Controller 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 (DUPs, Unified Server Configurator) containing the firmware
file and the loader. Storage adapters loaded with bad firmware will not provide storage controller behavior.
FRU
Factory only. Not customer updatable.
Integrated Mirroring
NVSRAM
Embedded storage firmware controls this data
iDRAC6 Enterprise
VFlash
Preloaded media before installation, or remote out-of-band upload of user data (i.e., ISO images, files) or local
server read/write capability to use like a hard disk
