The Hemel Hempstead 4 Data Centre is currently under construction, with plans to open at the end of 2021. The new data centre will become part of the London 1 facility which is due to open in the autumn of this year, 2020. It will offer clients a flexible and scalable environment with different options including high power density. 

The Hemel Hempstead 4 Data Centre will be directly interconnected with other NTT data centres located in Slough, East London and Dagenham. All of these sites are therefore connected to the company’s multi service platform which will provide the facilities with access to major cloud providers and various carriers. This allows NTT to run dual site operations and mirror the systems used at both sites. 

NTT Ltd has invested around £500 million on these latest projects with the aim to expand their footprint within the United Kingdom. Their Global Data Centre division currently operates the third largest global data centre platform, and the new London expansion is part of the company’s ongoing growth. They own and operate more than 160 data centres in more than 20 countries and regions worldwide. 

Their aim alongside expanding their global footprint is to design and operate data centres with the lowest environmental impact as humanly possible, allowing them to provide clients with state of the art modern cooling systems and energy efficient infrastructure. 

Florian Winkler, CEO EMEA of the Global Data Centers division stated that “We continue to expand to meet the demand from our clients for high quality data center space, and to protect the growing volume of their sensitive data. The UK is one of our fastest growing markets and we are pleased that the expansion in Hemel Hempstead will offer our clients additional space to support their digital business.”

NUS and NTU launch cooling project for tropical data centres

A project by The Nanyang Technological University and the National University of Singapore aims to find cooling solutions for tropical data centres

The National University of Singapore (NUS) and the Nanyang Technological University (NTU), have announced a project in an attempt to source and develop new cooling solutions for data centres located in tropical areas. According to the companies, the programme costs S$23mn (US$17.1mn) and plans to research, build and test innovative and sustainable cooling solutions. 

The Sustainable Tropical Data Centre Testbed (STDCT)

The NUS and NTU say that the Sustainable Tropical Data Centre Testbed (STDCT) will act as a research point and innovation hub for the project. Facebook, along with the National Research Foundation Singapore (NRF), is also involved, providing funding for the programme. Further support from other partners includes the Infocomm Media Development Authority, Ascenix, CoolestDC Keppel Data Centres, Red Dot Analytics, and New Media Express. 

Commenting on working with the companies, Facebook Vice President of Infrastructure, Alex Johnson, said: “We are excited about the opportunity to partner NUS, NTU, Keppel Data Centres and the CoolestSG community to develop innovative solutions that reduce the carbon footprint and energy consumption of the average data centre, particularly those located in tropical areas like Singapore”. 

The NTU and NUS highlight that Singapore houses 60% of Southeast Asia’s total data centre market, and aims to supply 12% of the country’s total energy needs by 2030. This results in the need to reduce the carbon footprints and power consumption of data centres, meaning more innovative cooling solutions are required, the NTU and NUS said. 

Professor Chen Thuan, Deputy President of Research & Technology at the NUS, said: “Data centres are a critical enabler of the digital economy, but the average data centre can exert a significant environmental burden. Aligned with RIE 2025, sustainability is a key research focus of NUS, and our researchers have deep expertise in developing integrated solutions for tropical, urban and Asian settings”.

How will the Sustainable Tropical Data Centre Testbed (STDCT) help to provide cooling solutions?

According to the NUS and NTU, the STDCT will be built using equipment such as a novel desiccant-coated heat exchanger and a StatePoint Liquid Cooling System (SPLC) designed by both Nortek Air Solutions and Facebook. The institutions also say they will adopt chip-level hybrid cooling to ensure servers remain cool. 

Furthermore, the use of artificial intelligence (AI) will aim to manage the “smart operations” of the technologies so that the data centres are water and power efficient, as well as able to preserve equipment and servers. 

The NTU and NSU said in a joint statement the combination of the cooling technologies could reduce energy consumption “significantly” and greenhouse gas emissions by up to 25%, compared to traditional air-cooled data centres. If adopted industry-wide across the entire tropical region, the energy usage of the data centre industry could potentially be lowered by at least 40%”, the companies said. 

The STDCT is expected to be operational by 1 October 2021.
