STACK.P1 DATA CENTER

Stack.P1 data center is the remote component of SDN (100 km away from Moscow Ring Highway (MKAD)). After significant improvements and upgrades in 2007 this data center became the redundant component of SDN and now holds a special place in the plans of further network expansion

Upgrades and improvements have allowed to put into operation a complex of engineering systems which comply with up-to-date requirements to fault-tolerant data centers 
Below are the operating parameters of this technological site:

FAULT-TOLERANT POWER SUPPLY

Uninterruptible power supply of P1 data center is provided by 3 UPS units of 60 kVA each. 2+1 (2 “necessary + 1 redundant) approach has been implemented. Emergency power supply is provided by the diesel-generator of 250 kVA. External electric power is supplied via transformer of 800 kVA. Configuration and operating parameters of P1 data center power supply system enable to maintain specified operating mode of ICT systems and engineering equipment in any situation including full transfer of the data center onto autonomous power supply

The loading capacity of racks with substandard equipment may be increased to 8 kW

FAVOURABLE CLIMATE CONDITIONS

Climate control is performed by precision air conditioning system which consists of 5 conditioners
Climate control system maintains air temperature and humidity in the data center computing premises in accordance with international standards (22 ± 5 degrees Celsius, humidity 45 ±5 %). Air-conditioners are operating on an N+2 basis: if two air-conditioners are not operating (e.g. planned preventative maintenance), favorable climate conditions in the computing premises of the data center remain the same

Due to balanced ventilation system installed in the data center, there is no dust in the server room. Pollution and, consequently, overheating of network and server equipment has been fully eliminated. Implementation of the latest technologies for separation of cold and hot air aisles allows to maintain temperature from 17 to 19 degrees Celsius from access floor to false ceiling

NETWORK RESOURCES

PSN data center is equipped with all necessary telecommunications resources to supply telecommunication links from any provider located in the two main Moscow traffic exchange points – M9, M10. Fiber-optic cables of telecom providers are available in the data center (list of telecom providers)   

COMPLEX SECURITY

All data center premises hosting customer systems are equipped with water-tight covering (false ceiling) and drain holes to prevent flooding. Floor decks are made of reinforced concrete. Loading capacity of access floor is not less than 1000 kg per square meter (2200 lbs). Higher loading capacity of up to 2000 kg per square meter (4400 lbs) is possible. There are no windows in server premises

All finishing materials are manufactured of incombustible materials

All premises and adjacent territory of the data center are guarded 24/7. Customers and personnel in server rooms and auxiliary premises (premises for on-duty operators, monitoring centers, rooms to perform works with equipment and etc) are controlled by means of dual access control system and individual access cards. Access to outside perimeter with common and auxiliary premises is possible with individual access cards

Stack.P1 CCTV system allows to track video received from entry/exit door areas, aisles, racks, adjacent territory, as well as technical premises and rooms for racks with substandard equipment  on a round-the-clock basis. Independent on-line video surveillance over customer`s equipment with video data transmission to customer`s security service is possible

Server premises of data center are equipped with automatic gaseous fire suppression system

ROUND-THE-CLOCK MONITORING

Specialists of maintenance service who do the monitoring of server and telecommunications equipment deployed in the data center, as well as telecommunications links, electrical and engineering systems are available in P1 data center

Most of Stack.M1 operating parameters is available in the other Stack Data Network data centers. SDN includes Stack.M1 and Stack.HTH in Moscow and Stack.P1 100 km away from Moscow Ring Highway (MKAD)
