Data center

Design of engineering systems in data-processing and data-storage centers (COD, Data center).

ЦОД_Здание.jpg

This project was completed in 2010. Our company didn’t design and build all of the engineering systems in the data center, but definitely did a large chunk of them. Our company designed and built cold-supply, air-conditioning, vapor-softening, condensate drainage and smoke removal systems.

Overall information:

OST data-center belongs to the “Dataline” company (some pictures presented on this page were taken from the company’s website www.dtln.ru) and is located in a separate building at Moscow, Borovaya st., 7, b.10.

According to the rating made by “Modern Communications” company in October of 2010, “DataLine” took 4th place in the total amount of building spaces given to technological facilities.

Today the data-center has six machinery rooms that contain 583 rack spaces. The total area of the center is 2723 square meters and has a set total power of 5000kW. The building partly consists of cleanrooms that allow protection of telecommunication equipment from dust, corrosive chemical admixtures and other pollutants in Moscow’s air.

Power supply:

The power supply of the data-center is constructed according to the 2N plan: power supply from the city (“Mosenergo”, 7th district) comes in 2 lines to 2 step-down transformers.

If the main power supply breaks down, the data-center switches to three diesel generators (model: SDMO T1900). Oil and antifreeze always stay warmed up, which allows the generators to start up within 60 seconds. The generators are reserved according to N+1 plan.

While generators are starting up the data-center gets power from Uninterruptible Power Supply system. The capacity of the batteries in the system can supply the building for 10 minutes.

The capacity of the fuel tanks allows 6 hours of work and active contracts with fuel-delivery companies allows the data-center to operate on its own resources forever.

Cooling and air-conditioning systems:

Halls are cooled down by “cold” and “hot” corridors. Cool air comes from the internal blocks of the air-conditioning systems then goes through the grids on the floor and then goes into the hall between the front walls of the racks.

Data-center OST is equipped with precision air-conditioners with ethylene-glycol thermofors produced by Emicon and Freon conditioners produced by Uniflair. There are also four cooling machines (chillers) set outside of the building that maintain the temperature of the building in the range of +6°C to +12°C.

Air-conditioning system is reserved by N+1 plan.

Besides the temperature, humidity of the air is also controlled inside of the machinery rooms.

During winter time, heat coming out of the machinery is mostly distributed into heating of the office and technical rooms of the building. The amounts of heat are so large that they almost allow the building to heat up itself without any additional heat coming from the city’s heat-supply lines.

Fire-fighting system:

Data-center OST is equipped with an automated system that fights fire with gas. It immediately locates the fire, alarms people and automatically stops the fire.

The fire-fighting substance is Freon 125. It is delivered to the rooms through ducts in case of fire.

Fire-fighting system is reserved by the 2N plan.
