The digital world is advancing with growing momentum which is having a massive impact on data centres and energy consumption.
Data centre managers today are facing a constant uphill battle with skyrocketing energy usage and energy costs. Strict environmental guidelines to reduce emissions and go carbon neutral by 2030 have been implemented to balance data centres’ rapidly increasing global share of energy consumption. Many now invest in next-gen DCIM to effectively manage and take control of their assets, energy efficiencies and provide power budget forecasts.
With the mounting pressure of eco deadlines to improve energy efficiencies, data centres have the perfect opportunity to really take a look at their facilities, warts and all, to see exactly where they are wasting valuable resources and where energy and money saving cuts can be made.
The first step is to get a complete overview of what is being spent and where.
A Breakdown of Energy Costs, Rack by Rack
If we’re going to get into the nitty gritty of it all, a good place to start is by looking at the cost to power one rack in a data centre. Generally speaking, the power consumption is about 7kW, depending on location and configuration. Well over half of US data centres experience power densities of around 15kW per rack during higher peak demands, and it isn’t unheard of when some data centres hit over 20kW a rack.
Converted in money terms, the cost of this amounts to anything up to $30,000 a year per rack in the US. And overall, the cost of running a data centre ranges between $10 million and $25 million a year. If energy usage can be fully optimised, rack by rack, server by server, the potential savings could be significant.
If we compare these US stats with current 2022 electricity prices in the UK of £6.77 per kW per day, we’re looking at costs of £17,000 for a 7kW rack up to £49,000 for a 20kW rack per year. And in some London colocations, the cost of a full rack at around 3.5 – 4kW can be anything up to £21,000.
Some businesses, like Thrive, are making attempts at reducing energy costs, with their colocation data centre allowing customers to use its buying power with energy suppliers to keep costs down, as well as investing in greener cooling.
Let’s take a look at how these figures could increase. Ireland, for example, is experiencing a data centre boom and their data centres are forecast to grow by 13,000 square metres a year from 2022 to 2026, with revenue expected to at least double over that four year period. While this is incredible news for business, it comes with the obvious extra energy cost implications. By 2030 Irish data centres could account for a third of Ireland’s energy use, expected to cause rolling blackouts countrywide. While most countries won’t quite match up to these figures, globally, data centres consume around 2% of electricity which is predicted to increase to as high as 8% by 2030.
Where Else is Energy Being Used in Data Centres?
Aside from the fully functioning servers, there are other main areas in which data centres spend most of their energy budgets and could be optimised to cut costs.
An essential part of data centre management is cooling. The amount of energy consumed by data centres can result in excessive heat generation which it is vital to control in order to protect systems from overheating and failing.
Earlier this year during the summer heatwaves it was all over the news when Google’s London data centre cooling systems became insufficient and servers suffered failures as a result.
Following the unexpected rises in temperature which managed to push these front-runner’s cooling systems over the edge, some data centre businesses are considering taking advantage of ‘free cooling’ to save on their cooling costs by migrating their data centres to cooler climates.
At least with an active server you are getting something for your money, but all data centres waste a vast amount of their valuable energy budget on energy squandering idle and obsolete servers. Among thousands or even hundreds of thousands of servers it’s not glaringly obvious when servers are running unused or whether energy ought to be diverted elsewhere. Without an accurate overview of all assets, it’s impossible to properly manage obsolete and outdated equipment that will be eating into energy budgets.

How Can DCIM Improve Energy Consumption and Keep Costs Down?
With such huge costs, data centre management’s primary task is to closely monitor their energy consumption and efficiency. Innovative DCIM offers immediate visibility over all assets with real-time insights into each rack and each server’s energy usage. With precise data centre monitoring, each asset can reach optimal performance and energy wastage can be reduced through the weeding out of underused and idle equipment, reducing the overall energy cost per rack.
The smartest solution for business owners to gain control over where and how their energy budget is being spent is investing in revolutionary next-gen DCIM software which provides a more accurate overview of an entire data centre space. This allows data centre managers to see exactly when servers and racks are running and when they’re actually needed, saving time, resources and money.
Combine that with a digital twin, an accurate, virtual replica of every asset and system across all data centre sites, and you have the ability to predict changes and mitigate risks before they occur, thus reducing energy wastage.
Our smart DCIM also effectively monitors data centre cooling systems to pinpoint problems and make adjustments to humidity and temperatures. Throw AI (Artificial Intelligence) and machine learning into the mix and data centre teams can monitor and predict what, where and when to cool, generating massive energy savings of up to 30%! AI can also be put to work in many other areas to cut costs, from reducing the need for human intervention in mundane tasks, so your skilled workforce can be redirected elsewhere, to identifying energy patterns and optimising efficiency.
When you have a full overview of all assets and how they’re functioning, you can make decisions on where to conserve energy. Assetspire’s 3DCIM offers full and immediate visibility over all assets and will locate in real time and rectify any idle servers for you, invaluable in the fight against energy inefficiency.
You’ve read how Assetspire’s next generation intelligent data centre management software can be the solution to a myriad of inefficiencies within data centres, now is your chance to give it a try and see how much it can save you. Quick to deploy, use on your mobile on the go, our Spire platform will address the real issues around asset management and provide smart solutions, yielding a fast return on your investment.
