PowerEdge R715 Technical Guide 59
Appendix C. Statement of Volatility
The Dell PowerEdge R715 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.
Table 24 shows which NV components are present in the PowerEdge R715 server.

Server BIOS Memory (SPI Flash, IC)
Details
Size:
4 MB
Type: [e.g., Flash PROM, EEPROM]:
Flash EEPROM (Serial Peripheral Interface)
Can user programs or operating system write
data to it during normal operation?
No
Does it retain data when powered off?
Yes
Purpose? [e.g., boot code]
Boot Code, Configuration Information, EUFI
environment
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
Remarks
This flash resides on I/O board
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?
No
Does it retain data when powered off?
Yes
Purpose? [e.g., boot code]
RTC & storing system 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 settings
as well. This NVRAM resides on I/O board.
