  • Telefonica uses much of the space in the datacenter itself, but customers ranging from petroleum companies to supermarkets are also using the center.

  • The datacenter uses free cooling to keep the rooms at the optimum temperature.

    During the winter, hot air generated by the equipment is recycled and mixed with cooler air to maintain the right temperature, while water vapour can also be mixed in with the air to reduce temperatures during the very hot summer months. Telefonica says free cooling is used for about 92 percent of the year.

  • Phase one of the Alcala datacenter was the construction of the first 25,000 square metre building, where six of the seven rooms are now operational. Eventually, Telefonica will expand the datacenter to include another four buildings, each with four rooms. The final datacenter should cover around 80,000 square metres, Telefonica says.
