Page "Server (computing)" Paragraph 18

As servers need a stable power supply, good Internet access, increased security and are also noisy, it is usual to store them in dedicated server centers or special rooms.

This requires reducing the power consumption, as extra energy used generates more heat thus causing the temperature in the room to exceed the acceptable limits ; hence normally, server rooms are equipped with air conditioning devices.

Server casings are usually flat and wide, adapted to store many devices next to each other in server rack.

Unlike ordinary computers, servers usually can be configured, powered up and down or rebooted remotely, using out-of-band management.
