The group estimates that up to $9 million of electricity costs could be saved annually if the centre were to run 30,000 server cores.The project should be operational in April 2010 and will cost $405 million.
Sun is working with eleven other companies, including Internet Initiative Japan - an ISP, BearingPoint, Itochu Techno-Solutions and NS Solutions. They will form a joint venture with Sun. NTT Communications and Chuo University are also involved.
The disused coal mine is located in the Chubu region on Japan's Honshu island. Sun will build 30 Blackbox self-contained datacentres containing a total of 10,000 servers (cores). This can be increased to 30,000 cores if there is the demand for it.
The containers will be lowered 100m into the mine and linked to power, water cooling and network lines via external connectors.
Sun has been developing its Blackbox concept for three years and a typical one has 250 servers mounted in seven racks inside a standard 20-foot shipping container. Sun says that With T-series processors, a single Blackbox can hold up to 2,000 cores, providing 8,000 simultaneous processing threads.
Such a subterranean datacentre will be easier to secure against unauthorised entry and terrorist attacks. The Blackbox containers are robust enough to withstand earthquakes, being capable of withstanding a quake of magnitude 6.7 on the Richter scale.
