Equipment noise
The acoustic emission values [loudness in dB (A)] for the VSP storage
system storage system are:
• Front/rear = 65 dB (A)
• Both sides = 65 dB (A)
Heat output and air flow
The following table lists the heat output and air flow requirements for the
VSP storage system components.
Both the control chassis and the disk chassis contain front and rear fans to
circulate air through the chassis from front to back. Air flows in through the
front bezel to the rear of the component and exits through the perforations
in the rear door. Either the front fans or the rear fans can cool the chassis
by themselves. The racks do not contain fans. Airflow is from front to back.
