Heat Dissipation and Noise

Heat Dissipation and Noise

Heat Dissipation and Noise (Applicable to 5000 and 6000 Series)

A storage system can run steadily using the heat dissipation system carried in its own fan modules. An external device is necessary to remove the hot air discharged from a storage system from the equipment room to ensure proper air circulation.

Heat Dissipation

Traditional heat dissipation modes are as follows:

  • Controller enclosure

    Cooling air enters from the front end through small holes on the interface modules. After dissipating the heat of interface modules, controllers, and power modules, the air is discharged out of its back end by fans. The controller enclosure dynamically adjusts rotational speed of the fans based on the operational temperature of the storage system.

  • Disk enclosure

    Cooling air enters from the front end through the space between disks, passing the midplane, into the power modules and expansion modules. After dissipating the heat, the air is discharged out of its back end by fans. The disk enclosure dynamically adjusts rotational speed of the fans based on the operational temperature of the storage system.

For better maintenance, ventilation, and heat dissipation, pay attention to the following when installing the storage system in the cabinet:

  • To ensure smooth ventilation, the cabinet should be at least 100 cm (39.4 inches) away from the equipment room walls and at least 120 cm (47.24 inches) away from other cabinets (in front or behind).
  • To keep air convection between the cabinet and the equipment room, no enclosed space is allowed in the cabinet. 1 U (44.45 mm or 1.75 inches) space should be left above and below each device.

The airflow parameters of the storage system are shown in Table 4-13.

Noise

The disks and fans make noise when in operation, with fans being the major noise source. The intensity of fan rotation is associated with the temperature. A higher temperature leads to greater rotational speed by the fans, which in return creates greater noise. Therefore, there is a direct correlation between the noise made by a storage system and the ambient temperature in the equipment room.

When the temperature is 25°C, the parameters of the noise generated by the storage system are shown in Table 4-15.
