Facilities that provide uncompromised attention to mission-critical operations

Facility systems with seismically-isolated structures that are safe and secure

AT TOKYO's data centers ensure highly-dependable power supply with multiplexed power supply systems and reliable redundant facilities. They are fully prepared for the effects of a wide range of environmental disasters with incoming power that uses underground cables, and power sources with UPS (uninterruptible power supplies). For worst-case scenarios, they are equipped with high-speed recovery systems that are resistant to vibration, using EG's (emergency generators) which are required as a pre-requisite for data center selection by many customers. With the combination of strong, solid site selection with seismically-isolated structures achieving the highest safety rank after undergoing earthquake risk analysis by a world-class risk management company, we have achieved the creation of data centers that are highly resistant to any operational shutdown.

Key Points
