Kao Records claims to possess built the UK’s first wholesale colocation facility to rely upon 100% free-air cooling, as segment of a push to develop its purchasers with access to excessive-efficiency computing (HPC) environments that assemble no longer rely upon mechanical refrigeration tactics to sustain them frigid.

The Harlow-essentially based operator specialises in providing colocation capability to hyperscale companies and existence sciences-connected organisations and is within the course of a multi-year buildout of its datacentre campus.

This involves the creation of its KDL1 datacentre, where it has opted to deploy a free-air, indirect evaporative cooling (IEC) machine – reportedly the principle time such abilities has been dwelling dwell in a UK wholesale colocation facility.

The machine capacity that the sizzling air generated by the power’s servers is released into the ambiance, as an change of outside air being pumped in to sustain the equipment frigid.

“The datacentre industry has generally stood by tried-and-examined systems of using specific applied sciences,” Kao Records chief working officer Paul Finch advised Computer Weekly. “Kao Records became designed to self-discipline and lead the market, accommodating the needs for future-proofing and better computational efficiency in parallel with demands for sustainability.”

Since Kao Records’s inception in 2014, the company has made a concerted effort to differentiate its datacentre setups from these supplied by the wider UK colocation community by championing the positioning fabricate guidelines that are on the general favoured by the hyperscale cloud and web giants when building their very dangle facilities.

To this cease, its datacentre campus – understood to be one of many UK’s easiest – became the principle within the country to be licensed as OCP-Ready. This suggests it has been designed to the factors dwelling out by the Fb-backed Birth Compute Mission, which can possess an interest by encouraging operators to contain open source hardware to toughen the effectivity and scalability of their datacentres.

The company moreover confirmed on 25 Might perhaps perhaps 2021 that its datacentres had got certification from Nvidia that states it has functionality to toughen and host workloads that rely upon the chipmaker’s most up-to-date graphics processing unit (GPU) applied sciences, along side artificial intelligence and excessive-efficiency computing workloads.

Being ready to accommodate such workloads is one other the explanation why Kao is favouring a free-cooling intention inner its datacentres, on legend of mechanical cooling systems would retract in space that shall be put to higher utilize for its purchasers’ compute necessities, acknowledged Finch.

“The advantages of this trend are many and began accurate thru the attain share, with a long way better space utilisation and a long way fewer mechanical systems required,” he acknowledged. “This supplied lowered complexity and allowed us to provision for GPU-intensive systems alongside outmoded colocation.”

Additionally, mechanical cooling processes are inclined to be more energy-intensive, so there are some sustainability and payment advantages that Kao Records will reap thru this project, too.

“The free-cooling topology moreover offers a chain of sustainability advantages to customers, lowering each and each carbon dioxide and grisly fluorinated gas emissions, while permitting us to moreover put in drive the monitoring of gaseous contaminates accurate thru the technical space,” acknowledged Finch.

“This present the peace of mind that customer server and storage warranties are never put at possibility, while guaranteeing better ranges of reliability.”

Kao Records worked with its longstanding fabricate and assemble accomplice JCA Engineering on the project, which, in flip, enlisted the aid of datacentre fabricate and simulation utility maker Future Facilities to be obvious the operator’s theoretical opinion to assemble a free-cooled facility would work in practice.

Future Facilities did this by making a digital twin of the proposed datacentre region using its utility, so that it would possibly perhaps perhaps pinpoint any capability and theoretical efficiency factors that can emerge once the IEC became deployed within the true world.

As segment of this work, Future Facilities moreover drew on the computational fluid dynamics (CFD) simulation capabilities of its 6SigmaDCX utility suite, which supplied Kao Records with insights and predictions as to how its IEC machine would procure in differing inner and exterior environmental stipulations.

“6SigmaDCX is a CFD kit which is blended with the modelling of systems fresh in datacentres and systems that work with datacentres, so we are moreover emulating control systems for cooling systems infrastructure,” acknowledged Alex Dorn, engineering supervisor at Future Facilities.

“We are along side bodily characteristics, as smartly as cooling systems and servers, and we strive and incorporate the thermal efficiency profiles of equipment [in these models], as smartly. This suggests the atmosphere is dynamic that we are simulating – so it’s no longer honest a static 3D space with airflow being simulated animated spherical.

“We’ve bought all of these assorted systems dynamically reacting to their atmosphere, and then that’s linked thru the CFD simulation.”

As regards this project, Future Facilities became before everything enlisted by JCA Engineering to assemble a fabricate prognosis of the exterior datacentre using the 6SigmaDCX kit, which Dorn admits is somewhat a “novel” activity to be asked to procure.

“Modelling accurate thru the industry on the general has an inner point of interest, so it became attention-grabbing to be asked to glimpse at the exterior fabricate of the power,” he acknowledged.

“They [JCA Engineering] came to us and acknowledged we’ve bought this fabricate, and we’d luxuriate in to be obvious it in actuality works. So we needed to clarify a shortlist of climate scenarios that we felt had been representative and moreover lined any possibility that shall be skilled, and then we created what we name a baseline.

“With out a doubt, that is the principle model of the mannequin [digital twin] where we feel that what is deliberate is lawful for goal, and also you use that as your reference point going forward.”

From here, the company’s work on the Kao Records assemble progressed so that its utility became then weak to mannequin the inner of the power, that can even be a refined activity, acknowledged Dorn.

“The utility itself is extraordinarily honest and exacting on legend of it is continuously being improved thru evaluation and trend, but the mannequin produced is dependent on the inputs and the accuracy and the appropriateness of the inputs as wel,” he acknowledged. “The predominant here is deciding on the excellent inputs, and finding the facts obligatory to train the systems fascinated by the fabricate and operation.”

On the time of the project, exterior modelling of datacentres using digital twin abilities became somewhat unprecedented, and is a functionality Future Facilities easiest began building into its utility suite in 2017.

“It’s pushing the envelope, but it became obligatory to procure this viability stamp overall [for the Kao Data build] on legend of how else are you able to be obvious your fabricate is going to work and that datacentre is going to operate OK?” acknowledged Dorn.

And while this project is a UK first, Dorn is confident that with Kao Records demonstrating the viability of free-air cooling on this country, assorted operators can also decide for a identical systems in their unusual-assemble facilities.

“It is a dauntless transfer and it makes it clear that it is achievable,” he added. “It is a extraordinarily possibility-averse industry and this reveals that there’s now the science to aid arrange novel designs and arrange the chance of novel designs and novel approaches.”
