung announced it was mass producing what the company said is the most advanced 4Gb DDR3 memory based on a new 20 nanometer process technology using immersion ArF lithography.

While businesses turn to proven systems for their high-performance computing needs, research institutions are more willing to experiment and take a chance on the latest and greatest to solve complex problems. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is the perfect example: It recently selected SGI’s large-scale shared memory system, the UV 2000, for installation at its Earth Simulator supercomputer center.

The Hybrid Memory Cube Consortium (HMCC) is making steady progress on bringing one of the most discussed heirs to DDR4 closer to reality by releasing an update to the HMC specification late last month. The first draft of the second-generation specification supports increased data rates that advance short-reach (SR) performance from 10 Gbit/s, 12.5 Gbit/s, and 15 Gbit/s, up to 30 Gbit/s.

Startup A3Cube recently announced a new network interface card, dubbed RONNIEE Express, designed to eliminate the I/O performance gap between CPU power and data access performance for datacenters, big data, and high-performance computing applications. The company said that by turning PCI Express into an intelligent network fabric, it can exceed existing networking technologies such as Ethernet, InfiniBand, and Fibre Channel, and improve memory latencies.

There are a number of next generation memory technologies on the horizon that hold great promise to meet the evolving needs of consumer devices and enterprise storage systems and applications. Some have been in development for a number of years, and are close to a critical turning point that will see them widely adopted. Here’s a few that merit watching in the next year, including several DRAM alternatives. Read my full article on EE Times.
NEWARK, Calif. – The higher costs of SSDs (relative to spinning disks) and their lifespan limitations generally keep enterprises from fully embracing them for storage. The ongoing challenge is how to optimize them to get the best bang for the buck, while also addressing the endurance problem. Read the full article on EE Times.
