University of Nottingham WakeMyPC goes live
University saving £325 every day with PowerMAN and WakeMyPC
"PowerMAN/WakeMyPC is an entirely new software based solution that offers a cost-effective way of working with the existing estate of IT equipment and doesn’t require the end user to have any additional knowledge to be more environmentally friendly."
"The network at the University of Nottingham is fairly typical of most organisations in the sector, in terms of the equipment used and the multi-site nature of the campus environment. Our developing and testing the solution within this environment reassures other prospective customers that the product will work for them."
The University of Nottingham (UoN) is a world-class university ranked in the UK top 10,
the European top 30 and in the top 1 per cent of all universities worldwide. A member of
the Russell group, the university was named Times Higher Education "University of the Year"
in 2006, Times Higher Education "Entrepreneurial University of the Year" in 2008,
and runner up in the 2010 Sunday Times "University of the Year". With an annual
budget in excess of £500m, the university has over 30,000 UK-based students together
with further campuses in Malaysia and China.
The Information Services (IS) department manage over 10,000 UK-based desktop computers for
both staff and student users. Services range from email and internet access in student
study bedrooms, to state-of-the-art learning and studying facilities, software and high performance
computing in Schools and Institutes.
Like many progressive organisations, UoN was very aware of the pressures to reduce PC running
costs (rising energy prices, new legislation with financial penalties for non-compliance and
a social responsibility to protect the environment) as part of its wider Carbon Reduction strategy.
The University purchased Data Synergy’s PowerMAN power management software in 2009. Initially
implemented in student facilities the software achieved immediate gains. The metrics that
PowerMAN provides identify the worst offending groups of PC’s and measure the savings that are
Maximising coverage of staff workstations
"PowerMAN monitors a total of 15,382 staff and student computers of which 10,521 are
staff computers. Of the total staff computers 94% are being managed with only 6% opting out"
The second phase of the power management project was to introduce energy saving to staff
workstations. The university team quickly identified that many users required remote desktop
access and this would limit the effectiveness of the power management strategy.
"We needed an effective solution to ensure that our PC power management strategy
would get the highest take-up from staff users. We realised that one of the biggest barriers
to entry for staff is the need for remote PC access. This highlighted a requirement for a
simple and secure way to wake PCs on demand to work alongside our power management solution."
The university worked with Data Synergy to introduce and trial the WakeMyPC software. This
allows users to wake their own PCs using a friendly web-interface. This software based solution
was a pragmatic approach that allowed users to use their existing desktops avoided expensive
replacement of existing hardware. The solution delivers a comprehensive quick win and significantly
enhances an energy saving initiative.
"As there is significant financial pressure on the sector at this time, solutions
that build upon existing infrastructure do offer genuine cost effectiveness."
The WakeMyPC software required quickly implemented and very minor changes to the university’s
network configuration. WakeMyPC integrated with the university’s existing security authentication
system and ensured a secure way to implement Wake-On-LAN. After initial testing the IS team
rapidly enabled WakeMyPC across the entire estate.
The project was publicised through the university intranet and went live in March 2011.
"Our main aim was to maximise the number of PCs under active power management and
effect organisation-wide change, without impacting on anyone’s productivity or ability to
do their work when desired. We wanted to achieve the largest possible financial savings
and reductions in associated CO2 emissions, without compromising academic and administrative output."
Following the successful deployment of WakeMyPC the university has 96% take-up of power management
on staff PCs with only essential experimental equipment and core administrative systems being
opted out. The resultant implementation has achieved an estimated reduction of 600 tonnes
per year of CO2 providing a useful contribution of over 4% of the University’s targeted annual
saving for 2015. The financial saving is also significant. The project required minimal staff
time and network changes.
"Studying the figures for one week before and one week after activation, the savings are equivalent to 1.96 tonnes of CO2 or £325 every day"
By using PowerMAN in tandem with WakeMyPC the project’s main aims have been achieved:
"In large organisations with devolved management structures it is often difficult to effect wholesale behavioural change. Solutions such as WakeMyPC allow the central organisation to deliver change without necessarily having to enforce a change in individual’s behaviour."
"The University of Nottingham is happy to act as a reference site for this solution and share the benefit of our experience in achieving such a successful outcome with the rest of the sector"
- To maximise the number of PC’s under active power management
- To implement organisation-wide change without impacting on productivity or the ability of end-users to do their work when desired
