The plan layout of the server room is based on the type of server room, the task, the size of the business, the number of computer equipment, computer systems, process flow, management system and other factors to be considered, the type of server room is different, the function of the room is also slightly different.
(a) Layout design
The layout of the computer room is based on the type of room, task, business size, the number of computer equipment, computer systems, process flow, management system and other factors to consider, the type of room is different, the function of the room is also slightly different. For example: data center, the main function of the room generally has a host room, server room, storage room, tape library, network room, communications room, (total) central control room, spare parts library, etc.; ticket center generally consists of a host room, clearing machine room, printer room, receiving tickets, refused to tickets and other functional rooms; IDC machine room generally consists of a server room, testing machine room, network management center and other functional rooms; CA machine room generally have Equipment room, authentication center, key management room, data room and other rooms. However, regardless of the type of machine room, there should generally be a UPS power supply room, battery room, air conditioning room, cylinder room, changing shoes and other functional rooms or functional areas. In addition, more rain in the southern region, generally should be considered in the appropriate place to place rain shoes, umbrellas, lockers or buffer room, and to prevent cross-flow of people to and from. Layout design should pay attention to the following points:
(1) the north wall is generally no sunlight and the temperature is more constant throughout the day, so the heat generation, the temperature difference between the equipment required for the higher, it is appropriate to rely on the north side of the room layout.
(2) the same environmental requirements of the functional rooms as much as possible to centralize the arrangement, so that the functional zoning is clear, in order to use different types of air-conditioning systems to save energy.
(3) Important equipment or important functional rooms should be placed in the front of the air-conditioning system, the end of the flow of people.
(4) according to the computer system process flow arrangement of equipment or functional rooms, the correct organization of the information flow of a reasonable process, should make the circulation route and personnel walking on foot as short as possible, and the personnel should be a one-way flow to avoid back and forth cross.
(5) machine room area of the security exit should not be less than two, and should be set up at both ends of the machine room area, the opening direction should be in line with the design requirements of the fire code, the size of the door should be convenient for the entry and exit of the equipment.
(6) There should be no steps within 1.4m inside or outside the door of the evacuation exit.
(7) The deformation joints and expansion joints should not pass through the host room.
(8)Indoor and outdoor steps in the machine room area should not be less than 0.3m in width, height should not be greater than 0.15m and should not be less than 0.lm, the steps should be non-slip, the number of steps should not be less than 2, when the height difference is less than 2, should be set up according to the ramp.
(9) indoor ramp should not be greater than 1 : 8, equipment access ramp is difficult, its ramp should not be greater than 1 : 5.
(10) the location of the gas cylinder room should be close to the protection zone, the door of the gas cylinder room should not be in the protection zone.
(11) Strong power wells and weak power wells should be set up separately, and fresh air and fire exhaust channels should be set up separately and independently.
(2) If the old building is converted into a machine room, it should not open doors, windows, holes, or place projections affecting evacuation in the interior walls of the stairwells and front rooms of the original building.
(3) The fire control room should be set up to the outdoor safety exit.
(4) People-oriented, to create a separate environment for people and machines in order to facilitate the physical and mental health of staff.
In short, the 'plane layout design of the machine room should give full consideration to the reasonable planning of the flow of people - logistics - information flow, to achieve high efficiency, reasonable flow, the establishment of a good, comfortable working environment for the personnel.
(II) subsystem equipment and piping layout design
The computer room functional room brings together a large number of air-conditioning systems, electrical systems and weak power systems equipment and piping, such as ceiling panels on the lighting and emergency lighting fixtures, video surveillance cameras, anti-theft double monitoring detectors, fire alarm probes, gas extinguishing sprinklers, temperature and humidity sensors and other electromechanical end-of-arms equipment, ceiling Inside the ceiling, there are pipelines of electromechanical terminal equipment, and under the floor, there are a large number of strong power supply, computer system and weak power system cables and metal trunking, fire alarm probes, gas extinguishing nozzles, refrigerant pipes of air conditioning system, humidifying water pipes and so on. If there is no unified plan coordination design, it may cause the sub-system equipment and piping wrong, touch, leakage and other phenomena. Coordination of equipment and piping should follow the following principles:
(1) the coordination of mechanical and electrical end equipment on the top plate should be based on the decorative design effect, without violating the relevant subsystems design and construction specifications under the premise of the subsystems electromechanical end position can be moved slightly.
(2)Strong and weak electric system metal wire trough should be set up separately, and its spacing should not be less than 200mm.When strong and weak electric wire trough cross, the strong electric wire trough should be placed on the top in the ceiling, and the weak electric wire trough should be placed on the top under the floor.
(3) air-conditioning water pipe should be placed under the wire groove.
(4) The gas main and ventilation pipe should be placed close to the bottom of the beam, and when there is a contradiction between the two, the air duct should be placed above.
(5) all kinds of metal wire trough, subsystem piping placement shall not affect the air conditioning machine airflow transmission, minimize the resistance of airflow.
