Abstract

Systems and methods are disclosed that may be implemented to locally and remotely record, control, monitor and analyze sounds generated in an information handling system environment, e.g., such as in a server environment. Among other things, remote monitoring and observation of sound in a data center environment may be implemented to assist administrators with data center management and forensics analysis related to physical chassis events (e.g., such as chassis access and/or chassis intrusion), as well as providing live streaming, and local technician recorded sound bite capabilities. A sound policy may also be implemented involving server sound optimizations that works in conjunction with system thermal and power algorithms.
