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.
Virtualization can deliver dramatic benefits for data centers, but it can also stress the underlying support infrastructure. Power and cooling systems—which may have been quite sufficient for pre-virtualization needs—could easily become inadequate when data center performance patterns are radically altered. This paper describes some of power challenges related to virtualization—and the readily available technologies to address them.
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.
Through a combination of integrated hardware and software components, ARM TrustZone* technology provides the basis for a highly-protected system architecture targeted specifically at securing consumer products such as mobile phones, PDAs, set-top boxes or other systems running open Operating Systems (OS), such as Symbian OS, Linux and Windows CE.
A number of options are available to facilities professionals looking to improve cooling efficiency and reduce resources consumed by their data centers. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data centers.
Embedded system designers have a variety of code execution methods to choose from: eXecute-In-Place (XIP), Fully Shadowed and Demand Paging. Using the best method is the key for a cost-effective solution. Each method has different implications in terms of RAM and Flash usage which directly affect the cost of the system.
This white paper examines the various current source topologies that can be implemented to design drivers for LED-backlit LCDs, the advantages and disadvantages of each, and how they can be used in combination with new current source designs to develop new multiple-string LED driver topologies.
The white paper discusses the need of containing and suppressing the EMI potential of electronic systems found on automobiles through EMI shielding and ferrite solutions.
To meet the exacting demands of multiple IT environments, including that of a virtual operating environment, a Nexsan SASBeast provides IT with a storage resource fully optimized for reliability and performance. Each physical unit features design innovations to extend the lifespan of installed disk drives.
