Appendix A. Statement Of Volatility; Statement Of Volatility - Dell PowerEdge R815 Technical Manual

Dell
Appendix A.
The Dell™ PowerEdge™ R815 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, system memory, remote access controllers, and
storage controllers) is available by component separately.
Table 19 details the NV components present in the PowerEdge R815 server.
