Atomdata: Xelent

Xelent was the first commercial data center in St Petersburg to hold an Uptime Institute Tier III design certification. It has 954 rack spaces. Two independent 10 kV feeders from a 110/10 kV substation supply it. Four diesel rotary UPS units in N+1 groups stand in separate buildings, so the site uses no chemical batteries. Eight free-cooling cells carry the cooling load for most of the year. More than 15 carriers serve the site over its own fiber on two independent routes, and it holds PCI DSS certification.
