Statement of Volatility – Dell EMC PowerEdge R740 and R740XD 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.
