Data summary for VRTX acoustics
Acoustical data for a typical configuration
three sample blade configurations and utilizations in 23 ± 2 °C ambient (per ISO acoustical
standards) are as follows:

All M520 server nodes at idle and operating
3
— LwA-UL = 5.5 bels
4
— LpA = 37 dBA
— No prominent tones
— What this means: These levels would be masked by most open office environments, such as
air-conditioning noise and conference room conversation. For this configuration, the system
at 50% workload sounds the same as at idle.

One or more M620 server nodes with the enhanced acoustics

— What this means: These levels would be masked by most open office environments, such as
air-conditioning noise and conference room conversation. For this configuration, the system
at 50% workload is 30% louder than at idle. The enhanced acoustics option uses fewer
