The Demand on Data Centres: Reflections on the Covid-19 Climate

In this unprecedented period of global uncertainty, ways of working, learning and living have changed with both speed and scale.

Being prepared for the unexpected is in the DNA of the data centre industry whose ‘invisible’ operations have now been classed within the definition of ‘essential services’ in most countries around the globe. Affecting organisations of all sizes, in every industry, Covid-19 has impacted business continuity across entire economies. To negate the change and challenges, optimising extant services whilst accommodating new demands has become a data centre strategic and operational imperative. 

Data is Now an Essential Utility


There are two key drivers catalysing the massive increase in demand. Firstly, is the need for computing capacity, driven by the large-scale move to remote working for many businesses and institutions. Digital infrastructure has never been so important to the world economy. The associated uptake in usage of digital applications in video conferencing, telehealth, e-commerce and e-learning, alongside those for entertainment as we all spend more time indoors, is causing a surge in need for data capacities.

New Demands are Breaking Records

The Kingston publication on data center growth highlighted our ‘insatiable’ need for data, ever more enabled by the emergence of 5G, IoT and Edge Computing. Putting this into a Covid context, data center services provider Deutsche Commercial Internet Exchange set a new world record in Frankfurt – achieving data throughput at over 9.1 Terabits per second. Vodafone reported a 50% increase in data traffic in some markets with significant usage spikes across Internet Service Providers. Indeed, BT removed home broadband data limits to support work, study and living needs.


But whilst monitoring of our ‘internet health’ does reflect an upward trend in outages this has not been to a level that corresponds with the unprecedented traffic increases experienced. And further, despite the current rise and the future projected year on year increase in data center traffic and workloads, it is important to note that global data center energy demand is forecast to decrease as monitored by the International Energy Agency - IEA. This is due to both consolidation and efficiency practices, especially cooling systems, and with some new hyperscale data centers to be run on 100% percent renewable energy.

High Performance Computing Powers Pandemic Research

The second core driver is the need for speed and computing power and this is where High Performance Computing (HPC) comes in. Vaccine and treatment research generates large data sets. Research institutions and pharmaceutical companies are utilising HPC systems at scale for the first time to undertake data simulations and calculations in areas such as epidemiology and bioinformatics. This can help dramatically reduce the development timescale for new drugs.

The Covid-19 High-Performance Computing Consortium is bringing together leaders in technology, government and academia and making available over 330 petaflops of computing speed, 775,000 central processing unit cores, and 34,000 graphics processing units. In the endeavour to better understand the virus and form treatments that can be used for potential vaccines, an incredible 330 trillion floating-point operations can now be performed per second. This is also a great example of prioritising collaboration above competition with contributors including IBM, Amazon, Dell, Microsoft, HPE and Google.


Whilst often hidden in plain sight, data centers are both the ‘power houses’ of cloud computing and the connectors of the internet, delivering on the tripartite need for more speed, more flexibility and optimal availability. Operators have worked quickly to build resilience to negate the risk of downtime and service interruption to their different user groups. With Gartner estimating the average cost of IT downtime at some $5,600 per minute, it is no wonder that this is a leading information technology concern for IT management. In the same way retail consumers have sought to hoard food and household items, as epitomised by toilet roll stockpiling observed worldwide, so data center customers have been looking to secure supplemental capacity and bandwidth to both meet the current rapidly expanding needs and as protection for business continuity too.

Managing “Virtual” Virtually

Transparency has been critical to both reassure and foster trust, with data center operators publicly sharing the criteria in place to manage, and if need be, prioritise new cloud services capacity to safeguard critical operations. An example here. There has also been significant support for existing customers, with most providers introducing short term measures such as suspension of bandwidth over usage costs. For many SME clients, where demands on network traffic and throughput have occurred that were neither expected nor planned for, the ability to increase system loads and networks beyond any extant CDR and up to the maximum throughput of their ports without penalty, can make the difference in ensuring their business viability over this tumultuous time.


But enabling business continuity for customers and partners also necessitates ensuring business continuity for the data centers themselves, especially the protection of staff, partners and suppliers. One of the key areas supporting this has been the level of knowledge sharing in the sector, especially on health, safety and wellbeing procedures, and on HR and supply chain issues. It has also involved a two-way conduit with the Government. In the UK for examplethe DCMS Data Infrastructure Resilience Team has been established to ensure data centers are factored in when key policy decisions are made.

Most significantly this has meant limiting routes for infection and dealing with the reality of site lockdowns. This has required restricted access to facilities and the introduction of split rosters whilst observing social distancing practices. It has also introduced associated availability issues primarily the reduction of personnel on site and the absence of key staff due to illness or self-isolation.

Critical facility walkthroughs are particularly important for risk reduction and so remote management capabilities are vital. The combination of sensor technology, support services for troubleshooting such as ‘Smart Hands’ and system monitoring in key performance areas notably power distribution and temperature, is enabling heightened levels of real-time remote visibility. And with this comes the capacity for advanced levels of data analysis and predictive capacity around potential incidents. Indeed, alongside satisfying the demands for computing capacity, speed, reliability and power, Covid-19 has also brought to the fore, just how much of a data center can be effectively managed remotely. But more than this, across work, study, communication and entertainment - and to better understand the virus and support interventions in treatment - the role of data centers has now moved visibly center stage.
