JCA: dynamic data centre engineering
JCA offers trusted world class engineering services to the data centre sector. Working across the design, construction, operation and maintenance of mission critical facilities for 17 years, JCA takes a holistic view with a pragmatic approach to the benefits and pitfalls of resilient engineering strategies.
“When working with clients like Ark, we appreciate what drives their business and understand their key business goals,” confirms JCA’s Managing Director Tom Absalom. “Engineering expertise we hold can be applied to support our partners’ business plans and market offering. In recent years, we've made great strides in terms of reduced CapEx and OpEx, albeit with increased availability and enhanced environmental credentials.”
Keeping pace with the evolutionary cycle of incremental gains, JCA ensures the products it develops and deploys are enhanced over those that have gone before. “That can only happen when you work with organisations with shared goals and strategies for the entire supply chain,” says Absalom. “We make sure everyone is aligned towards a single aim. During our time working with Ark we’ve progressed through some revolutionary concept designs which have trickled down into the world-class products you see them operating today.”
“Ark’s commitment to sustainability creates an aspiration for JCA to deliver,” maintains the company’s Chairman and Founder Ian Jackson. “It’s the perfect partnership for us to showcase our desire and commitment to invest in the lifecycle of a building asset through the implementation of new digital building technologies. Equally, we’re investigating and testing new disruptive technologies like Artificial Intelligence to improve waste management controls and also provide the strategic direction to leverage real-time information from other construction sites throughout the country.
“We’re fortunate to have customers that share our values and appreciate the advantage collaborative partnerships can bring on a long-term basis. At JCA continuous improvement is key as we strive to enhance our consistency and processes.”
Looking to the future
“We’ve been fortunate to navigate the uncertainties of the pandemic and remain able to focus on our core business objectives,” says Jackson. “Our objectives for 2021 and beyond are simple and smart. We’re well positioned to meet our goals. We’ll focus on four key areas: our people, our financial position, our customers, and our processes and controls. With over 80% of our targeted work budgeted and secured already for this year, we’re able to ensure the safety and prosperity of our staff while pushing ahead to deliver for our customers.”
“JCA, along with Gratte Brothers, are our preferred mechanical and electrical engineering partners helping us develop improved energy centre solutions. We were also keen to modularise this process so our partners came up with a unique solution which not only utilises the data center cooling to cool the energy center, but also allows Ark to build the energy center off site - improving health and safety while reducing material waste and cost. Though competitors in the market, JCA and Gratte Brothers are both owner-managed businesses that integrate well with Ark. They’re really adaptable and always looking to innovate. When we need to ensure speed to market, and in times of crisis like we’ve experienced during the pandemic, we rely on these partnerships to deliver safely to our customers.”

3 ways crypto mining is impacting the data centre industry
Around the world - particularly in Russia, Eastern Europe and China - the global rise of crypto currency values has been driving an en masse industrialisation of the mining process. The trend has been bubbling away for several years, as the home mining rig has largely found itself edged out by hyperscale server farms comprising some of the largest data centres anywhere in the industry - all designed to mine crypto.
The demands placed on a facility built and run as a mining operation are somewhat different to those placed on a hyperscale cloud facility or enterprise data centre. Reliability isn’t so much of an issue; if a mine goes down for a few hours, money is lost, but your data centre won’t take half the websites in Western Europe down along with it.
On the flipside, density and cooling are much, much more important. To make a crypto mining operation profitable, you need to be harvesting more crypto currency (be it Ethereum, Dogecoin, or the perennial Bitcoin) than you’re paying for electricity by a significant margin. As a result, some of the most efficient cooling and hyper-dense rack architecture from the past few years - like two-stage liquid cooling - has originated as a crypto mining solution. Now, hyperscale cloud operators in particular are recognising the benefits of these innovations and applying them to other aspects of the data centre industry.
1. Liquid Cooling
Crypto data centres have always been as dense as possible, with their racks running at maximum capacity all day, all year round. By contrast, the average enterprise or cloud data centre isn’t necessarily running at peak capacity 24/7; workloads fluctuate with demand. However, as that demand has skyrocketed over the past year in particular, cloud and enterprise operators have looked to crypto’s preference for liquid cooling as a way to run data centres closer to the ragged edge of performance than ever before.
One example of this is LiquidStack. The Hong Kong startup makes a revolutionary two-phase liquid cooling solution for data centres, which was developed over a number of years inside Bitfury, one of the world’s leading crypto miners. “Bitfury is sharing our knowledge with the global data center community and we are excited that Microsoft and other internet giants can benefit from our years of experience and investment to best practice liquid cooling,” said Joe Capes, CEO of LiquidStack in an interview with Data Centre Magazine.
Now, LiquidStack is going mainstream, with substantiated rumours that Microsoft is looking to adopt their DataTank solutions across its ever-expanding portfolio of hyperscale cloud regions.
2. Denser HPC
One of the issues that liquid cooling solves is how to create ultra-dense server racks that can function at high temperatures. Crypto miners have been grappling with this problem for about a decade now, and the lessons they’ve learned are being happily adopted by the burgeoning data centre HPC market - which is swelling in response to greater AI adoption and increasingly-sizable data sets.
With the density that mining rigs can achieve, server architects are cramming hundreds of kilowatts into individual racks - although it should be noted that this is still relatively rare. A 2020 survey from the Uptime Institute still found that the average density of data centre racks was growing rapidly, however.
“We expect density to keep rising. Our research shows that the use of virtualization and software containers pushes IT utilization up, in turn requiring more power and cooling. With Moore’s law slowing down, improvements in IT can require more multi-core processors and, consequently, more power consumption per operation, especially if utilization is low. Even setting aside new workloads, increases in density can be regarded a long-term trend,” said the report.
In 2020, average rack densities of 20kW and higher became a reality for many data centre operator.
3. Sustainability Concerns
Now for the more worrying news. The industrial scale and massive power consumption inherent to the crypto mining business - and the negative attention that miners are now starting to receive from government - could point towards a concerning future for data centre operators in the wider industry.
Last week, the Chinese government announced that it would open an inquiry into the participation of Beijing’s largest data centre operators - which include the country’s three largest telecom firms - in crypto mining. At a time when the PRC government is attempting a significant reversal of its approach towards sustainability, the significant power draw of crypto mining activities may be one more hurdle than China cares to deal with.
The Indian government is mulling a blanket criminalisation of all crypto mining in the country and, in the US, the State of New York is also looking into tightening regulatory restrictions on the industry.
While crypto mining data centres are not the same as cloud or enterprise facilities, operators should be careful lest the ire of lawmakers be the latest trend to make its way from the crypto sector into the mainstream.
