The data center is connected to the E.ON distribution electrical network, namely to the 110/22 kV substation of Vinohrady, with two independent HV connections via a 22 kV / 1 MW (+1 MW cold backup) HV transformer station. The substation of Vinohrady itself is powered by a primary transmission system from two substations: Čebín and Sokolnice. The power of the data center is thus backed-up to the level of the primary transmission system.
The data center is protected against a power grid failure by a pair of Volvo Penta 630 kVA (redundancy N+1) diesel generators and running time of at least 24h.
Two separate 230V/400V AC or 230V AC power supply lines, respectively two separate branches with a voltage of 48V DC, can be used to power the customer technology.
Both power supplies are available with diesel generator backup, UPS units for AC 230V and DC power units with 48V DC batteries. Everything with N+1 redundancy.
A stand-alone power cord with its own protection and measuring ability is available for each rack, and it can be extended to two or three independent supply branches if desired.
York/Carrier air conditioners (power 53 kW) with N+1 redundancy and CAREL air humidifiers are located in each hall. The controlled temperature is 22°C (+-2°C) and humidity 50% (+-10%).
The air conditioning system uses air intake into the MERO double technology floor, and the customer's technology is cooled by either air through the bottom of the rack or perforated doors. A system of hot and cold alleyways is used in the part of the hall with higher heat load.
Our data center is connected to the Czech internet center NIX in Prague with a circular topology (two independent routes) via CE Colo with a transmission capacity of 10 Gbps and TTC (also with a capacity of 10 Gbps).
Another 10 Gbps line provides connection to the Slovak peering center SIX. We take external connectivity from Hibernia Networks, Interoute, and Cogent (a backup source). It is utilized in Prague, Brno, and Bratislava with a total capacity of 5x10 Gbs, which can be increased operatively. Direct peering with peering.cz center (10 Gbps) and Google (10 Gbps) is also guaranteed.
Our data center provides customers with internet connectivity under our company's brand.
We also offer the lease of data circuits (L1, L2) up to 100 Gbps or alternatively lease of non-illuminated fibers for interconnection of technology located in the data center with another object.
In addition, a number of other telecom operators acting on the domestic market, whose services can be used, have their points of presence (PoPs) there.
All optic backbone services are available in the data center. The backbone optical routes of our company are established in this place, namely:
• two diversified routes to Prague and Ivančice
• the backup optical route to Bratislava (Slovakia) and Vienna (Austria)
• the optical route to Ostrava and Český Těšín ensuring connection to Poland
• local optical routes within Brno and South Moravia
Authorized and justified persons of the customer have 24/7/365 access through the NOC. Customers will receive a smart card for independent access to the building and the hall, and a custom key to access the rack with their equipment. The keys from the stands are kept in the electronically guarded vaults of the key economy.
All inputs to the data center building are monitored by a CCTV system with a recording device keeping the record 30 days back. The outputs of the cameras are sent to the central counter of the surveillance center.The building is secured by an electronic security system with local alarm outputs (sirens) and outputs transmitted to the central counter of the surveillance center.
The entrances to the building, individual offices or technological areas are equipped with electronic locks and sensors for verifying access privileges. All inputs are logged.
A permanent (24/7/365) surveillance center is located at the entrance to the technology halls of the data center.
The Brno data center is equipped with two independent fire detection and firefighting systems. The installed electrical fire alarm system is equipped with fire sensors. The outputs of the fire alarm system are connected to the central counter of the surveillance center.
Technological halls are fitted with semi-automatic static fire extinguishing system. The FM-200 inert gas is used as an extinguisher, which, unlike commonly used extinguishing charges (gas, aerosol, etc.), does not damage the installed technology of our customers.
The high quality of our services is provided by careful maintenance of all technological components of the data center, including the series of revisions and inspections carried out by professional staff according to valid standards.
Maintenance is carried out by our own employees in cooperation with specialized supply companies.
Load tests of diesel generators and UPS units are performed regularly, and resistance to power failure from the distribution system is tested too.
HV transformer, distribution system, fire protection system, extinguishing system, air-conditioning and humidifier units are all subject to regular inspections and checks.
