SAS 6/iR Integrated

Controller
Configuration
Data

Loading flash memory requires a vendor-provided firmware file and loader program which is
executed by booting 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.
