Data center

The data center is a specially secured server room (a Lampertz modular cell) whose structure and supporting systems provide a very high level of protection against fire, earthquakes, electromagnetic interference, gases, liquids, dust, burglary and other environmental influences.

It is also equipped with supporting infrastructure that ensures a high level of security, including fire suppression, uninterruptible power, temperature control and restricted access.

• Entrance doors provide fire resistance, burglary protection and sound insulation in accordance with the relevant standards.
• Access control is further restricted by magnetically locked doors and an identification system.
• Every permanent administrator must identify themselves with a magnetic card and code on each entry, and all entries are recorded at the control center. Access for operational personnel becomes more restricted at higher security levels. At the highest security level, entry to the secure server room is controlled by a single-person access chamber, admitting only properly identified individuals.
• Each server cabinet is opened using a combination lock.
• Redundant video surveillance system.
• Physical security is provided by a specialized local armed security service, which monitors all security zones through the control center and conducts regular security patrols.
• Power cabling for the secure server room's uninterruptible power supply uses two physically separate power feeds.
• Uninterruptible power supply system (2 static UPS units rated at 2 × 625 kVA and 2 active STS switching matrices rated at 2 × 1000 A).
• The uninterruptible power supply systems are installed in two separate rooms, each with its own air conditioning, access control and alarm system. Each room contains one pair consisting of a UPS and an STS.
• Three days of autonomous operation are provided by a 1.2 MVA generator system, connected to the utility supply through a 2 MVA transformer station (2 × 1 MVA).
• Electrical connections are protected against direct physical access intended to damage them.
• Each server cabinet is powered by at least two physically separate circuits connected to the uninterruptible power supply system.
• Antistatic raised floor with ventilation panels.
• Separate floor cable trays for all power and communications wiring.
• Redundant technical cooling units (2+1), LIEBERT Hiross Himod 46 UF, using a cold-zone system.
• Fire detection system (aspirating and conventional).
• Fixed fire suppression system using FM 200 gas.
• Connection to the central ventilation system with appropriate fire dampers.
