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
Heat dissipation, power consumption, and air flow specifications
Heat and power specifications differ between the XP24000 and XP20000 disk arrays. See the
following tables for information on your specific disk array.
