The device cabinets are furnished with two Power Distribution Units (A + B). Device cabinet 52 RU has 2 x 48 sockets and device cabinet 12 RU has 2 x 13 sockets. Electricity consumption and use are measured and reported per data cabinet, and the invoicing for consumption is based on kWh. PDUs suitable for monitoring phase/socket-specific consumption can be ordered as a supplementary service.
Each device cabinet and equipment space is provided, by default, with a certain amount of power and cooling capacity, which cannot be exceeded without a separate agreement.
At the Telia Helsinki Data Center, cooling air is conveyed to data cabinets from under the installation floor. For this purpose, there is an empty room of about one metre under the floor for the cooling air. The installation floor consists of grid panels or perforated plates of 600 x 600 mm on top of a steel frame.
The power supply of the data center is implemented with two separate supplies backed up by UPS (Uninterrupted Power Supply) devices N+1 and an accumulator. N+1 means that there is enough redundancy capacity even if one device were broken. The redundancy is also based on the use of generators N+1. “UPS 10 min/GEN N+1”, for example, means that the power supply has 10 minutes of accumulator redundancy time and, in addition, diesel generators will ensure power supply in the case of power failures of over 10 minutes.
