Japan Data Center Council’s Facilities Standard (required)

As reported in the previous blog, Japan Data Center Council (JDCC) developed a comprehensive set of items for evaluating a data center. They took all the necessary international and Japan domestic standards, integrated them, and gave them a Japanese massage”? The standards they considered were Uptime Tier, TIA-942, ASHRAE, IEEE, JEITA (Japan Electronics and Information Technology Industries Association), and FISC (The Center for Financial Industry Information Systems)

The specific factors considered for Japan were as follows:

1. Reliability of power grid—Yearly power loss in Japan is several minutes; in the U.S., 86 minutes; and in the U.K., 68 minutes. Japanese data centers can rely on the commercial grid more, and facilities do not need the elaborate power-failure schemes necessary in the U.S. and the U.K.

2. Earthquake risks—Both Japan and California have the same level of earthquake risk, but Japan’s construction law is much more stringent. If the two areas are compared using PML (Probable Maximum Loss), Japan has less risk of earthquakes.

3. Reliable equipment—Japanese equipment, such as UPS, in general is more reliable and may not require the same level of redundancy as U.S. and U.K. equipment.

On the basis of these factors, JDCC developed required and optional sets of evaluation items. The table below summarizes the required items. Note that the building law and the unit to measure the severity of earthquakes are specific to Japan.
