Dell Appendix A. Statement of Volatility The Dell™ PowerEdge™ M915 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. The NV components detailed in Table 16 are present in the PowerEdge M915 server. Table 16.

Appendix A.
Statement of Volatility
The
Dell
™
PowerEdge
™
M915 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. The NV components detailed in Table 16
are present in the PowerEdge M915 server.
