5Keeping the Space Cool and Green
The raised-floor venting system shoots cooled air back up into circulation. Hot air from hundreds of servers and storage arrays rises to the ceiling and is channeled outside to the always-on cooling system. Newer, cooler-running processors in data center equipment require keeping the data center temperature at a moderate 72 degrees—instead of 65 to 68 degrees required for many older data centers. Power and cooling savings over time are substantial, and carbon emissions have been reduced by about 21 percent over earlier-generation equipment.
All the power supplies are located above the racks for easy access, maintenance and repair. Sky vents suck hot air out of the room. All the power conduits and networking are in the ceiling. Typically, in a raised-floor scenario, the cabling is channeled through the space between the building floor and the server racks. That model generates a lot of additional heat, which rises up to the servers that are already overheated.

9Hands-On Hydrogen Fuel Cell
Fujitsu is the first company in Silicon Valley to install a hydrogen power fuel cell for a data center. This will generate about half of the power needed to cool the servers in the data centers and computer labs at the Sunnyvale campus. The company estimates that it will pay for itself in 3.5 years. It meets the most stringent air emissions standards set by the California Air Resources Board and produces 35 percent less CO2 per megawatt-hour than an average fossil fuel-based power plant.
11Major-League Cooling Apparatus
Fujitsu spared no expense in upgrading its cooling system. There also is an air-side economizer on the roof. Whenever the outside temperature falls below a certain level, the equipment enables purified intake of cool air and the escape of heated air, which further reduces the cost of keeping the data center cool.
