Statement of Volatility – Dell PowerEdge R430
Dell PowerEdge R430 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 R430 server.
