Internet-based applications and their resulting multitier distributed architectures have changed the focus of design for large-scale Internet computing. server execute in a horizontally scalable topology across hundreds or thousands commodity servers data centers. Increasing scale power density significantly impacts center's thermal properties. Effective management is essential to robustness mission-critical applications. service can address multisystem resource as well within
Thermal challenges in next-generation electronic systems, as identified through panel presentations and ensuing discussions at the workshop, Challenges Next Generation Electronic Systems, held Santa Fe, NM, January 7-10, 2007, are summarized this paper. Diverse topics covered, including electrothermal multiphysics codesign of electronics, new nanostructured materials, high heat flux thermal management, site-specific design data centers, for military, automotive, harsh environment progress...
This paper seeks to understand and design next-generation servers for emerging "warehouse-computing" environments. We make two key contributions. First, we put together a detailed evaluation infrastructure including new benchmark suite warehouse-computing workloads, performance, cost, power models, quantitatively characterize bottlenecks. Second, study solution that incorporates volume non-server-class components in novel packaging solutions, with memory sharing flash-based disk caching. Our...
Large-scale data centers (~20,000m 2 ) will be the major energy consumers of next generation. The trend towards deployment computer systems in large numbers, very dense configurations racks a center, has resulted high power densities at room level. Due to heat loads (~3MWs) an interconnected environment, center design based on simple balance with zones, is inadequate. Energy consumption can severely increased by inadequate air handling and rack layouts that allow hot cold streams mix. In...
The mobility/cloud ecosystem aims to deliver infrastructure, platforms, and software as a service, enabling more people benefit from ubiquitous information access. culmination of 10 years' research converges on-demand applications with the infrastructure—servers, storage, networks, client devices—to support cloud computing.
Increases in server power dissipation time placed significant pressure on traditional data center thermal management systems. Traditional systems utilize computer room air conditioning (CRAC) units to pressurize a raised floor plenum with cool that is passed equipment racks via ventilation tiles distributed throughout the floor. Temperature typically controlled at hot return of CRAC away from racks. Due primarily lack environmental sensing, these are often operated conservatively resulting...

The Internet of Things (IoT) refers to a pervasive presence interconnected and uniquely identifiable physical devices. These devices' goal is gather data drive actions in order improve productivity, ultimately reduce or eliminate reliance on human intervention for acquisition, interpretation, use. proliferation these connected low-power devices will result explosion that significantly increase transmission costs with respect energy consumption latency. Edge computing reduces by performing...

Abstract Power dissipation within computer rooms or data centers has been steadily increasing over the past decade. With spread of CMOS technology into microprocessors and memory in 1980s 1990s, water-cooled mainframe systems were largely supplanted by lower power air-cooled systems. These typically stacked 2-m-high racks for efficient use expensive center floor space. Data environmental cooling infrastructures correspondingly evolved designs that recirculate hot exhaust air from...
The modeling of recirculation patterns in air-cooled data centers is interest to ensure adequate thermal management computer racks at increased heat densities. Most metrics that describe are based exclusively on temperature inside the center, and therefore fail provide information regarding energy efficiency infrastructure. This paper addresses this limitation through an exergy analysis center system. approach recognizes mixing hot cold streams airspace irreversible process must lead a loss...
