Dell POWEREDGE R710 - Manual (Page 5)

Component
Can user programs or
operating system write data to
it during normal operation?
Purpose (e.g., boot code)
Integrated Mirroring
NVSRAM
No Stores configuration data of HDDs.
iDRAC6 Enterprise
vFlash
Yes, when enabled, installed,
and the media does not have
the write protect switch applied.
Storage of logs, user images like files,
drivers, OS's, etc.
Component How is data input to this memory?
Planar
System BIOS SPI Flash
Loading flash memory requires a vendor-provided firmware file and loader program
that 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. Future firmware releases may add support for
recovery of a bad/corrupted BIOS ROM image via the iDRAC (administrator privilege
plus specific firmware, binary, and commands).
LOM Configuration Data
Loading flash memory requires a vendor-provided firmware file and loader program
that is executed by booting up the system from a floppy or OS-based executable
containing the firmware file and the loader. LOMs loaded with arbitrary data in
firmware memory would not operate.
iDRAC6 Controller ROM N/A
iDRAC6 Controller RAM iDRAC embedded system.
System CPLD (EPROM)
Loading flash memory requires a vendor-provided firmware file and loader program
that is executed by booting up the system from a floppy or OS-based executable
(currently only DRMK utility support) containing the firmware file and the loader.
System loaded with arbitrary data in CPLD memory would not operate.
System CPLD (RAM) Not utilized
iDRAC6 Express Internal
Flash
iDRAC OS: Loading flash memory requires a vendor-provided firmware file and loader
program that is executed by booting up the system from a floppy or OS-based
executable containing the firmware file and the loader. System loaded without a good
iDRAC firmware image yields a non-functional iDRAC. Managed Services Repository:
Various partitions are loaded via vendor-provided firmware file and loader program
just like iDRAC OS.
