Statement of Volatility – Dell PowerEdge R810

The Dell PowerEdge R810 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, remote access controllers, and

storage controllers) is available by component separately. The following NV components are present in the

PowerEdge R810 server.



Server BIOS Memory (SPI Flash, IC) Details

Size: 32 Mbit

Type [e.g. Flash PROM, EEPROM]: Flash EEPROM

Can user programs or operating system write data to it

during normal operation?

Does it retain data when powered off? Yes

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 firmware file and the

loader. System loaded with arbitrary data in firmware

memory would not operate.

How is this memory write protected? Software write protected



Server CMOS (Complementary Metal-Oxide

Semiconductor) Memory

Details

Size: 512 Bytes

Type: [e.g. Flash PROM, EEPROM]: Battery backed NVRAM

Can user programs or operating system write data to it

during normal operation?

Does it retain data when powered off? Yes

Purpose? [e.g. boot code] RTC & Configuration settings

How is data input to this memory? F2 Setup Menu during POST

How is this memory write protected? N/A

Remarks Jumper on motherboard can be used to clear to

factory default settings.

Removing CMOS battery will clear to factory defaults
