Statement of Volatility – Dell PowerEdge R810
The Dell Power E dge R810 contains bo t h v o lat il e an d n on - 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 op t i ons (t h o s e no t so l de re d to t he m o t h er b o ar d) ar e n ot incl u d ed in t he St atement of Volatility.
Configuration option information (pertinent to options such as microprocessors, remote access controllers, and
storage contro llers) is available by component s eparately. The following NV components are present in the
PowerEdge R810 server.
