Failback
Restoring a failed system component’s share of a load to a replacement
component.
Failover
A mode of operation for failure tolerant systems in which a component has
failed and a redundant component has assumed its functions.
Failover Port
A fibre channel port capable of assuming I/O requests for another, failed port
on the loop. During normal operation, a failover port may be active or
inactive. Failover ports assume the same loop ID and, optionally, the same
node from the failed port.
Failure
A detectable physical change in hardware, requiring replacement of the
component.
Fast SCSI
Devices that increases the speed at which data is transferred as opposed to
the volume of data. These devices use data rates up to 10 MHz.
Fast/Wide SCSI
SCSI devices using data rates up to 20 MHz.
Flash ROM
Memory on an adapter containing software that can be reprogrammed
without removing it from the board.
Format
A pre-established layout for data. Programs accept data as input in a certain
format, process it, and provide it as output in the same or another format. All
data is stored in some format with the expectation that it will be processed by
a program that knows how to handle that format.
