Inzai 2 – Moving Closer to Completion

Ian Dixon, VP Operations Colt DCS

Building a data centre is a unique construction project. It differs considerably from building an office, a residential complex or a sports facility. Not only in how the floor space is used, but in the power, cooling, security and other aspects that are needed to ensure reliable, defendable and consistent operation of all the vital computer and networking equipment stored within it.

We’ve been working on the construction of Inzai 2, our second data centre on the ‘Inzai campus’ and our fourth in Japan, for almost a year. Based across six floors, the facility will provide ten 5,000m2 of floor space for tenants, with a floor dedicated to storage, electrical and HVAC resources, and a mezzanine floor for offices and workspaces.

We are now entering the final stages of completion of the site, a project that took a major step forward recently when Inzai 2 moved from external generator power to running off mains electricity, the event was marked by a traditional Shinto ceremony on site. This shift to internalised power infrastructure is a major milestone in the final preparations before the first tenants arrive on site later this year.

It’s an important step in the final fit-out and ‘debugging’ of the site. It allows our engineers to test the power infrastructure of the site under a variety of different load scenarios, as well as to test that the local grid can indeed supply the power the data centre will need. If transformer upgrades and other expansion work are needed further along the public power distribution network, now is the time to identify this, rather than when Inzai 2 enters full operation.

In our experience of the market, the Asia Pacific region is experiencing a significant uptake in demand for cloud services, creating growth in the market for additional data centre facilities to deliver cloud services to local markets. Gartner has forecast the public cloud services market in region will grow from $10 billion today, to a staggering $13.6 billion by 2019. The largest public cloud operators , known as the “big 3’ are all seeing significant growth in the Asia PAC region, further bolstering demand for in-country data centre facilities from which major services can be delivered and integrated.

The demand for managed cloud and professional services itself has especially grown in countries like Japan, which have a mature cloud landscape. This is due to a surge in big data and other complex workloads such as enterprise resource planning (ERP) being migrated away from on premise systems to cloud based solutions.

In moving these and other resources to the cloud, customers can benefit from scalable processing, storage and other IT resources. At the same time, it moves a considerable amount of IT spending away from large capital expenditure (CapEx) investments and over into more scalable operational expenditure (OpEx), that is directly linked to the size and scale of the customer’s business needs. The first phase of the data centre is due to be handed over in Q4 this year. This will see our customers fully operational and live in the data centre. A significant achievement in a twelve month period is anticipated for all the teams across Colt DCS who are involved in the project. To mark the occasion we are head down planning our grand opening event, if you’re interested in finding out more we will be covering during the event then please feel free to get in touch.



Colt Data Centre Services (DCS), the global data centre operator, has today announced the completion of a tier three data centre expansion project in Madrid.

The new fully-functional site delivers increased capacity to support customer demand in the region and is part of Colt DCS’ aggressive growth strategy for 2017.

The significant investment made to upgrade the carrier-neutral data centre will deliver improvements in reliability and an energy-efficient infrastructure. An additional 645m2 has been added to the site, including 400m2 at full fit-out and 245m2 at half fit-out ready to support 170 and 119 new racks, respectively.

The data centre’s total capacity now stands at 1,845m2 of white space for customer colocation racks with an available mains power of 1,200 watts per square metre. Colt DCS expects the expansion to create new business opportunities in target sectors including financial services, media and the public sector.

In addition to capacity upgrades, Colt DCS has taken significant steps to enhance customer service quality, reliability and the power efficiency of the site – innovations that will offer competitive advantage while awarding customers a best-in-class environment to develop their operational performance.

Key features include:

  • Ultra energy-efficient technology up to 96.8 per cent to replace old UPS units
  • New hybrid cooling towers to reduce water consumption and provide free cooling throughout the year to improve energy usage
  • New room cooling units with variable speed compressors, variable water flow and energy efficient fans
  • New humidification system including energy efficient ultrasonic technology with mineralised water
  • New pumps with enhanced control strategy for better energy usage
  • Flexible rack layout and extended maintenance space
  • Early fire detection system to improve data centre safety and reliability

“Our investment in our carrier-neutral data centre in Madrid recognises the increase in market demand for colocation services across many key verticals in Spain. We want to provide our customers with the latest innovations in data centre technology. This is in addition to providing an environment where they can run their businesses reliably, efficiently and cost effectively. The expansion showcases Colt DCS’ commitment to the region and to customers with operations in Spain. It is also an example of our aggressive growth strategy for this year and beyond.”
