Notes:
1. The system internal temperature controls the rotating speed of the fan. This value
might be exceeded if the maximum load continues under high temperature
environment or if a failure occurs in the system.
2. Sound pressure level [LA] changes from 66dB to 75dB according to the ambient
temperature, drive conguration, and operating status. The maximum value can
reach 79dB during maintenance procedure for failed ENC or power supply unit.
3. Fire-suppression systems and pneumatic sirens can generate high levels of
acoustic noise and aect system performance. It can also cause vibrations to the
hard disk drives (HDD) in the storage systems resulting in I/O errors, performance
degradation in and to some extent damage to the HDDs. The noise level tolerance
of HDDs may vary among dierent models, designs, capacities and
manufacturers. The recommended acoustic noise level for an operating
environment is 90dB or less in order to ensure reliable operations when placing a
Hitachi Vantara storage system two meters from the source of the noise.
