How is data input to this memory?
Power Supply
PSU
Microcontroller
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 (Unified Server
Configurator) containing the firmware file and the loader. PSUs loaded with bad firmware will
not provide PSU functional behavior and result in PSU system faults.
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.
