Because a stable temperature is very important for the hardware in the datacenters we use N+1 down flow cooling units. Because of the raised floor in the datacenters combined with floor parts which are perforated and located in a cold-aisle setup, the cold air is blown up very precisely for the most effective cooling possible.
If there is a fault on our energy suppliers grid, we have multiple 800kVa generators at our disposal. The generators are preheated 24/7. This way the generators are able to supply the whole datacenter with power within a few seconds.
Our uninterruptible power supply units (UPS) are highly efficient. Because of the newest techniques of our vendor relation Eaton we are able to achieve over 99% efficiency. These results are achieved through advanced power core technology, and continues to uphold the load with maximum protection.
Because of our expertly designed power grid we can ensure the power feed to all servers will be uninterrupted at all times. Everything has been designed in accordance to TIER3 classifications. This means, for example, that if one device will malfunction, a second one will keep everything online.
