Rack-mountable server

As servers are often noisy and they need a stable power supply, good Internet access, and increased security, it is usual to store them in dedicated server centers. This requires reducing the power consumption, as the extra energy used generates more heat thus causing the temperature in the room to exceed acceptable limits; hence normally, server rooms are equipped with air conditioning devices. Server casings are usually flat and wide (typically measured in "rack units"), adapted to store many devices next to each other in a server rack. Unlike ordinary computers, servers usually can be configured, powered up and down or rebooted remotely, using out-of-band management, typically based on IPMI. [Server (computing). Wikipedia]
