Statement of Volatility – Dell DSS 1500 Dell DSS 1500 contain 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. R6Configuration option information (pertinent to options such as microprocessors, remote access controllers, and storage controllers) is available by component separately.
