You will often hear the words "data center" and "server room", and you all know that a server room is a room dedicated to computing equipment. Facilities such as offices, schools, and factories usually have server rooms, which are similar to a small data center that ranges in size from a closet to the entire floor of a building.

However, there are not many people who really understand the computer room. What does it look like?

Recently, the editor has taken a trip to the computer room of home science and technology. Let's share with you what common elements there are in the computer room.

Hardware equipment

At this time, the core hardware of the computer room, such as servers and data storage devices.

Cabinet

The cabinet is the unified management mode adopted by the computer room, which is used to stack the hardware system in order to use the space effectively. Network equipment, servers, distribution frames and other equipment will be installed in the cabinet.

Wiring system

A system and a set of wiring kits that manage the complexity of the cable. Ideally, this includes an overhead floor or ceiling shelf that keeps the cables out.

Power supply system

The server room usually consumes a lot of power, and the power supply and distribution system is the focus of the whole project. The computer room adopts independent access to three-phase five-wire system or single-phase three-wire power supply.

UPS configuration

Uninterruptible power supply devices are used to protect equipment from unstable power supplies, such as power surges. They are also chosen to provide enough secondary power to withstand a temporary power outage or have time to switch power.

infrastructure

Basic services, such as network equipment. The server room can be designed, and there is no single point of failure for critical infrastructure. For example, multiple Internet connections from different telecommunications companies.

Physical security

Protect the assets in the server room through internal controls such as access control, monitoring, emergency response, training, etc.

Fire fighting equipment

Fire fighting equipment, procedures, structures and other channels for employees to escape in the server room, equipped with emergency lighting equipment, maintenance tools and gas fire extinguishers.

Environment control

Control humidity and air temperature. The hot and cold operation of computing equipment is an important consideration in the design of server room. For example, cold air can be directed from the floor to the shelf and hot air can be collected from the ceiling.

Operation

Support the processes and resources of the server room, including physical tasks such as switching equipment.

Firewalls

The central computer room can use a hardware or software firewall, and the principle of configuring the firewall is to select the type of equipment according to the network size, actual concurrent connections and traffic.

Reserve

Back up data in different physical locations and hot or cold sites for disaster recovery, but preferably in another city or region.
