Power Usage Effectiveness (PUE) is a metric used to measure data center infrastructure efficiency. While PUE provides a simple and useful ratio, it does not capture many important factors like resilience, load diversity, and server utilization. Additional metrics are needed to fully understand efficiency opportunities and benchmark the performance of the IT equipment itself. PUE should be considered as just one aspect of data center efficiency measurement and management.
The document discusses the TPC-Energy Specification, which was developed to standardize the measurement of energy consumption for IT systems. It aims to provide metrics for price, performance, and power consumption to help customers make more informed purchasing decisions. The specification supplements existing TPC benchmarks by reporting the energy used when running standard workload tests, as well as the energy used by system subcomponents. It also outlines requirements for the system configuration and testing environment to reflect real-world usage. The first results published under this specification included energy consumption figures for several HP server models running TPC workload benchmarks.

EPRI Activities for Energy Efficiency in Data Centers & Telecom Central Offic...Burton Lee
The document discusses EPRI's activities to improve energy efficiency in data centers and telecom central offices. It notes that while data centers and central offices share similarities like installing large amounts of IT equipment, they differ in aspects like operating voltages and equipment certifications. The document outlines EPRI's testing of more efficient power supplies and demonstration of air flow management software that saved 23% of energy in a data center. It also shows a comparison of 208 VAC and 380 VDC systems.
The document discusses the utility and limitations of PUE (Power Usage Effectiveness) as a metric for datacenter efficiency. While PUE is a widely used high-level metric, it does not provide enough information on its own to optimize efficiency. To enable effective efficiency actions, more detailed energy monitoring data is needed, including power consumption at the individual IT device level trended over time. Gathering additional operational data beyond just PUE can provide insights to reduce energy waste throughout the entire datacenter system.
The document discusses real-time monitoring tools for data centers and their value over traditional point-in-time measurements. It highlights results from surveys showing energy efficiency and monitoring are top concerns. Real-time tools provide continuous monitoring of metrics like temperature, humidity, power usage and IT load to ensure optimal performance, efficiency and availability. The presentation concludes with a live demo and emphasizes that the future of data center monitoring involves non-invasive, rack-level tools for ongoing assessment and improvement.

Sustainable IT for Energy Management: Approaches, Challenges, and TrendsEdward Curry
An invited talk to the Galway-Mayo Institute of Technology on the current state of the art in Sustainable IT for energy management, the challenges, and the emerging trends.
This document discusses the utility and limitations of PUE (Power Usage Effectiveness) as a data center efficiency metric. While PUE is a useful high-level metric, it does not provide enough detail to optimize efficiency. PUE only measures the ratio of total facility power to IT equipment power, but does not account for factors like server utilization, resilience, or diversity of the IT load. The document argues that more detailed energy monitoring data is needed at the server, rack, and application level over time to properly evaluate efficiency and enable tangible efficiency actions.

Improved efficiency & reliability for servers using immersion cooling technologyASQ Reliability Division
Data centers have traditionally been high power consumers. In a “green” data center, instead of being air-cooled, servers are submerged in a non-toxic dielectric fluid that is 1200 times more effective at whisking away heat. By using state of the art liquid immersion cooling, the power required to run each server is reduced by up to 50% and the power required to cool a server room is reduced by up to 90%. For perspective, power costs represent from 25-40% of monthly data center operating expenses. Any energy expended other than that to drive the IT Load contributes to inefficiency.
Immersion technology largely eliminates the temperature swings that can lead to processor and electronics failures. Micro-arcing is also eliminated as a concern since there is no dust or oxygen in the oil environment. There is also a potential to further mitigate against tin whisker failures since the bath could break whiskers or coat them to prevent shorts. Risk of failure due to airborne contaminants like dust, debris, and corrosive gases is eliminated. The improved heat dissipation of immersion technology also allows comfortable operation of cutting-edge, higher powered servers. So, an immersion cooled data center draws much less power and consequently has a smaller carbon footprint than conventional data centers.
Preparing a server for immersion is fairly straightforward. Simply remove the fans, replace any thermal paste with foil, and encapsulate the boot disk or use a solid state drive ( SSD). Working on a server is equally straightforward. Pull the server out of the fluid and wait for it to drain. Keep a nearby paper towel for any drips.
The document discusses LISP (Locator/ID Separation Protocol), which was developed by Cisco to address scalability issues facing the Internet. LISP solves these issues by separating a host's identifier (EID) from its locator (RLOC) using an encapsulation scheme and mapping system. This allows routing scalability by removing most host routes from the global routing system and storing them in a distributed database. The document outlines LISP's control and data plane operations, use cases, and Cisco's involvement in developing and standardizing the protocol.
This document discusses the transition to IP/MPLS in mobile backhaul networks.

The document proposes a solution for scaling LDP-based pseudowire (PW) services across multiple regions. It uses LDP signaling for setting up intra-region PWs and BGP for inter-region stitching and routing. The solution allows PW services to extend across autonomous systems and areas without requiring protocols like BGP on terminating provider edges (T-PEs). Provisioning and signaling are simplified through the use of attachment identifiers and route targets. Existing T-PE capabilities are largely reused through minor extensions to FEC-128/129 signaling over LDP. BGP routing between switching provider edges (S-PEs) avoids a full mesh of LDP sessions to improve scaling as the number of T-
This document discusses using label switched multicast (LSM) for optimized video delivery over MPLS networks. It covers market trends in video, types of video, video delivery architectures, and an overview of label switched multicast using RSVP-TE and mLDP signaling. Examples applications of LSM for video contribution, primary distribution, and enterprise distribution are provided. The document concludes that MPLS networks are increasingly being used for different types of video delivery and that LSM can optimize this delivery through applications tailored to specific video use cases and requirements.
This document discusses automation of next generation networks (NGNs) to deliver multicast services. It covers planning issues for deploying multicast across inter-domain networks, including using path computation elements (PCEs) and hierarchical PCEs. Extensions to RSVP signaling are presented as a solution for point-to-multipoint transport across domains. The use of PCEs can offload complex path computations and consider constraints to efficiently deliver services using multicast trees.

1) The document proposes an adaptive-mesh grid network of 5 data centers powered by solar, wind, and geothermal sources located around the world to provide continuous network access and data center services.
2) 4 data centers would operate on 6-hour shifts based on their local time zones during peak usage hours, while 1 data center remains always-on.
3) The network uses wavelength division multiplexing on fiber optic rings to dynamically allocate bandwidth between data centers as needed, reducing network capacity costs significantly compared to conventional network designs.
The document discusses a modular cooling solution for data centers as an alternative to traditional CRAC-based cooling. It presents the modular cooling unit design, which uses refrigerant to transfer heat directly from server racks to the building's chilled water system. A case study shows the modular units reduced server temperatures by 14-24 degrees F in a lab without using air conditioning. The modular approach improves efficiency by up to 90%, utilizes space better, and provides a payback period of 3.3 years or less compared to traditional cooling systems.
This document discusses the growing importance of measuring the energy efficiency of networking devices. As data and network traffic increases, the energy and cooling costs associated with powering network infrastructure is becoming a significant operational expense for network operators. Standards organizations have begun developing methods to measure and report the energy consumption and efficiency of networking equipment in order to drive the industry toward more eco-friendly solutions. Ixia has introduced a solution called IxGreen that allows for automated, real-world testing of networking devices' energy efficiency ratings.
The document discusses the growing issue of power management in data centers, noting that energy costs are the fastest growing expense and many data centers will soon run out of power capacity. It explains that while IT infrastructure has become more dynamic, facilities have remained static, creating a large gap between power consumption and delivery. The document argues that in order to address this challenge, CIOs must be given power budgets and power must be measured at the equipment level to incentivize changes and connect power usage to business needs.

It proposes that RSA can provide solutions for encrypting data, managing keys, controlling access to systems, collecting security information, and managing incidents to help secure the smart grid in an end-to-end manner. Finally, it suggests that EMC has capabilities across the smart grid stack from physical security to consulting that can also help utilities address security
The document discusses the views of a cynic on smart grids. It summarizes that smart grids involve completely redesigning the communications networks that control and deliver electric power to form a resilient network like the Internet. However, there are still many open issues regarding standards, integrating renewable energy, consumer costs and willingness to accept time-of-use pricing, and challenges in home energy management. Overall, while the goals of smart grids are important, the cynic believes there are still major technical, economic and regulatory hurdles to widespread implementation.
The document discusses opportunities for reducing power consumption in broadband networks. It finds that the biggest potential lies in simplifying the access layer, including the home gateway. Functions can be consolidated from the home gateway to the DSLAM or IP Edge to reduce power usage. Standardizing on open IPTV interfaces could also allow eliminating set-top boxes. Overall, rearchitecting networks with a focus on green technologies and intelligence at the Edge provides opportunities for power, capital, and operational savings.
Mobile data usage is growing exponentially as smartphones become more popular. However, most mobile data is used indoors where signal from macro cellular towers is poor. While 4G technologies can provide some improvements, the macro cellular architecture alone cannot meet long term demands. Femtocells provide a solution by creating small, low-power cellular base stations that can be installed in homes to provide dedicated indoor coverage and capacity. This improves the user experience through better signal strength and dedicated bandwidth. Femtocells also enable new applications through awareness of both mobile and home networks. However, challenges remain around interference avoidance when femtocells overlap with macro networks.
