Acoustics

Dell EMC PowerEdge MX7000 acoustical design is guided by the following principles:
• Deliver sound levels that are appropriate for end users' deployments
• Deliver sound quality (e.g. tones, hums) that does not distract those working in proximity to the product
• Tune fan control to quickly attain and maintain target fan speeds while minimizing oscillation
• Deliver efficient thermal design that meets reliability and performance requirements at the lowest fan speeds
• Minimize vibration for sound quality (e.g. no rattles) and reduce disturbances to rotational hard drive media

Deployment Environment

MX7000 infrastructure is designed for use in unattended data center environments; its acoustical output will be too loud for office
areas in all configurations. Dell EMC provides options for the customer to reduce or limit acoustical output for attended data center
applications, including: configuration restrictions, sound cap profile (iDRAC), and a hardware acoustical baffle.
