Sound
Sound Power, idling:
–
- 6.2 bel for open bay system (no hard drives installed)
–
- 6.3 bel for typical system configuration (1 bay filled with
hard drives)
Sound Power, operating:
–
- 6.2 bel for open bay system (no hard drives installed)
–
- 6.4 bel for typical system configuration (1 bay filled with
hard drives)
Sound Pressure, idling:
–
- 46 dBA for open bay system (no hard drives installed)
–
- 46 dBA for typical system configuration (1 bay filled with
hard drives)
Sound Pressure, operating:
–
- 46 dBA for open bay system (no hard drives installed)
–
- 47 dBA for typical system configuration (1 bay filled with
hard drives)
These levels are measured in controlled acoustical environments
according to ISO 7779 and are reported in accordance with ISO
9296.
The declared sound power levels indicate an upper limit,
below which a large portion of machines operate.
Sound pressure
levels in your location might exceed the average 1-meter values
stated because of room reflections and other nearby noise.
