< HOME Advances in data centers in line with smaller and denser servers Servers and storage devices are rapidly becoming smaller and denser, and each equipment rack in a data center is becoming heavier, consuming more power, and generating more heat. As a result, data centers must be able to meet more advanced specifications and fulfill more sophisticated needs. In addition, security requirements are becoming more stringent. Data centers must meet stricter zoning and access control requirements as well as provide detailed analysis and response to risks ranging from natural disasters to human threats. Our considerable experience in the design and construction of advanced data centers allows us to meet the stringent requirements of future data centers. Effects on data centers of smaller and denser IT devices Rapidly changing specifications for data centers Data centers constructed in 2000 can no longer meet current requirements. Data centers constructed in 2000 Next-generation data centers constructed after 2008 Target IT devices Servers Blade servers Antiearthquake measures Seismically isolated floors and racks Seismically isolated buildings Floor height 4,000 - 4,200 mm 4,400 - 6,000 mm Floor load 300 - 500 kg/m2 1,000 - 1,500 kg/m2 Raised floor height 300 - 500 mm 500 - 1,000 mm Electrical power capacity 1.5 - 2.5 kVA/rack 4.0 - 8.0 kVA/rack Access control Noncontact IC card Biometrics as well as measures to prevent unauthorized access by two or more persons at a time.
