Dell PowerEdge R810 User Manual
Statement of Volatility – Dell PowerEdge R810
The Dell Power E dge R810 contains bo t h v o lat il e an d n on - 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 op t i ons (t h o s e no t so l de re d to t he m o t h er b o ar d) ar e n ot incl u d ed in t he St atement of Volatility.
Configuration option information (pertinent to options such as microprocessors, remote access controllers, and
storage contro llers) is available by component s eparately. The following NV components are present in the
PowerEdge R810 server.

How is this memory write protected? Software write protected
No
firmware file and loader program which is executed
by booting up the system from a floppy or OS based
executable containing the firmware file and the
loader. System loaded with arbitrary data in firmware
memory would not operate.

are changed.
Server BMC (Baseboard Management Controller) also
known as “iDRAC Express” Internal Flash
Size: 1 GB
Type: [e.g. Flash PROM, EEPROM]: NAND Flash
