Dell Understanding the Statement of Volatility for Servers

Dell

Appendix A. Statement of Volatility

The Dell PowerEdge R210 II 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 21 are present in the PowerEdge R210 II server.

Table 21.	Volatility Table
Server BIOS Memory		Details

Type [e.g. Flash PROM, EEPROM]:		Flash EEPROM
Can user programs or operating system write		No
data to it during normal operation?
Purpose? [e.g. boot code]		Boot Code and Configuration Information
How is data input to this memory?		Loading flash memory requires a vendor
		provided firmware file and loader
		program which is executed by booting up
		the system from a floppy or OS based
		executable containing the
