Statement of Volatility – Dell EMC PowerEdge – C6520

Dell EMC PowerEdge C6520 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 C6520 server.
