All IT data centres should be aware of the EU’s code of conduct for data centres, which provides a framework measuring and improving your data centre’s energy efficiency. As part of the UK government’s Energy Savings Opportunity Scheme (ESOS), all data centres in the UK need to be assessed to ensure they meet the set standards.

We’ve put together this post on how to monitor and improve your data centre’s energy efficiency through real-time monitoring and by managing your data centre environment.

A truly green data centre.

How to Measure the Energy Efficiency of your Data Centre

The most effective way to measure your data centre’s energy is to implement a monitoring and reporting strategy. By installing energy monitors in your data centre, you’ll be provided with insights into variables such as the temperatures of your hot aisle and cold aisle systems, your carbon dioxide emissions and your overall energy consumption.

With energy monitors, readings can be taken manually or generated automatically, which can then be used to produce reports through energy and environmental reporting consoles. These reports can show how frequently equipment in your data centre is used, which then enables you to implement management systems to reduce your overall consumption.

How to Improve your Energy Savings

Alongside encouraging behaviour change within your organisation, the way in which your data centre is set up can have a significant impact on your energy usage.

Ideally, your data centre should be planned in such a way that your direct current is spread out across the server, so that any power spikes are distributed evenly over the whole system, reducing their overall impact. Other ways you can improve energy savings include:

  • Reusing waste heat from your data centre to provide additional heating to your office spaces
  • Choosing energy efficient equipment and distribution unites and making use of any energy saving features
  • Using more efficient IT software that doesn’t use as much energy
  • Consider what small changes can be made to reduce power usage, e.g. install energy efficient lightbulbs, heat water using urns instead of kettles etc.

In order to properly manage and improve your data centre’s power usage, you need to install smart software that can manage your whole data centre environment continuously and in real-time.

How to Demonstrate your Energy Savings

Data Centre Management systems like Sensorium can quickly identify where there’s excess energy being used and pinpoint specific areas, departments and even individual servers. Once improvements have been implemented, this holistic approach can then be used to measure the impact of improvements and provide you with real-time and historical data, which can be used as part of the ESOS assessment.

If you choose to take your energy saving efforts to the next level and gain ISO50001 Energy Management System accreditation, management systems like Sensorium will certainly come in useful. To gain accreditation, you’ll need to demonstrate how you use data to improve your energy usage, measure the results and work towards continually improving your energy management processes.

At Secure IT, with every project that we undertake, we are able to report and advise on all areas of Power Usage Effectiveness (PUE) and Data Centre Infrastructure Efficiency (DCiE). This enables our customers to keep track of their ongoing energy costs and identify ways to reduce them further.

We pride ourselves on keeping up to date with changes in industry guidance, technology and accreditations so that your data centre is as energy efficient as possible.
