In this paper, we investigate power and QoS (Quality of Service) performance characteristics of virtualized servers with virtual machine technology. Currently, one of the critical problems at data centers with many thousands of servers is the increased power consumption. Virtual machines (VMs) are often used for Internet services for efficient server management and provisioning. While we expect that...
We propose a service rate matching optical receiver module for PS-based WDM PON systems that offer maximum bit rates of over 40 Gb/s. Proposed module provides line rate flexibility with low power consumption.
In this paper, we propose a scheme based on server node state control, including stand-by/wake-up and processor power control, to achieve aggressive power education while satisfying Quality of Service (QoS). Decreasing power consumption on Web servers is currently a challenging new problem to be solved in a data center or warehouse. Although Web servers are configured to have maximum performance,...
