Statement of Volatility – Dell EMC PowerEdge FC640 and M640

The Dell EMC PowerEdge FC640 and M640 contain both volatile and non-volatile (NV) components. Volatile components lose their data after removal of power from the

component. Non-volatile components continue to retain their data even after the power has been removed from the component. Configuration option information

(pertinent to options such as microprocessors, remote access controllers, and storage controllers) is available by component separately. The following components are

present in the PowerEdge R640 servers.
