1. Save Money with Power Management Monitoring

Is your college or department under pressure to save money? Do you want to play your part in reducing greenhouse gas emissions?

If left switched on, a desktop computer and monitor will annually consume 920 kWh or around £110. If powered down after work, i.e. switched off over night, on weekends and during holidays the power and costs are reduced to only 198 kWh, around £24. To find out how OUCS and other groups have improved power management on their office computers and to get help in implementing your own green desktop computing initiatives please send an email to greenit@ oucs.ox.ac.uk or visit www.oucs.ox.ac.uk/greenit/desktop.xml

OUCS have implemented the University Power Management Monitoring and Wake- on-LAN facilities. Read on to find out more.

1.1. What is the Power Management Monitoring Facility?

The Power Management Monitoring (PMM) facility provides a graph of the total number of active nodes on a network. It thus gives a good measure of how many desktop computers are switched on throughout the day and night. The service does not record any personal data so doesn’t identify whose computer is on. The PMM was designed to visualize savings and to encourage individuals to power down their computer by letting them to see others are doing the same.

1.2. What is the Wake-on-LAN Facility?

WOL is an Ethernet standard that allows a computer to be turned on by receiving a network message (a.k.a. magic packet). We have integrated WOL with the OUCS Registration Service and HFS, allowing end users to remotely wake-up computers should they wish to connect to them. HFS can be configured to wake-up workstations shortly before the backup schedule and to turn them off post-backup.

Moreover, the OUCS Self-Registration home page (https://register.it.ox.ac.uk/self/index/) has a section, where users can set up a scheduled wake-up in the morning, so the computer is already on when they reach it.

1.3. How does a Unit Use PMM and WOL?

To use the University PMM and WOL facilities you need to install FiDo software on your network. The software is available free of charge and we provide documentation and limited email support during setup. You can use any Linux or Windows based computer to run the software, and if you host a VM environment we can provide a VM image.

Setting up Fido software can take between a few hours and a few days of work to complete, and requires experience in cetrificates, Java and networking.

We have found that many units do not have the resources to run yet another service so OUCS has decided to go a step further and offers The Fido - a ready-to-go, pre-set up device about the size of a small alarm clock which can be placed anywhere in your building where there are a spare power and ethernet socket. The FiDo hardware costs £100 and comes with a one year limited warranty. NSMS manages the FiDo for an annual fee of £400. This service includes initial device configuration, ongoing management and software patching. To discuss which option is best for you, please email greenit@oucs.ox.ac.uk.

1.4. Sign Up Now!

Over the last 12 months OUCS has worked with over 11 early adopter units to install, test and enhance the FiDo software so we can be confident of how it works in different environments. The managed FiDo service went into production at the beginning of April 2010. Remember, the sooner you get started on your green desktop computing initiative, the more money and greenhouse gas emissions you save!
