Energy-efficient datacenters

by Massoud Pedram - IEEE Trans. on CAD , 2012
"... Abstract—Pervasive use of cloud computing and the resulting rise in the number of datacenters and hosting centers (which provide platform or software services to clients who do not have the means to set up and operate their own compute facilities) have brought forth many concerns including the elect ..."

cost-optimal manner so as to meet different performance criteria such as throughput or response time has become a critical challenge. The goal of this paper is to provide an introduction to resource provisioning and power/thermal management problems in datacenters and to review strategies that maximize

Benefits and Limitations of Tapping into Stored Energy For Datacenters

by Sriram Govindan, Bhuvan Urgaonkar, et al. , 2011
"... Datacenter power consumption has a significant impact on both its recurring electricity bill (Op-ex) and one-time construction costs (Cap-ex). Existing work optimizing these costs has relied primarily on throttling devices or workload shaping, both with performance degrading implications. In this p ..."

Jetway: Minimizing Costs on Inter-Datacenter Video Traffic

by Yuan Feng, Baochun Li, Bo Li
"... It is typical for video streaming service providers (such as NetFlix) to rely on services from cloud providers (such as Amazon), in order to build a scalable video streaming platform with high availability. The trend is largely driven by the fact that cloud providers deploy a number of datacenters i ..."
Abstract - Add to MetaCart
video traffic incurs substantial operational costs to a cloud provider. In this paper, we argue that costs incurred by such inter-datacenter video traffic can be reduced or even minimized by carefully choosing paths, and by assigning flow rates on each inter-datacenter link along every path. We present

CoolProvision: Underprovisioning Datacenter Cooling

by Ioannis Manousakis, Sriram Sankarδ
"... Cloud providers have made significant strides in reducing the cooling capital and operational costs of their datacenters, for example, by leveraging outside air (“free”) cooling where possible. Despite these advances, cooling costs still repre-sent a significant expense mainly because cloud provider ..."

Software Architecture for Dynamic Thermal Management in Datacenters

by Tridib Mukherjee, Qinghui Tang, Corbett Ziesman - In Proceedings of COMSWARE , 2007
"... Abstract — Minimizing the energy cost and improving thermal performance of power-limited datacenters, deploying large computing clusters, are the key issues towards optimizing their computing resources and maximally exploiting the computation capabilities. In this paper, we develop a unique merger b ..."

Improving Per-Node Efficiency in the Datacenter with New OS Abstractions

by Barret Rhoden, Kevin Klues, David Zhu, Eric Brewer
"... We believe datacenters can benefit from more focus on per-node efficiency, performance, and predictability, versus the more common focus so far on scalability to a large number of nodes. Improving per-node efficiency decreases costs and fault recovery because fewer nodes are required for the same am ..."

SmartDPSS: Cost-Minimizing Multi-source Power Supply for Datacenters with Arbitrary Demand

by Wei Deng, Fangming Liu, Hai Jin, Chuan Wu , 2012
"... Abstract—To tackle soaring power costs, significant carbon emission and unexpected power outage, Cloud Service Providers (CSPs) typically equip their Datacenters with a Power Supply System (DPSS) nurtured by multiple sources: (1) smart grid with time-varying electricity prices, (2) uninterrupted pow ..."

the grid markets, for minimum operational cost. We thoroughly analyze the performance of our online control algorithm with rigorous theoretical analysis. We also demonstrate its optimality in terms of operational cost, demand service delay, datacenter availability, system robustness and scalability, using

MultiGreen: CostMinimizing Multi-source Datacenter Power Supply with Online Control

by Wei Deng, Fangming Liu, Hai Jin, Chuan Wu, Xue Liu - in Proc. of ACM e-Energy , 2013
"... Faced by soaring power cost, large footprint of carbon emis-sion and unpredictable power outage, more and more mod-ern Cloud Service Providers (CSPs) begin to mitigate these challenges by equipping their Datacenter Power Supply Sys-tem (DPSS) with multiple sources: (1) smart grid with time-varying e ..."

Our detailed analysis and trace-driven sim-ulations based on one-month real-world data have demon-strated the optimality (in terms of the tradeoff between min-imization of DPSS operational cost and satisfaction of data-center availability) and stability (performance guarantee

Managing inter-datacenter (DC) connectivity to transport increasing amounts of data and optimize DC performance and costs becomes a challenge not only for DC operators but also for network operators. Current inter-DC connections are configured as static big fat pipes, resulting in large bitrate over ..."
