What environmental controls are important for a data center?

Data center environmental controls include temperature management maintaining 64 to 81 degrees Fahrenheit with hot and cold aisle containment, humidity control between 40 and 60 percent relative humidity to prevent static discharge and condensation, uninterruptible power supply systems providing battery backup during short outages, generators for extended power failures, power conditioning to protect against surges and sags, water detection sensors under raised floors and near cooling systems, and positive air pressure to prevent contaminants from entering.
