Networking and communication equipment are absolutely necessary in a data center to maintain a high-bandwidth network for communication with the outside world, and between the servers and other equipment within the data center. This includes components like routers, switches, the servers' network interface controllers (NICs) and potentially miles and miles of cabling. Cabling comes in various forms including twisted pair, coaxial and fibre optic. The types of cable, and their various subtypes, will affect the speed at which information flows through the data center. All that wiring also has to be organized. It's either run overhead on trays hung from the ceiling or attached to the tops of racks, or run underneath a raised floor, sometimes on under-floor trays.

Colour coding and meticulous labelling are used to identify the various wiring lines. Raised floors of data centers generally have panels or tiles that can be lifted for access to get to cabling and other equipment. Cooling units and power equipment are sometimes also housed below the floor. Other important data center equipment includes storage devices such as hard disk drives, solid state drives and robotic tape drives, uninterruptible power supplies, backup batteries, backup generators and other power related equipment. Our data center also has lots of equipment to handle temperature and air quality control, although the methods and types of equipment vary from site to site. They can include fans, air handlers, filters, sensors, computer room air conditioners, chillers, water pipes and water tanks, plastic or metal barriers or use things like chimney server cabinets to control the flow of hot and cold air to keep computing equipment from overheating.
