Stack Data Network (SDN)

Stack Data Network (SDN) is the first Russian network of fault-tolerant data centers. The best international practices and many years` experience of DC-outsourcing in Russia were implemented in the design and development of SDN. According to “Modern Telecommunications”, J'son & Partners Consulting and a number of independent auditing firms, SDN market share amounts to 15-20% of total outsourcing data center services market in Russia

Fault-tolerance of SDN is provided by geographical distribution of its data centers and high level of redundancy of SDN basic engineering systems (N+1)

Today SDN includes:

• two data centers in Moscow (M1 and HTH) + redundant facility (P1) 100 km away from Moscow Ring Highway (MKAD),
•  more than 5000 sq m of total square,
• 1575 sq m of server premises,
• 742 designed racks, 
• fault-tolerant backbone network of redundant communications links,
• 3-layer protection of information resources, high-level of physical security,
• continuous power supply of equipment and workplaces, 
• well-functioning air-conditioning of server rooms and workplaces, 
• work offices (the main and backup ones) whose engineering systems conform to fault-tolerance level generally accepted in SDN,
• unparalleled in quality and range package of services,
• round-the-clock presence at the site of on-duty operators in charge of proper performance of numerous engineering systems who also control operational parameters of customers` equipment (upon request) 

as well as

• unique “Stack.CUBE” technology for modular data centers of new generation 

One of key SDN advantages is the fact that design, construction and development of SDN technological sites is based on TIER III recommendations of TIA942 standard (ANSI TIA/EIA-942 – «Telecommunications Infrastructure Standard for Data Center») which has been industry standard not only for the USA but – de facto – Russia and the other CIS countries since 2005 

Prior to the official launch of SDN – two technological sites, unprecedented by Russian standards, one located at Bolshaya Akademicheskaya street (in a specially built HiTech House business-center) and the other – in the building of the largest R&D Establishment at Varshavskoye avenue were put into operation. These two facilities – Stack.HTH and Stack.M1 – became the first Moscow components of Stack Data Network and brought in a new data center era in Russia

Remote operations and maintenance of IT-systems, as well as control over their performance quality is available in all SDN data centers
