Client's need

For many years, Seznam is not only the most popular domestic portal and search engine. The portfolio of services it operates is growing, and today there are more than thirty of them. Most of them are managed in-house. With regard to the acceleration of development In 2013, Seznam approached us with the idea of building our own data center, which would complement the existing practice of purchasing housing services.

“The Kokura data center project is based on the idea of operational efficiency, both in terms of electricity consumption and in terms of demands on the quantity of serving personnel.”

Project specifics

On the data center construction project, we Cooperated with the investor from the very beginning. From initial study through project documentation to implementation including test operation and subsequent operational support.

The scalable data center infrastructure has been designed from in-house innovative products combined with products from renowned global manufacturers.

This project was used for the first time in the Czech Republic indirect air-free-cooling technology with adiabatic precooling developed by our company specifically for this project. By doing so, we were able to meet the investor's requirements for innovative solutions while enabling him to achieve maximum operational efficiency.

Data center capacity

1 MW IT

Power Density/Rack

5 kW

Area for IT technologies

600sqm

Availability

99.982%

Key parameters

The topology of the data center object was designed according to the technological infrastructure: optimal floor plans and layouts, optimal communication and logistics routes, separated corridors with high security, high utility flexibility and variability of premises

Thanks to the concept of unique cooling and optimized power supply, annual energy costs have decreased by an average of 40% compared to similar data centers in the Czech Republic.

The target value of PUE (energy efficiency) is on average 1.2.

The solution made it possible to omit the double floors and the associated complex distribution of cold in the halls.

Refrigeration

We have developed a special indirect air-free-cooling system with adiabatic precooling. Unique cooling with the help of outdoor air, thanks to which 95% of the time the standard compressor system is shut down. The latter is an integral part and supports 100% of the data center performance capacity.

Advantages of Mobile DC

The Modular Multifeet Architecture system uses Transformers with low loss. In combination with the cooling system, the resulting parameter of the total annual PUE (Power Usage Effectivity) reaches an operating value of less than 1.2.

Monitoring

AIMON monitoring system that enables redundant remote monitoring from our surveillance center at the same time as the customer's supervision service.

Solutions for the future

The addition of housing services from commercial providers with its own data center has provided the investor with essential competitive advantage in terms of sufficient capacity for the reliable functioning of existing services and offered scope for the development of the company and its services in the future. At the same time, we managed to secure Optimal availability of applications while at the same time achieving a cost-optimal solution to the total capacity of the data center.
