The PowerEdge SC1435 is a two-socket, rack-dense server optimized forhigh-performance compute clusters, distributed Web serving and small- tomedium-sized businesses that require leading price-performance ratio and energyconservation features. The AMD Opteron processor-based PowerEdge SC1435 candeliver performance gains of up to 128 percent(3) and performance-per-wattimprovements of up to 138 percent(4).

"The PowerEdge 6950 and PowerEdge SC1435 continue Dell's unwavering commitmentto meet customer needs and lead the industry in price-performance andperformance per watt," said Brad Anderson, senior vice president, Dell ProductGroup. "These servers - combined with the integration of Dell OpenManage withOracle applications to simplify the deployment, management and monitoring ofOracle applications - deliver the solutions our customers need to reducecomplexity in enterprise environments."

Marty Seyer, senior vice president of AMD's Commercial Segment, noted Dell andAMD's vision to deliver uncompromising performance-per-watt choices and completesolutions to Dell enterprise customers.

"AMD and Dell share a commitment to deliver system-wide innovation where itmatters most to customers," said Seyer. "By combining Dell's world-class productdesign, service and support with the performance-per-watt benefits of AMDOpteron processors and open innovation platform enabled by the AMD Torrenzainitiative, customers have the right tools for addressing specific workloadneeds and applications while reducing total cost of ownership."

Grid Management: Simplified

Dell and Oracle have integrated Dell OpenManage and Oracle Enterprise Manager tooffer an industry-first solution for simplified management of the Oracleapplication infrastructure. The integration of these standards-based toolsenables customers to natively manage Dell PowerEdge servers within a singlemanagement console familiar to Oracle database administrators.

By continuing its commitment to integrate its OpenManage product family withpartner solutions, Dell is delivering standards-based, enhanced management forcustomers. This enables fast issue isolation and improved availability betweenapplication and hardware, helps minimize training and use of multiple tools andleverages existing IT investments for customers.

The integration of Dell OpenManage and Oracle Enterprise Manager includessupport for lifecycle management of Dell PowerEdge servers with features suchas:

System discovery, reporting and configurationManaging server hardware healthCross-platform system event notificationEvent-driven policy executionDell PowerEdge - Excellence in Performance and Performance per Watt

The new servers complement Dell's ninth-generation PowerEdge serversintroduced earlier this year, delivering the most comprehensive technology anddesign enhancements ever to the widely installed product line. Enhancementsinclude:

Industry-first programmable LCD that enables quick and easy visualdiagnosis of server faultsIndividually labeled hard drives that provide quick identification of thetechnology, capacity and speedStandardized color coding and cabling that help make PowerEdge serverseasier to manage and service today and with future generationsDraw-latch design for tool-less access to server componentsImageWatch(TM), a Dell service that helps customers proactively manage thenumber of changes to system images, available in a block-release formatfurther helping to reduce the number of image changes a customer has tomanage.SAS (Serial Attached SCSI) hard drives for fast, reliable datatransmission and minimized thermal outputTCP/IP Offload Engine, which helps reduce traffic on a host processor toenhance system performanceEnhanced virtualization technology for improved performance, managementand utilization in virtualized workloads such as VMware ESX, Microsoft VirtualServer or XenPCI-Express I/O, which delivers high-performance Ethernet, RAID,InfiniBand and Fibre Channel interconnect while providing investmentprotection for future technologies Dell Platinum Plus Delivers Complete Enterprise Solutions, EnablesExtended Uptime

Customers buying Dell's newest PowerEdge servers can also benefit fromPlatinum Plus Enterprise Support, Dell's highest level of enterprise support.Platinum Plus provides reliability and global consistency for customers withbusiness-critical needs. It includes the industry's first Operations PerformanceBenchmarking feature, a patent-pending methodology that allows customers toroutinely compare critical IT performance metrics to historical results andsimilarly configured environments.

Cyclogyro Flying Robot Improves its Angles of Attack

Enlarge

(PhysOrg.com) -- In the past few decades, researchers have been investigating a variety of flying machines. Most studies have focused on improving the flying performance of standard flying mechanisms, rather than developing innovative flying mechanisms.

But one intriguing flying mechanism that has received relatively little attention is a horizontal-axis rotorcraft - or "cyclogyro" craft. First proposed in the 1930s, a cyclogyro is a unique mechanism of generating lift forces, being propelled by horizontal rotating wings. Unfortunately, the few prototypes that were built at the time were unsuccessful at flying.

The essential flying principle of the cyclogyro rotorcraft is that, as the wings rotate, their angle of attack must be altered so that the wings can lift and thrust at the appropriate times in the cycle. Designing such variable wings that can alter the angles of attack has proven difficult.

But recently, a team of engineers consisting of Naohiro Hara, Kazuo Tanaka, and Hiroshi Ohtake from the University of Electro-Communications in Japan, and Hua O. Wang of Boston University in the US, have developed a cyclogyro flying robot with a new kind of variable wing mechanism. The mechanism is based on a pantograph, which is a mechanical linkage that was originally developed in the 17th century as a drafting tool for copying and scaling line drawings.

IEEE Transactions on Robotics. The mechanism is an extension of two of the authors' earlier prototype designed in 2006, which demonstrated that a cyclogyro-based flying robot could generate enough lift force to fly and carry a very small (10 g) payload. With the new mechanism, the researchers hoped to improve the efficiency. Through simulations and experiments, they focused on demonstrating the possibility of a flying robot with a pantograph-based mechanism.

The engineers explained that, in the downstroke motion, the new mechanism can generate heavy lift forces in the upward direction by expanding the wings with larger angles of attack. Conversely, in the upstroke motion, the mechanism can reduce anti-lift forces in the downward direction by contracting the wings with smaller angles of attack. Due to this folding up motion of the wings, which creates a larger wing area in a small space, the rotorcraft can get a larger lift force compared with the authors' previous strategy.

The simulations and experiments (in which the rotorcraft was tethered for stability) showed that the robot could generate a lift force exceeding its own weight. Not only could this force allow the robot to fly, it means the robot could carry a significant payload (155 g). Accounting for the robot's four rotors, the engineers hope that it may be possible to fly the robot with a battery, some sensors, and even a control board (currently, the robot receives power from an external supply).

In the future, the engineers plan to develop a detailed aerodynamic analysis of the wing motion. Eventually, they hope to develop a full-body flying robot with the optimal parameters, including four sets of pantograph-based variable wings and a stabilizing controller. With its ability to rise, hover, and go backward, a cyclogyro flying robot could one day operate as a highly maneuverable micro air vehicle.
