Statement of Volatility – Dell PowerEdge R720 and
R720XD
Dell PowerEdge R720 and R720XD contain both volatile and non-volatile (NV) components. Volatile
components lose their data immediately upon removal of power from the component. Non-volatile components
continue to retain their data even after the power has been removed from the component. Components chosen
as user-definable configuration options (those not soldered to the motherboard) are not included in the Statement
of Volatility. Configuration option information (pertinent to options such as microprocessors, remote access
controllers, and storage controllers) is available by component separately. The following NV components are
present in the PowerEdge R720 and R720XD servers.
