Many of the mysteries of equipment failure, downtime, software and data corruption, are the result of a problematic supply of power. There is also a common problem with describing power problems in a standard way. This white paper will describe the most common types of power disturbances, what can cause them, what they can do to your critical equipment, and how to safeguard your equipment, using the IEEE standards for describing power quality problems.

This white paper describes how HP LeftHand SANs can help you deploy VMware Infrastructure 3 (VI3) software more effectively through volume snapshots, SmartClone volumes, volume migration, and high-availability features. With HP LeftHand SAN and VI3, organizations can reclaim valuable data center space and reduce their power and cooling requirements.

Data centre managers might be feeling upset right now. After years of running the most powerful and most organised data centres they possibly could, someone has moved the goalposts. Efficiency was always important, but now it has jumped up the list of factors against which IT performance is measured. And efficiency has changed its meaning. In the past, it was enough to deliver services on-time and to budget, make sure there was enough capacity to meet future demands, run a secure site and have back-up plans ready for any emergency.

"As the number of enhancements to various Hardware Description Languages (HDLs) has increased over the past year, so too has the complexity of determining which language is best for a particular design. Many designers and organizations are contemplating whether they should switch from one HDL to another. This paper compares the technical characteristics of three, general-purpose HDLs.

Getting a handle on power means installing tools that help you not only measure consumption but also right-size your electrical infrastructure and increase uptime.

The Business Ready Configurations for Dell PowerEdge blade servers, Dell EqualLogic SAN, and VMware Infrastructure provides a detailed reference architecture for deploying and using VMware virtualization on Dell blades and iSCSI storage environments. The Dell PowerEdge M1000e supports the recently announced 11th generation Dell PowerEdge M610 and M710 blade servers based on the new Intel Xeon processors.

A powerful signal integrity analysis tool must be flexibility, easy to use and integrated into an existing EDA framework and design flow. In addition, it is important for the tool to be accurate enough. This report reviews a validation study for the Mentor Graphics HyperLynx 8.0 PI tool to establish confidence in using it for power integrity analysis.

For advanced signaling over high-loss channels, designs today are using equalization and several new measurement methods to evaluate the performance of the link. Both simulation and measurement tools support equalization and the new measurement methods, but correlation of results throughout the design flow is unclear. In this paper a high performance equalizing serial data link is measured and the performance is compared to that predicted by simulation. Then, the differences between simulation and measurements are discussed as well as methods to correlate the two.

High Density Interconnect (HDI) is being used more often to meet the growing need for more complex designs in smaller form factors. Beyond some of the more obvious electrical effects of using smaller vias, there is also an impact to the power integrity of a board using HDI. This includes different effects of mounted inductances of decoupling capacitors, changes in plane performance due to reduction in perforation from chip pinouts, and the inherent plane-capacitance changes from using dielectrics of various thicknesses. This paper will examine and quantify these effects, using numerous design examples, including a large conventional through-hole design board that was reduced using HDI.

The success of any consumer electronic device depends to a large extent on the appeal of the user interface (UI) and how easy the device is to use. Studies show that good cosmetic design can encourage users to explore the full range of features and often engenders the perception that a product is easier to use. So if the benefits of a great looking, easy-to-use UI are so clear, why are so many products still falling short of customer expectations? The solution lies in taking a fresh new approach a consumer electronic device UI plays. By identifying common UI functionality and implementing it in a reusable and customizable way, we can make it far easier for embedded engineers to deliver visually engaging and easy-to-use consumer electronic products.

Moving to C++ presents opportunities for higher programmer productivity. The requirements of embedded systems, however, demand that the adoption of C++ be carefully measured for the performance impact of run-time costs present in C++, but not in C. This talk suggests strategies for developers who are starting their acquaintance with C++.

Data centers are large, important investments that when properly designed, built and operated, are an integral part of the business strategy driving the success of any enterprise, yet the central focus of organizations is often the acquisition and deployment of the IT architecture equipment and systems, with little thought given to the structure and space in which it is to be housed, serviced and maintained. This invariably leads to facility infrastructure problems, such as thermal hot spots, lack of UPS, rack power, lack of redundancy, system overloading and other issues that threaten or prevent the realization of the return on the investment in the IT systems.

Data centers are large, important investments that, when properly designed, built, and operated, are an integral part of the business strategy driving the success of any enterprise. Yet the central focus of organizations is often the acquisition and deployment of the IT architecture equipment and systems with little thought given to the structure and space in which it is to be housed, serviced, and maintained. This invariably leads to facility infrastructure problems such as thermal “hot spots”, lack of UPS (uninterruptible power supply) rack power, lack of redundancy, system overloading and other issues that threaten or prevent the realization of the return on the investment in the IT systems.

Identify a strategic entry point for data center transformation to achieve facilities that are scalable, modular, energy-efficient, and continuously available.

Dell servers have been optimized to help provide strong support for the latest ESX release, VMware ESX 3.5 Update 2, including enhanced performance for virtualized environments based on support for six-core Intel Xeon processors. Organizations that do not approach server virtualization with a clear plan risk developing a chaotic, inflexible infrastructure that wastes energy and resources.

Comprehensive guidelines for cost-effective die casting production. Written for OEM product designers and engineers to aid in optimizing their part designs and specifications for custom production in Aluminum, Magnesium, and Zinc die casting alloys.

Voice Over IP (VoIP) deployments can cause unexpected or unplanned power and cooling requirements in wiring closets and wiring rooms. Most wiring closets do not have uninterruptible power available, and they do not provide the ventilation or cooling required to prevent equipment overheating. Understanding the unique cooling and powering needs of VoIP equipment allows planning for a successful and cost effective VoIP deployment. This paper explains how to plan for VoIP power and cooling needs, and describes simple, fast, reliable, and cost effective strategies for upgrading old facilities and building new facilities.

Using digital control in power supplies is considerably more flexible than analog control in its ability to adapt to changes and digital control inside the power supply results in advantages to the system application such as improved efficiency, fewer external components and reduced overall cost.

“Medical grade DC/DC converters” is an often used, but more often abused, description of a class of converters that are increasingly in demand. What are actually the particular requirements that medical applications place on DC/DC converters?

Power distribution units (PDUs) are vital to the management of power to IT arrays and have evolved from a simple panel of switches and outlets to designs that can now be considered "intelligent" through the inclusion of internal processing capabilities.

Uninterruptible Power Solutions are often solved at the facility level with unnecessarily large, inefficient, expensive and complex AC UPS systems. While this provides an easy demarcation line between the facility and end equipment, with each focusing on a different part of the problem, it also results in overall operating efficiency and total cost of ownership being difficult to ascertain and optimize.
