Statement of Volatility – Dell EMC PowerEdge MX750c
The Statement of Volatility provides you the information related to volatile and non-volatile components of different configurations of Dell EMC PowerEdge servers.
Volatile components lose their data when power cord is removed from the system, whereas, non -volatile components continue to retain their data when the power has
been removed from the component.
The following table provides information of different configurations of the PowerEdge MX750c.
