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 Ethernet
A local area network (LAN) transmission standard that provides a data rate of
100 megabits per second (referred to as 100BASE-T). See also Ethernet.
100Base T: In 100 Mbps (megabits per second) Ethernet (known as Fast
Ethernet), three types of physical wiring can carry signals:
• 100BASE-T4 (four pairs of telephone twisted pair wire)
• 100BASE-TX (two pairs of data grade twisted-pair wire)
• 100BASE-FX (a two-strand fiber optic cable)
This designation is an IEEE shorthand identifier. The “100” in the media
type designation refers to the transmission speed of 100 Mbps. The “BASE”
refers to baseband signaling, which means that only Ethernet signals are
carried on the medium. The “T4,” “TX,” and “FX” refer to the physical
medium that carries the signal. (Through repeaters, media segments of
different physical types can be used in the same system.)
Fast SCSI
Devices that increases the speed at which data is transferred as opposed to
the volume of data. These devices using data rates up to 10 MHz. Compare
with Fast/Wide SCSI, Ultra SCSI (Fast 20 SCSI), Ultra2 SCSI (Fast 40
SCSI), Ultra160 SCSI (Ultra3 SCSI), and Wide SCSI.
