Monitoring power and performance is key to network energy efficiency - CSCI

CSCI The Climate Savers Computing Initiative (CSCI) has published a white paper on network power management. Called Power Management for Networking Devices, the paper is the second of three produced to help organisations design, specify and manage networks that are optimised for energy efficiency.

This paper addresses device power management and control and describes the importance of monitoring the power and performance characteristics of networking devices and communicating the information to network management systems. It also looks at opportunities to better design systems and devices for improved power savings and considers how application behaviour and resource use interact with energy use in networking devices.

One of the conclusions is that the design of energy efficient systems is a collective responsibility of system designers, developers, network infrastructure managers and anyone else involved in the design and operation of network systems and that power management and control is a key element. Only through understanding the power consumption of the network can you optimise its performance and make real savings in cost and meet green IT objectives without compromising network performance.

CSCI is a global consortium dedicated to reducing the energy consumption of end-to-end computing. The organisation was set up in 2007 and is led by Cisco, CSC, Dell, Emerson Network Power, Google Inc., HP, Intel, Juniper Networks, Microsoft, and the World Wildlife Fund, but now has nearly 700 members.

The three white papers in the series are:

  1. Considerations for Selecting Power Supplies for Networking Equipment and Evaluating Power Conversion Efficiency

  2. Power Management for Networking Devices

  3. Energy Efficiency Guide for Networking Devices

The idea is that together the papers will direct system designers, IT managers, and IT procurement professionals to design, purchase, install, and manage energy efficient networks.

 

Well there’s nothing new in the headline conclusion – what you can’t measure you can’t manage, but the CSCI goes into more detail in this 18-page white paper. It does also make the point that to create a really energy efficient network (something often overlooked in green IT discussions) needs the buy in of everyone involved.

A useful resource – the white papers, or at least the ones published so far, are available from the CSCI.
