Statement of Volatility – Dell PowerEdge R420

Dell PowerEdge R420 contains 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 R420 server.
