Keep data center clean by monitoring and controlling gaseous contamination.
Non-operating
Table. Noise level (recommended)
State Specification
Operating 90 dB or lower*
Non-operating 90 dB or lower*
* Fire suppression systems and acoustic noise: When activated, some inert-gas fire-suppression systems release pressurized gas at high velocity through multiple nozzles in the data center, generating high levels of acoustic noise. Pneumatic sirens can also generate high levels of acoustic noise. High levels of acoustic noise can cause vibrations to the media in the storage system, resulting in I/O errors, performance degradation in the media, and to some extent damage to the drives. Media noise-level tolerance varies among different models, designs, capacities, and manufacturers.
The recommended acoustic noise level of 90 dB or less represents the current operating environment guidelines for which the storage systems are designed and manufactured for reliable operation when placed 2 meters or more from the source of the noise.
Note: The storage systems and media are not tested for compatibility with fire-suppression systems or pneumatic sirens. In addition, Hitachi does not recommend or claim compatibility with any fire-suppression systems or pneumatic sirens. The customer is responsible for following applicable regulations.
To prevent I/O errors and damage to the storage system due to high levels of acoustic noise:
  • Install noise-reducing baffles to mitigate the noise to the media in the storage system.
  • Consult the fire-suppression-system manufacturer about noise-reduction nozzles to protect the media in the storage system.
  • Locate the storage system as far away as possible from noise sources.
  • If it can be done safely and without risk of personal injury, shut down the storage system before the noise occurs to prevent data loss due to damage to the media in the storage system.

DAMAGE TO MEDIA FROM FIRE-SUPPRESSION SYSTEMS OR PNEUMATIC SIRENS VOIDS THE MEDIA WARRANTY.
