There are 14 computer rooms for 1587 racks in OST-1, OST-2, OST-3 data centers. The floor area of the data center is 6172 sq.m.
Computer rooms and engineering facilities are located in special containment ("house in the house"), which protect equipment from leaks and dust. The walls of the containment can suppress the spread of fire during 45 minutes.
Each data center has its own 24/7 security service. Entrances to the territory and premises of the data center are equipped with access control system (ACS), which protects from unauthorized access. Data centers are also equipped with alarm button for requesting emergency assistance from federal police.
All visitors of the data center must sign in and show ID
All inner and surrounding area of the data center are under full-time control of video surveillance system.
Video from the cameras is transmitted to monitors of security service and recorded. Video archive is stored for three months at least. Online broadcast from cameras placed near your equipment can be arranged to your Personal Account and DL Monitor mobile app.
24/7security and video surveillance
On request your racks can be protected by a with special fence (cage), individual security cameras and access control system.
Power supply system
The power is supplied from the city to the data center through two independent routes to step-down transformers.
2independent routes in each data center
If power from the city is lost, the data center automatically switches to power supply from diesel generators. On OST site there are 11 diesel generators: 3 SDMO T1900 and 8 FG Wilson. Diesel generators have N+1 redundancy.
The engine of each diesel generators is maintained in a warm state, so generators reach operating conditions and synchronize with each other within 30 seconds. The fuel tankage of the diesel generator is enough for 6 hours. Existing contracts for prompt delivery of diesel fuel ensure autonomous operation of the data center as long as necessary, even in case of long-term failure of the urban electrical network.
30 secondstime for diesel generators to reach operating conditions
While diesel generators are getting into the gear, OST data center is powered by uninterruptible power supplies (UPS) APC MGE Galaxy 7000 and batteries.
15 minutesthe data center will be able to work on batteries. This is more than enough for diesel generators to start and undertake power supply of the data center
Computer rooms are arranged according to ‘cold’ aisle / ’hot’ aisle layout. In ‘cold’ aisle constant microclimate is maintained.
23–27 ̊Сtemperature in ‘cold’ aisle
In OST data centers cooling circuits with various types of coolant are used : ethylene glycol and freon. Freon cooling of the system is based on precision air conditioners by Schneider Electric and external blocks, placed on the roofs of data centers.
Chiller scheme works on ethylene glycol. In computer rooms installed Emicon air conditioners, on the rooftop - chillers Stulz CyberCool 2 and Hiref. In cold weather, the glycol is cooled by outside air (free cooling mode).
N+1redundant cold supply system
Data centers are equipped with VESDA early smoke detection system and automatic gas fire suppression system.
The extinguishing agent is Freon-125.

DataLine network is distributed between two sites - OST and NORD. It has points of presence on the MMTS-9, MMTS-10 and it is connected to Internet exchange points MSK-IX. All nodes are connected to each other by DataLine’s own redundant fiber-optic communication lines (FOCL). In OST data center works Meet-Me-Room, which allows customers to connect to the network operators.
2Nredundant telecom infrastructure
All parameters of the engineering systems are monitored around the clock in the monitoring center. Twice a day on duty engineers bypass data centers, and check the status of IT and engineering equipment.

In your Personal Account and mobile application DL Monitor you can monitor the basic parameters of the data center systems and your own equipment, placed in OST data centers.
