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.
The cooling systems sit on the roof of the datacenter, pulling in cool air and pushing out warmer air.
The modular design and construction of the datacenter means systems controlling power and cooling are mirrored across all rooms. Telefonica says this helps with maintenance as well as construction.
