Improved Data Center Energy Efficiency and Availability with Multilayer Node Event Processing

Modeling and Availability Analysis of Internet Data Center with various Maintenance Policies

In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...

Eco Computing: Improving Data Center Energy Efficiency

Optical Data Center Networks: Architecture, Performance, and Energy Efficiency

In a data center, servers communicate with each other to store and handle a large amount of data. Thus, the network within a data center affects the performance of the data center; the lack of bandwidth between servers increases the time to obtain the required data from the other servers. The energy consumption is also one of the important problems in a data center. The energy consumed by the d...

Models and Control Strategies for Data Center Energy Efficiency

As the foundation of the nation’s information infrastructure, data centers have been growing rapidly in both number and capacity to meet the increasing demands for highlyresponsive computing and massive storage. Data center energy consumption doubled from 2000 to 2006, reaching a value of 60 TWh/year (Tera Watt hour / year). Coupled with increasing power and cooling demands imposed by the Moore...

Node and Sink Mobility Supported Routing Protocol in Wireless Sensor Network with Improved Energy Efficiency

The proposed routing protocol for Wireless Sensor Network is hierarchical and cluster based. The protocol supports mobility in the Sensor Nodes as well as in the Sink. The entire protocol is described in terms of two phases namely Setup Phase and Data Forwarding Phase. After deployment of the Sensor Nodes entire sensor field in divided into some logical clusters and each cluster contains Sensor...
