Operational Sustainability
DataLine machine rooms and engineering rooms are located in hermetic zones ("house in house"), which protect the equipment from leaks and dust. The walls of the hermetic zones contain the spread of the fire for 45 minutes.
Two independent inputs from the city power grid come to the substation and are distributed between 4 power centers. DGS are reserved according to the N+1 scheme. The DGU engine is kept warm, so that the DGU goes into operation and synchronizes in 30 seconds.
Cooling of the rooms is arranged according to the principle of "cold" and "hot" aisles. DataLine uses a chiller circuit based on ethylene glycol and water. Chillers work on the roof. In the cold season, the glycol is cooled using outdoor air (free cooling mode).
The DataLine data center is equipped with a Vesda early fire detection system and an automatic gas fire extinguishing system. Novec 1230 is used for extinguishing. Fire extinguishing system redundancy scheme 2N.
The DataLine network is distributed across two sites-OST and NORD / 4. It has points of presence on MMTS-9, MMTS-10 and is connected to traffic exchange points MSK-IX, DATA-IX. All nodes are connected to each other by their own redundant fiber-optic communication lines (FOCL). 2N network infrastructure redundancy scheme.
All parameters of DataLine engineering systems are monitored around the clock in the monitoring center. Twice a day, the engineers on duty go around the data centers and check the status of IT and engineering equipment.
