Sakura Internet constructed a largescale data center in the suburbs of Ishikari City, Hokkaido, Japan, in November 2011.
It is assumed that the cost of this Ishikari model will be below half of that of a standard data center built in the center of Tokyo. Compared with a Tokyo-type data center, its power consumption will be reduced by a remarkable 60%. Even when using the general air conditioning electricity supply, the structure of the building has been designed to utilize the cold outdoor aircooling of the district in which it was built. In addition to that, by adopting a high-voltage direct-current (HVDC) electric supply system a further 10% power savings will be achieved, which will reduce total power consumption to around 50% of that of previous urban data center types. By lowering the Japanese IT infrastructure costs immediately in relation to global standards they aim to establish pre-eminence amongst the international competition in the cloud infrastructure.
