Acoustic requirements
The acoustic emission specifications for the XP24000/XP20000 disks array are:
•
8.27 Bels (A) sound power
•
65 dB (A) sound pressure, operator position (1 meter from the floor and surface of the rack)
You can reduce the ambient noise level caused by equipment and air conditioning blowers in your
computer room by:
•
Installing a dropped ceiling covered in commercial-grade, fire-resistant, acoustic-rated, fiberglass
ceiling tile
•
Covering the walls in sound-deadening material
•
Installing foam rubber removable partitions
