Reasons why server racks may experience additional noise
Note that it is not only active devices that generate noise. Let's analyze the common causes of noise:
cooling system. Each cabinet is equipped with a ventilation system to cool the operating equipment. Install fans to force air to circulate through the unit and exchange heat. If fans are outdated, contaminated with dust, or spin too fast, they can be the cause of noisy system operation.
thin wall. Most models of server furniture are made of durable metal. However, it is thin and does not absorb noise. To make it more soundproof, an additional layer of soundproofing material is required.
Depending on the source of the noise, the handling will vary. Therefore, it is necessary to determine what exactly is working too noisy.
Possible Noise Reduction Solutions
When system administrators deal with large data centers with dozens of server racks spread out, the noise can penetrate even the walls of the house. In this case, soundproofing the server room makes sense. Hire a construction team to improve the walls, doors, and ceilings of the chosen site. Wall and ceiling soundproofing will be the best solution for larger systems.
However, you can act more locally by soundproofing server racks or specific equipment. If the problem is related to a noisy cooling system, do the following:
Check the fan and remove dust and other debris. If the fan is working too loudly, it is most likely contaminated. Dust deposits on the blades and causes a running noise. Disassemble the ventilation system, turn off the fan, and clean it. Using a vacuum cleaner is an effective way to remove dust from blades.
If the fan is spinning too fast, reduce the fan speed. However, make sure that this solution does not affect the cooling strategy and cause the system to overheat.
Upgrade the ventilation system. If your fans are too bad, replace them with modern models. Improved fan models work quieter, consume less energy, and provide greater efficiency.
If the cabinet is too thin, the solution is as follows:
If the cause of the loud noise is from servers or other active equipment, you can reduce the noise level emitted by adding additional soundproofing material to the cabinet walls and doors.
