Frontier IDC is a subsidiary of Yahoo Japan, operator of Yahoo data center in the country and the data centers of many customers. Mr. Yamanaka is a member of JDCC - an association of operators and suppliers. The data center has undergone three major events: self earthquake, tsunami crippled the nuclear power plants along the northeast coast, and power shortages due to the nuclear plant was paralyzed. Most of the data center in Japan will exceed the building regulations which were very close this country, so only minor damage when an earthquake occurs, he says Yamanaka. The modern data center in Japan is built on the "shock absorbers" giant - insulated panels (Isolator) is made ​​of metal and rubber to help the building "floating" on the quiet while below ground shaking from side to side.Some data centers also have isolation level floor plates (floor-level) and level rack (rack-level). Additionally, all servers are installed on the price (rack server), coolers and other equipment are secured firmly to the floor. The most effective damping at the building, Mr. Yamanaka said, and some damping at the supports did not work in the quake. However, he said, only 5 rack servers reported serious damage in all data centers in Japan. One other mitigating factor is 70% of data centers in Japan are in the Tokyo area. No data centers in the northeast, where the tsunami hit. However, the ground shook in Tokyo is also quite intense in the last 2 minutes.
