State
Hitachi does not test storage systems and data drives (includes HDDs, SSDs, and FMDs)
for compatibility with fire suppression systems and pneumatic sirens. Hitachi also does
not provide recommendations or claim compatibility with any fire suppression systems
and pneumatic sirens. The customer is responsible to follow their local or national
regulations.
To prevent unnecessary I/O error or damages to the hard disk drives in the storage
systems, Hitachi recommends the following options:
1. Install noise-reducing baffles to mitigate the noise to the hard disk drives in the
storage systems.
2. Consult the fire suppression system manufacturers on noise reduction nozzles to
reduce the acoustic noise to protect the hard disk drives in the storage systems.
3. Locate the storage system as far as possible from noise sources such as
emergency sirens.
4. If it can be safely done without risk of personal injury, shut down the storage
systems to avoid data loss and damages to the hard disk drives in the storage
systems.
Damage to the hard disk drives from fire suppression systems or pneumatic sirens will
void the hard disk drive warranty.
