fabric-loop port
(FL_Port)
An F_Port can support an attached arbitrated loop. An FL_Port on a
loop has the AL_PA hex'00', giving the fabric highest priority access to
the loop. An FL_Port is the gateway to the fabric for NL_Ports on a
loop.
failback
See
failover
In an active-active configuration, failover is the act of temporarily
transferring ownership of controller resources from a failed controller
to a surviving controller. The resources include virtual disks, cache
data, host ID information, and LUNs and WWNs. See also
fault tolerance
The capacity to cope with internal hardware problems without
interrupting the system’s data availability, often by using backup
systems brought online when a failure is detected. Many systems
provide fault tolerance by using RAID architecture to give protection
against loss of data when a single disk drive fails. Using RAID 1, 3, 5,
10, or 50 techniques, the RAID controller can reconstruct data from a
failed disk drive and write it to a spare or replacement disk drive.
fault-tolerant virtual
disk
A virtual disk that provides protection of data in the event of a single
disk drive failure by employing RAID 1, 10, 3, 5, or 50.

Fibre Channel-Arbitrated Loop (FC-AL)
.
Fibre Channel (FC)
A set of standards for a serial I/O bus capable of transferring data
between two ports at up to 100 Mbyte/sec, with standards proposals to
go to higher speeds. Fibre Channel supports point-to-point, arbitrated
loop, and switched topologies. Fibre Channel was completely
developed through industry cooperation, unlike SCSI, which was
developed by a vendor and submitted for standardization after the fact.
