Intel® RAID Software User Guide 336
F
Fast initialization A mode of initialization that quickly writes zeroes to the first and last
sectors of the virtual drive. This allows you to immediately start
writing data to the virtual drive while the initialization is running in the
background.
Fault tolerance The capability of the drive subsystem to undergo a single drive
failure per drive group without compromising data integrity and
processing capability. The Intel
®
RAID Controllers provide fault
tolerance through redundant drive groups in RAID levels 1, 5, 6, 10,
50, and 60. They also support hot spare drives and the auto-rebuild
feature.
Firmware Software stored in read-only memory (ROM) or programmable ROM
(PROM). Firmware is often responsible for the behavior of a system
when it is first turned on. A typical example is a monitor program in a
system that loads the full operating system from a drive or from a
network and then passes control to the operating system.
Foreign configuration A RAID configuration that already exists on a replacement set of
drives that you install in a computer system. The GUI management
utility software allows you to import the existing configuration to the
RAID controller, or you can clear the configuration so you can
create a new one.
Formatting The process of writing a specific value to all data fields on a drive, to
map out unreadable or bad sectors. Because most drives are
formatted when manufactured, formatting is usually done only if a
drive generates many media errors.
Full charge capacity Amount of charge that can be placed in the battery. This value
represents the last measured full discharge of the battery. This
value is updated on each learn cycle when the battery undergoes a
qualified discharge from nearly full to a low battery level.
G
Gas gauge status Hexadecimal value that represents the status flag bits in the gas
gauge status register.
H
Hole In the GUI management utility, a hole is a block of empty space in a
drive group that can be used to define a virtual drive.
Host interface A controller property indicating the type of interface used by the
computer host system; for example, PCIX.
Host port count A controller property indicating the number of host data ports
currently in use.
Host system Any computer system on which the controller is installed.
Mainframes, workstations, and standalone desktop systems can all
be considered host systems.
