Statement of Volatility – Dell PowerEdge T620

Dell PowerEdge T 620 contains both vol a til e an d non-volatile (NV) components. Volatile components lose their
data immediat ely up on r em o v al of p ow e r from t he 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 controllers) is available by component separately. The following NV components are present in the
PowerEdge T620 server.
