Statement of Volatility – Dell PowerEdge R450

Dell PowerEdge R450 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 R450 server.
